What can be cooked from squid: quick and tasty

Increasingly, when installing water supply or heating, both in apartment buildings and in private houses, craftsmen prefer polypropylene pipes not metal, as it was before. And this is not surprising, because such material is definitely more convenient to install. This fact allows all the work to be done even by a person without any specific knowledge or experience. At the same time, make heating in a private house from polypropylene pipes with your own hands, you can even alone, without resorting to anyone's help. Today we will consider how you can do this kind of work, how difficult it is and what is needed for this.

Polypropylene pipes - their advantages over metal

Previously, when installing heating with metal pipes, there was a problem with bends. I had to make an additional threaded connection in the form of an elbow, which is not very good. After all, the more individual parts there are, the more vulnerable the structure. Of course, it was possible to bend the pipeline at the desired angle, but without special equipment, such actions were difficult to perform. There was a risk of kinking, which entailed a loss of pressure in the system. Another problem was corrosion, which over time rendered the metal unusable.

Now, if heating from polypropylene pipes is installed, these problems are not. This material bends easily in any direction. Of course, this does not mean that you can do whatever you want with it, you need to know when to stop in everything.

With regard to fittings (connections), we can say that their quality is much higher than that of metal. With the right approach, a welded joint or elbow will last no less than a solid pipe. In other words, you shouldn't be afraid to make connections. The main thing to learn for installing heating with polypropylene is owning an iron (a device for soldering pipes and fittings). This is quite simple and will not be particularly difficult.

The advantage, which cannot be ignored, is that this material does not corrode, which significantly increases the service life. Many experts say that heating quality welded from polypropylene pipes can be called eternal.

Types and characteristics of polypropylene pipes for heating

Today, the manufacturer offers a fairly wide range of similar products. It is imperative to pay attention to this when purchasing - after all, design differences also affect the operating conditions of polypropylene pipes. Such products can be either single-layer or multi-layer. Let's start with the single-layer ones, as the simplest ones. They can be labeled:

1. PPH- this is the simplest type used for the installation of industrial pipelines, as well as cold water supply.
2. PPB- Slightly more complex type. These pipes are suitable for heating installation, which also does not exclude their use in cold water supply systems.
3. PPR- The scope of these pipes is already a little wider than that of the previous ones. It is allowed to use in systems not only cold, but also hot water supply.
4. PPs- the most difficult in composition. The admissible temperature limit is up to + 95 ° С. Such pipes can even be used in steam rooms. Of the shortcomings, a rather high cost can be noted.

Reinforced polypropylene pipes for heating are called multilayer - fiberglass or aluminum is laid between the plastic layers. Such plumbing products can already be bent, although they cook no worse than single-layer ones.

Reinforcement can be as follows:

• external - solid aluminum;
• external - perforated aluminum;
• inner - aluminum sheet;
• internal - fiberglass;
• composite materials.

In the article, we will analyze in detail the main selection criteria, what types of pipes exist, their advantages and disadvantages, how and how to insulate the heating system, advice from professionals.

It should be understood that the external reinforcement makes it quite difficult to solder the pipeline (the coating at the welding points has to be removed), which means it is better to pay attention to products with fiberglass or composites.

Which propylene pipes for heating is better, of course, it is up to everyone personally to decide, but if you pay attention to the characteristics, then the fiberglass-reinforced ones have no competitors. Indeed, in this case, the product, in principle, cannot delaminate. The reason for this is that the fiber is literally soldered into polypropylene during manufacture, and does not stick to the layers, as is the case with an aluminum interlayer.

Standard sizes and diameters of polypropylene pipes

The main thing that should be understood if it is decided to replace the heating line in the house from metal to polypropylene is the difference in external dimensions. It is the inner diameter that should coincide, while the outer one will differ. This happens due to the fact that the walls of polypropylene pipes are thicker than those of steel. When distributing heating in houses, products with a cross section of 32 to 40 mm are most often used. If it comes oh, then in this case 16 mm is enough.

“The inner diameter of polypropylene pipes for heating a private house, presented on Russian counters, is always identical to the section of old steel pipes... This is done for the convenience of replacing old communications. ”

There is one more nuance that should be considered when purchasing such material. The size of the PP pipe is usually indicated precisely by the outer diameter, which means it is very easy to make a mistake. As a result, you will either have to go back to the store and change pipes (if possible), or pay the money again and purchase what you need. To prevent this from happening, you need to do the following. Knowing the necessary inner size it is required to clarify the outer diameter of the PP pipe and subtract two wall thicknesses from it. This is how we get the data we need.

Average price of propylene pipes for heating in the Russian markets

Several major manufacturers of propylene glass-fiber-reinforced pipes for heating are presented on the shelves, the prices of which, by the way, are quite reasonable. The cost depends, like any other product, mainly on the brand. The quality of almost any of the market leaders is quite acceptable. Of course, this does not apply to polypropylene pipes, which are sold at too low a price. In general, if there are no products on the shelves, the cost of which is several times lower than the average, you should be on your guard. Now there are quite a few fakes, the quality of which can be very unpleasant to surprise not only during the installation process, which is not so scary, but also during operation. Agree, it is rather unpleasant if the pipes flow at the most inopportune moment. Although, it is unlikely that any moment for an accident can be called a suitable one.

Let's try to consider the average prices per meter of polypropylene pipes for heating in Russia.

Here are five of the main manufacturers on our shelves. But after all, pipes alone cannot be dispensed with during installation, and therefore it is worth finding out the prices for fittings. There are a lot of them, which means it makes sense to consider only the angles at 90 0 as the most demanded. The cost is indicated for a pack of 10 pcs.

Such is average cost for similar products. If we talk about those who have already replaced the usual iron pipes on polypropylene, it will not be uninteresting to look at their reviews:

Chivas, Russia, Rostov-on-Don: Two years ago, I decided on my own to make heating in the house, wiring to batteries and connecting to gas boiler, (already having a little experience in this earlier). Stopped for reinforced polypropylene for hot water Kalde is of Turkish origin, because it had something to say “at a good price”, before that it dealt with “pilsa”, but in contrast to it, “calde” is a little better soldered, and much less stench when soldering. When everything was soldered, I decided to test it for strength, so to speak. When tested under water pressure of 2 atmospheres and a temperature of +70 degrees, the pipes almost did not deform, all the adhesions remained dry, and did not bend or lead anywhere. They have been working for the second season, for a low price - I'm happy!

valer1234, Ukraine, Kolomyia: Experience with the products of this manufacturer is about 8 years. I first encountered them when I was rebuilding my house and had to change the pipes for water supply and heating. Then there was a small selection of manufacturers, but fortunately I chose these. Although at that time I did not really understand this, my intuition, along the way, did not disappoint me. When brazing, this pipe behaves very nicely - it heats up slowly and cools slowly ...

Of course, the reviews of professionals about polypropylene pipes for heating are not as enthusiastic as those of beginners, but they still admit that they are really easy to install and durable.

How to perform heating in a private house from polypropylene pipes with your own hands: step-by-step instructions with photo examples

The laying of heating lines does not raise any special questions, and therefore it is necessary to consider the soldering process itself step by step. In addition, if the welding of any polypropylene pipes different types is the same, then the preparation for this process for those reinforced with aluminum, both inside and outside, has its own nuances. We will try to designate them now.

Photo example	Action being performed
	Here is the outer layer of aluminum that needs to be removed in order for the soldering to be strong and of good quality. Otherwise, the elements will not weld together, which is fraught with leakage
	It is with such a device that the outer layer is removed.
	We put the cleaning on the pipe and turn it several times until the aluminum layer is completely removed. This is how a pipe ready for soldering should look like.
	We put both parts (corner and pipe) on a heated iron ...
	... then we press them all the way. Heating time - from 3 to 8 seconds, depending on the diameter
	After removing the parts from the iron, insert the polypropylene pipe into the corner until it stops and wait 3-5 seconds.
	After that, the connection is ready for use.
	As for the polypropylene pipe with internal aluminum reinforcement. The photo shows: on the left - external reinforcement, on the right - internal
	There is another stripping for internal reinforcement. The actions are the same as with the previous pipe, but ...
	... it works a little differently. By removing part of the inner reinforcement, such stripping allows the pipe to be soldered in such a way that water does not have access to the aluminum layer. This eliminates the risk of moisture getting between the pipe layers.

If the reinforcement is made with fiberglass, the pipe does not require any special preparation before brazing. As it becomes clear, the installation and welding of polypropylene for heating in a private house with your own hands is not a very difficult process and even a schoolchild can master it.

Important! Be very careful when working with the iron. Its surfaces are heated to high temperatures, which is fraught with burns. It is best to work with heavy gauntlet gloves.

Theoretical advice for brazing polypropylene pipes and fittings

The best solution before starting the installation work on heating in the house would be a little exercise. To do this, you need to take stock into account when purchasing the material. It is better to buy 10-15 of the cheapest fittings and 2-3 m of pipes just for this purpose. Having cut pieces of pipe with special scissors and warmed up the iron, you need to try how well the welded joints are obtained.

Important! When aligning the pipe and fitting after warming up, try to connect them as evenly as possible. Only in this case, the soldering will turn out to be tight, and the line is neat.

You should not save on polypropylene pipes by buying those that are reinforced with aluminum. Especially if there is no experience in such an installation. It is better to purchase fiberglass polypropylene pipes. They are much more convenient for welding. Also, do not forget that when heated, polypropylene expands, which means that you cannot mount the fitting point-blank against the wall. It is better to leave a gap of 2-3 cm. This will allow the pipe to "play" when heated.

Welding polypropylene pipes with your own hands, although not difficult, requires complete concentration, care and accuracy from the master. Only then will the heating be carried out as planned.

If anything remains unclear, we suggest watching a short video on how to solder polypropylene pipes:

Overview of heating installation schemes: various options for heating wiring in a private house

The main heating distribution systems in the house are considered to be one-pipe and two-pipe. Although some masters, for too large areas, also offer a three-pipe system, we will not consider it due to its complexity and rather rare use.

The simplest and most common is the one-pipe system. Its only drawback is that it cannot be used with a large number of radiators. "Leningradka" belongs to such heating distribution schemes. The problem is that if the distance and the number of batteries between the first and the last heatsink is large, then the temperature difference between them will be quite sensitive.

A slightly improved version of the same one-pipe system is a scheme called "Tichelman's loop". However, the situation completely and it does not save if the area of ​​a private house is large. In this case, a two-pipe system is used. With all its positive qualities in terms of heating, it also has a negative side - the required pipe length doubles. We talked about the schemes for installing one-pipe systems with polypropylene pipes, as well as two-pipe systems, in one of our articles.

In general terms, then, of course, it is best for a beginner to work with a one-pipe system - it is quite simple. But even if there is no experience, and the area of ​​the house is large enough, it is quite possible to mount heating with polypropylene pipes using a two-pipe system. To do this, you just need to study a little more information on this topic.

“Before starting work, it is necessary to draft a future system. This will help not to get confused in the intricacies of highways, and in the future - in a timely revision to avoid accidents. "

Only by fully understanding all the schemes of systems that exist (there are very few of them), you can decide how the layout of polypropylene pipes in the house will be arranged.

Some tips for laying polypropylene pipes when installing heating

Surely everyone understands that self-installation of heating with polypropylene pipes does not only consist of drawing up a wiring diagram and welding mainline parts. It is very important and correct to fix the pipes on the wall, under the floor or behind false ceiling... After all, everything should look aesthetically pleasing.

Important! In no case should the heating pipes overlap one another. This will significantly reduce their service life and may cause an accident.

Installation of PP pipes is carried out on plastic "clips" of the required size, which are attached to the surface using self-tapping screws or dowel-nails. There is a possibility of connecting several "clips" to each other for the convenience of the installer. Polypropylene itself is most often hidden in niches under the floor, although walls and ceilings are also a good option. The main thing is the free space around them, which will allow them to "play" during the heating process.

The information obtained from reading the articles is, of course, important. But the clearer is usually an example that you can look at. That is why we offer you to watch a video on how to assemble polypropylene pipes with your own hands using the example of hot water supply, which is almost the same:

Well, to consolidate the information received, another video about welding polypropylene pipes:

Connecting a heating radiator to polypropylene pipes and how to do it

If House master already figured out with a soldering iron and can weld a pipe with a fitting, then the question of how to connect a heating radiator to a polypropylene pipe should not arise. But still we will understand in stages.

If the line has already been brought to the place where the radiator will be installed, we hang it in place and try on how long the pipe sections are needed for the connection. We solder brass threaded fittings to them by ironing. If necessary, you can also purchase ball valves, which will regulate the heating temperature of the radiator.

For your information! Shut-off valves play another very important role. If it is necessary to replace the heating radiator, it will not be necessary to shut off the entire system. It is enough to close the supply and return, and then freely dismantle the battery and replace it.

When the pieces of polypropylene with fittings are ready, we switch them to the heating main and fasten the radiator - that's all. The main thing, before tying the heating radiator with polypropylene pipes, is not to forget to mark all the lines. This point is very important - after all, it will help in the future not to get confused during installation and routing on the collector.

Summing up

Most often, home craftsmen say that they cannot do this or that work when they are simply afraid to take on it and this - main mistake... You need to believe in yourself (not to be confused with self-confidence). Realizing that there is nothing super complicated in working with polypropylene pipes, you can easily mount any, even the most complex heating. After all, it is not the gods who burn the pots, and everyone once did it for the first time. Therefore, you should remember that the main thing is strict adherence to instructions and rules, accuracy and extreme attentiveness. It is in this case that polypropylene heating will give warmth to you and your loved ones for many years to come.

We hope that today's conversation was helpful to someone. If you still have questions, we are always happy to answer them in our discussions.

And in conclusion, one more interesting video.

Video review: how to connect a heating radiator with polypropylene:

Polypropylene pipes are popular due to the affordable price and quality of the material. The low thermal conductivity of the polymer keeps the coolant temperature. The low equivalent of the roughness of the inner walls of the pipes does not reduce the flow rate. Simple assembly technology allows you to quickly mount heating in a private house from polypropylene pipes with your own hands.

Technical characteristics of polypropylene pipes for heating

The abbreviation, with information on the operating parameters of the product, is applied to the pipe walls. Basic marking of polypropylene (PP) complies with international standards:

• manufacturer's company logo;
• letter designation and addition about product modification (PP-random, PPRC, PPs);
• nominal pressure (PN25 MPa) of the working medium;
• outer diameter and size of the product wall;
• service class;
• maximum permissible operating pressure in bar, which indirectly indicates the service life of the product;
• product standard.

Description design features, the purpose and scope of the product is given by the manufacturer in the technical data sheet of the product. The table, as an example, gives data on the products of the manufacturer VALTEC (Italy):

Products with an inner insert of aluminum foil are used mainly for heating. Reinforcement of polypropylene pipes with fiberglass also allows their use in radiator circuits, warm floors and hot water supply for private houses. However pipes with inner layer fiberglass fibers allow slight elongation of linear sections when heated and oxygen permeability.

Technical characteristics of reinforced polypropylene pipes (manufactured by VALTEC):

Fittings and valves for heating systems made of polypropylene are made of a random copolymer similar to the material of pipes. Non-threaded elements are designed for socket connection, in which the pipe is inserted into the body of the fitting. The inner diameter of the fittings (90 ° and 45 ° angles, couplings, adapters, tees, crosses and taps) corresponds to the outer diameter of the pipe. Linear thermal expansion is offset by ready-made expansion joints or self-made welded structures.

Clamps (single and blocks of clips) are intended for fastening straight, horizontal or vertical sections of the pipeline along the walls. The step of installing the fasteners (recommended by the manufacturer) depends on the size of the pipe and the quality parameters of the coolant. Clamps from similar raw materials are intended for fastening PP pipes large diameter... The mount can be rigid or floating, a small clearance will allow for free play during thermal expansion.

The connection to steel pipes or fittings is obtained using combined fittings. Collapsible fittings (American) for the transition from metal to polymer are produced with an internal or external thread made of galvanized metal on one side, and a propylene insert on the other.

A set of fittings and fittings is selected individually for each room in the house. The number and brands of fittings depend on the configuration of the heating system and the type of heating equipment.

Price of propylene pipes for heating

The cost of the product depends on the purpose and manufacturer. Well-known domestic manufacturers specializing in the production of reinforced PP pipes: Sinikon and YarInterPlast.

PP pipes of the PN25 MPa brand are used for heating. The price of polypropylene fiberglass-reinforced pipes is lower than products with an internal aluminum frame (by about 10%). The difference is explained by the guaranteed service life of the product, the permitted temperature of the heating medium and the operating pressure of the system.

Average cost of polypropylene pipes for heating (price per meter):

According to the reviews of professionals, polypropylene pipes for heating - the best option autonomous systems. Homogeneous brazed construction without threaded connections and metal fittings is easy to install and convenient to operate.

Polypropylene pipes in the water heating scheme of a private house

The piping transmits the flow of heat energy from the boiler to the heating devices. Water is a traditional heat carrier of heating systems for country houses... The amorphousness of the polymer to an aggressive environment under the influence of high temperatures is the key to the durability of pipes. The inner surface of the pipes offers negligible resistance to directional flow. The impurities contained in the coolant in suspension (organic matter, compounds of hardness salts, scale, sand particles) do not form deposits on the walls of polypropylene pipes. Aluminum-reinforced products exclude the access of oxygen to the heating system from the pipeline. A layer of foil-clad metal reduces the risk of corrosion of the boiler heat exchanger, increases the service life of the system as a whole. Numerous materials, diagrams, videos of DIY heating in a private house can be easily found on the Internet.

Emergency freezing of piping does not threaten the destruction of polypropylene pipes. After defrosting the water, the material restores its original properties. However, it should be remembered that it is impossible to heat PP pipes with an open flame!

The increase in the linear dimensions of the pipe during heating is perhaps the only significant drawback of polypropylene products. Reinforcement with aluminum foil significantly reduces the rate of thermal expansion and increases the level of class of pipes.

Considering that the optimal pressure in the household boiler circuit is 1.5? 2 bar, the heat source is as close as possible to the consumer and the temperature in the residential building does not fall below 5 ° C, we conclude: polypropylene reinforced with aluminum is an ideal material for piping in a private house.

Resistance heat welding production rules

Installation of polypropylene heating systems is carried out at a room temperature of at least 5 ° C. Consumables for heat sealing (accessories) must correspond to the purpose (PPRS).

The sequence of operations in the manufacture of units at the place of work:

• pipes are cut with special scissors according to preliminary markings on the body;
• preparation of the cut surface includes chamfering to a depth of 1 mm at an angle of 30 ° and degreasing the pipe end with acetone;
• marking the boundaries of the melt - a restrictive risk is applied to the end of the pipe with a pencil;
• processing of the working surfaces of the soldering iron;
• heating the tool;
• melting of parts (with holding time ranges of pipe diameters according to the instrument passport, and the alignment of parts with the iron body);
• docking of a node without displacement and rotation of elements;
• cooling.

The size of the embedded section of the pipe for heating:

Time schedule for the manual thermal welding process (standard values):

The voltage of the electric current in the soldering iron for polypropylene is 36V. The operation of the tool from a household network requires circuit breaker disconnection.

After cooling of the joints, check the straightness of the joint, the uniformity of the bead of the welded seam and the absence of welding defects. The number of connectors, when the rules are followed contact welding does not affect the system bandwidth. Low resistance in welded parts due to physical properties material and connection method without reducing the flow area of ​​the pipe. Hydraulic tests for strength and density of the PP pipe system are carried out 16 hours after welding.

Polypropylene water heating schemes for a private house

A non-volatile or pressure head, one- or two-pipe scheme is chosen based on considerations of efficiency and comfort. Traditionally, private houses are equipped with horizontal wiring with independent floor contours. Heating system small houses with natural circulation is a chain of serial connection of radiators. Efficient heat supply at home large area carried out by two-pipe wiring with forced movement of the coolant.

High-quality installation and piping of equipment is impossible without calculating the throughput and determining the diameter of the pipes at each section. The coincidence of the calculated and actual costs will reduce heat losses, will ensure stable, reliable and quiet operation of the system.

With the help of an online calculator, you can do a hydraulic calculation for a one-pipe water heating scheme for a private house with your own hands. DanfossCO and OvertopCO software provide calculations for in-house heating systems with natural circulation. Calculations in Excel Online are summarized in a convenient tabular form. By filling in the initial data column and choosing the necessary constants (the columns are highlighted in color), we obtain the calculation results.

The classic method of arranging a heating system is one-pipe wiring. The installation can be explained by a thematic video of heating a private house made of propylene. With your own hands, you can quickly, accurately and cheaply perform equipment strapping.

Single-pipe systems with natural circulation operate under the influence of gravitational forces. A slope when laying pipes and installing the heat generator below the level of the living quarters will increase the flow rate. However, when radiators are connected in series, it is impossible to evenly distribute the heat. The rooms located far from the boiler warm up poorly, there is a danger of stopping the circulation and boiling of the boiler water.

The problem is solved by the device for heating a private house with your own hands in the "Leningrad" scheme. Videos can be found online.

The removal of the nozzles to the heating devices divides the flow, most of the coolant continues to flow through the system. The flow through the radiator is controlled by installing a thermostat valve, diagonally connecting the device or changing the bypass flow area.

The main components of heating are a heat generator, pipes and heating appliances. The rest of the equipment ensures the performance of the system under various loads. The equipment of the system with additional elements depends on the size of the house and the modification of the selected boiler. The set operating parameters of the unit are provided by a safety group, an expansion vessel with an overflow pipe, a blower and a pressure regulating device.

If the circulation pump is not built into the boiler circuit, then the blower is installed on the return line of the pipeline, in the immediate vicinity of the heat generator. The installation location of the closed-type expansion tank for heating is in front of the circulation pump. The safety group is mounted on the supply line near the boiler.

The concept of comfort is individual for each person. But for everyone, without exception, home is warmth. Heating is an integral part of any home. Make a smart decision and implement it on their own maximum awareness in this topic will help.

The thick steel pipes of heating systems in private homes are familiar to many. In addition to them are no less thick and heavy cast iron batteries... During overhaul it is customary to change them for more modern models- plastic pipes are laid in houses and compact aluminum or steel batteries are installed. In this review, we will talk about plastic pipes ah and consider the heating schemes in a private house made of polypropylene.

Advantages and disadvantages of polypropylene pipes

Metal pipes are used less and less in autonomous heating systems. Their place is taken by brothers made of polypropylene. They are easy to install and resistant to high temperatures. Pipes can be easily soldered and cut, and no less easily laid directly into walls or floors. In the event of a breakdown, it will take a minimum of time to replace the damaged area. If the installation is carried out from scratch, then when using polypropylene pipes, the terms of work are significantly reduced.

There are various sizes of PP pipes. The diameter is selected based on the power and size of your heating system.

What are the advantages of polypropylene pipes?

• Sufficient strength to work in autonomous systems - plastic pipes can withstand pressure up to 10 atmospheres and above, without bursting under its influence;
• Resistance to high temperatures - combined pipes made of plastic and aluminum are capable of operating at a coolant temperature of up to +95 degrees. A short-term excess of the maximum possible temperature is also allowed;
• Excellent passage of the coolant - the inner surface of the plastic pipes is very smooth, so nothing interferes with the flow of the coolant;
• No corrosion - if steel is afraid of rust, then plastic is not afraid of it. They do not deteriorate and do not rust, retaining their properties for many decades;
• Long service life - manufacturers assure that polypropylene pipes serve for 40-50 years and even more;
• Resistance to salts and aggressive components - polypropylene reacts calmly to the increased acidity of the coolant, without collapsing or deteriorating;
• Ease of installation - the heating system can be easily assembled by yourself, without any outside help.

The list of advantages is quite large, which is why polypropylene pipes are so widespread.

Long service life is achieved by observing optimal conditions operation without overloads in pressure and temperature.

Unfortunately, polypropylene pipes also have disadvantages:

• The presence of heat loss - you will have to pay for this with additional heating costs... In some cases, the problem is solved with the help of additional thermal insulation applied on top;
• Need to learn correct installation- those who are used to working with metal pipes will have to learn the principles of their installation from polypropylene.

Also, for the installation of pipes, you will have to purchase special equipment for soldering. We recommend contacting heating and plumbing stores for equipment rental - many stores give "soldering irons" for rent, with daily payment, which will provide additional savings.

Choosing polypropylene pipes

Polypropylene pipes for heating have an aluminum layer in their design for greater resistance to high temperatures.

Conventional plastic pipes are not suitable for heating - the high temperature of the coolant can damage them. Therefore, heating systems use reinforced pipes. They contain aluminum or fiberglass in their structure, which makes them stronger and more resistant to high temperature... Such products are perfectly suited for use in heating systems.

When choosing pipes made of polypropylene, you need to pay attention to the manufacturer. The best option is buy products from the most common brands, of which there are not so many. Taking the products of a little-known manufacturer, you may be faced with a situation of lack of suitable fittings and other accessories - if something breaks in the system or requires its alteration, installation and renovation work may drag on until the desired items are found.

For the installation of pipes, it is advisable to use one-piece fittings - they provide a strong and tight connection. Installation work is carried out using a special soldering tool.

Heating scheme in a private house

In private homes, a one-pipe heating system with a circulation pump is often used.

Heating schemes in a private house, with polypropylene pipes, can be very different. For example, nothing prevents the laying of a one-pipe system, supplemented by a circulation pump - it will provide an intensive flow of the coolant and uniform heating of the premises. It is possible to use vertical two-pipe systems with bottom and top wiring. If you want to do a horizontal layout, please.

Thus, in private homes, a wide variety of heating schemes are used. They warm up the premises well, but it is highly desirable to use in them circulating pumps ... This ensures normal circulation of the coolant.

Installation of polypropylene pipes

A special apparatus is used for soldering polypropylene pipes.

For the installation of polypropylene pipes, special tools and fittings are used. The soldering tool welds the products tightly, forming a reliable and sealed connection. Cutting is carried out with an ordinary hacksaw for metal or with the help of special scissors - this equipment can be rented. When cutting pipes, ensure that the angles are observed.

Since there is an aluminum reinforcement inside the plastic pipes for heating, the edges must be cleaned after cutting - use a suitable sandpaper. Hot pipes and fittings are connected to each other while hot, and the junction must remain motionless during cooling - distortions are not allowed here. If you need to ensure the joining of plastic and metal pipes, use special fittings for this.

The correct use of modern component parts in construction helps to improve the economic and operational characteristics of various engineering systems... Durable can be made quickly and inexpensively. How to choose the best products and complete assembly work without errors, described in this article.

What are the advantages of propylene pipes and what are the disadvantages to remember

The exact data on prices are given in the corresponding section of the article. But it should be noted right away that polypropylene pipes are cheaper compared to the use of similar ones, copper. It is also necessary to consider the following significant advantages:

• The low weight of polymer products simplifies handling and assembly operations. The installed system will not put too much stress on the structural frame of the building.
• Polypropylene is a chemically neutral compound. It does not pollute water and environment, is not destroyed by corrosion.
• Typical products made of this material remain intact at a liquid temperature of + 80 ° C or more. This is quite enough for the full functioning of individual heat supply systems.
• Scale particles are not retained on the smooth inner walls. Their attachment also blocks a change in size with a decrease / increase in the temperature of the coolant.
• Such products are not damaged by mechanical impurities, electrochemical forms of corrosion.
• They are able to perform their functions for tens of years without clogging the working channels.
• The thick walls and special structure provide excellent insulating properties. Even with a high head, polypropylene does not generate a lot of noise. Condensation does not form outside.
• The polymer pipe will retain its integrity after repeated cycles of freezing and thawing. This property is especially useful when equipping stand-alone real estate objects, as it prevents accidents.

The development of a draft design is carried out taking into account general principles systems for a specific object. The use of installation of a one-pipe heating system with polypropylene pipes will save materials and labor resources. However, such solutions are rarely used these days. In a private house, it is more convenient to install several independent circuits to meet different needs.

The two-pipe method provides equal head in, which increases the accuracy of their work when equipped with the appropriate. B can be set, since it implies an operation mode with a relatively low coolant temperature.

From correct selection battery life depends entirely on the long-term operation of the entire system and its efficiency. will suggest an analysis of individual models and characteristics of equipment in this article.

A similar comprehensive assessment can be applied when considering a fluid transportation system. The water is moving too slowly by gravity, you have to maintain an optimal slope on long horizontal sections. In compulsory, the pressure increases, which will have to be taken into account when choosing pipes.

In the technical and economic part of the professional project, the estimated costs are given, and the work operations are described. At this stage, you can make the necessary changes to the drawings and parts lists. After the final approval, a package of working design documentation is produced.

Its preparation can be entrusted to professionals, or you can do all the necessary actions yourself. In any case, you need to create a sketch and a list of component parts. But detailed description these procedures are beyond the scope of one feature article. Therefore, we will focus directly on the installation of heating from polypropylene pipes.

To determine the correct fastening methods, the following essential features should be noted. The table shows data on the linear change in the length of a section of the pipeline (10 m) with an increase in temperature of 45-55 ° C:

This information means the need to take into account changes in the linear dimensions of products during operation. When placing a pipeline with an outer diameter of up to 20-25 mm inside a thick concrete screed (the distance to surfaces is more than 3 cm), no additional measures are required. Otherwise, use damping pads made of suitable materials create special channels. When passing through the walls, embedded pipe sections are used to create a hole of sufficient diameter.

Correct routing of polypropylene pipes on open areas is performed using the following compensation schemes:

Important! For accurate calculations of these nodes, data on the linear expansion of polypropylene pipes are used, taking into account the actual operating temperature range.

	After that, parts (pipe and) are inserted, taking into account the different configurations of the dies. Products do not rotate during heating. The operation time depends on the diameter of the part to be connected.
	Further - the parts are removed from the dies, carefully connected. The alignment should not be disturbed, rotation should be excluded. The created connection is monolithic. It does not need to be serviced during its entire service life.

When installing heating lines from polypropylene pipes with their own hands, the methods discussed above are used. In strong concrete, no additional measures are applied. In open areas and when passing through walls, thermal expansion is taken into account, expansion joints are used, and a sufficient distance is left to the nearest parts of the structures.

Here the master talks about the installation of polypropylene pipes with his own hands in the video:

Here, the use of such tools for cleaning foil before welding propylene pipes is discussed in detail in the video: it is directed along a detour (1). If the valves (3) are closed, the product can be dismantled for replacement or repair.

By using detailed instructions, photo and video materials are not too difficult to perform the necessary work steps without errors. Nevertheless, any theoretical knowledge must be tested in practice. To acquire the necessary skills, it is better to practice in advance. This will help create truly reliable connections. Special care should be taken when installing the pipeline inside building structures where there is no free access.

In the comments to the article, ask questions, leave your comments, give examples of high-quality and defective products. Such communication will help eliminate erroneous actions, increase the likelihood of successful solution of practical problems.

The topic of reliability, efficiency and durability of the heating system of private houses in our country will always be relevant due to climatic conditions. Therefore, homeowners have to wonder how to achieve this with minimal cost financial resources and time.

Heating system made of polypropylene pipes in a private house

To do this, at least the following conditions must be met:

• competently draw up a project for the location of the main elements of the heating system in the house;
• choose quality equipment, tools and pipes;
• plan the sequence of installation work;
• if possible, do all or most of the installation yourself.

Rich long-term experience in the operation of steel pipes and cast iron radiators indicates the difficulties in these heating systems during installation and operation. The main disadvantages include the large weight of all elements, which complicates installation work and contributes to the clogging of pipes with scale products and rust. Gradually, people are moving away from these ancient technologies.

It is very practical to use a heating system with copper pipes, it does not rust, therefore it is durable, but very expensive. Everything more people tend to use polypropylene pipes. Let's consider this option.

Advantages

• In heating systems, one of the advantages of polypropylene pipes is high thermal insulation. This ensures low heat loss on the way to the radiator, less fuel is consumed for heating, and higher efficiency.
• In terms of service life, polypropylene pipes are superior to metal products. Some manufacturers claim that their products will last at least 50 years.
• Installation technologies are well thought out and worked out in practice. They are simple, do not require heavy, welding equipment, gas cylinders, hoses and transformers. Installation of polypropylene elements can be compared to a children's designer, only for adults. All products and tools, simple and light, are appearance it is intuitively clear what and where to attach. A person who does not have special professional skills can assemble everything with his own hands with high level quality.

Installation technologies for polypropylene pipes

• The elasticity of the material makes it possible to better tolerate the freezing process in comparison with metal products.
• Polypropylene parts do not rust and do not have scale during operation. The pipes are neutral to the chemical components of the coolant, do not enter into a chemical reaction with it.
• The cost of polypropylene products is significantly cheaper than metal and especially copper.

Disadvantages and methods of their elimination

• The main disadvantage of polypropylene pipes is considered to be a large coefficient of expansion. At a coolant temperature of 100 ° C, 10 meters of the pipe is lengthened to 15 cm. This leads to deformation of the structure. In order to prevent destruction, flexible supports are placed and compensation loops are made. Later, pipes reinforced with foil began to be used, which significantly reduced the coefficient of expansion. Nowadays, the most practical pipes are fiberglass-reinforced: under the same conditions, they lengthen by only 1 cm.
• Polypropylene products, especially connecting elements, are inferior to metal pipes in strength. It is not even correct to compare them: under strong impacts with hard objects, polypropylene deforms and can collapse.

Choice

There are many models of polypropylene pipes. Let's describe what can and should be used.

A mandatory requirement for a heating system is that only heat-resistant pipes and connecting elements are selected that can withstand temperatures of at least 80 ° C.

They must be reinforced; there are three types:

• outer diameter pipes reinforced with PPV foil;
• inner diameter pipes reinforced with PPV foil;
• PPV pipes reinforced with fiberglass.

Reinforcement of the pipe with foil along the inner diameter

The most the best option glass fiber reinforced pipes are considered; they are well soldered and have a low expansion coefficient. Pipes reinforced at the outer diameter must be stripped of reinforced foil at the joints before soldering. These are unnecessary problems and the likelihood of deformation. All of these options must withstand a pressure of 6-7 atmospheres.

Correspondence table of pipe parameters

Couplings, swivel fittings, valves should preferably be used without metal elements. The connections are made only by welding, while both ends are inserted into the coupling - this is the most reliable and durable connection.

Control Valves: Couplings and Fittings

It is recommended to buy pipes and all component parts of European manufacturers, for example, Germany, Czech Republic. Turkish production is still far from perfect: uneven reinforcement layer and wall thickness along the outer and inner diameters.

Mounting

If you need to do a high-quality installation with your own hands, you should start by drawing up a detailed diagram indicating not only the locations of the main elements, but other parameters:

• pipe laying routes;
• places of connections, turns and connections;
• pipe diameters;
• the number and locations of couplings, fittings and valves.

Heating laying scheme in the house

The pipes of the common line are selected with a large diameter, and the outlets to the radiators have a smaller diameter.

Based on these data, you can accurately calculate what needs to be bought and what consumables and tools will be required.

For a private house, the best option for assembling a heating system is considered to be "Upper Spill" - a gravity-flow scheme. It is simple, available to do it yourself. There is no need to install forced pumping pumps to circulate the coolant fluid. It is not necessary to increase the diameter of the common line pipe, this will only slow down the circulation and increase the heating costs. The optimum diameter for these purposes is 63 mm.

After purchasing all necessary materials installation is in progress. It starts with cutting pipes with special scissors according to pre-calculated dimensions. Then the pipes are laid out according to the laying route scheme. It is important that the ends on the cuts are at 90 degrees.

The soldering apparatus must be placed horizontally on the surface, with a degreased nozzle selected according to the size of the pipe. We heat it up to 360 ° C. At the same time, the connecting surfaces are heated in the working hole of the soldering iron. Then we insert the pipe into the fitting.

The parts must be heated to room temperature before soldering. If you solder a fitting brought from frost, the structure of the plastic will be broken from a sharp temperature drop. Such a connection will not last long.

The soldering points on pipes and fittings must be thoroughly cleaned and degreased, you can use vodka or alcohol with water 1: 1. At the end of the work, it is required to make a connection: fill the system with water and check the operability for two hours at a maximum temperature of up to 90 degrees.

• scissors for cutting polypropylene pipes;
• electric soldering iron with nozzles for welding polypropylene pipes;
• puncher for drilling vias in walls;
• tape measure, marker;
• pipes, couplings, fittings, adapters, crosses, all according to the previously compiled list.
