Fastening polypropylene pipes. Polypropylene pipeline installation rules Designing heating from polypropylene pipes SNiP

The pipeline is fixed to different surfaces (floor, wall, ceiling) by means of special fasteners. They are clamps that clamp the pipe in diameter. A distinctive feature of this device is considered to be its reliable attachment to the wall. In addition to it, bolts are needed with nuts.

Types of fasteners

Mounts have several varieties:

• crimp;
• safety;
• guides;
• reference.

They are needed to fully attach fastening to the pipeline in different places.

Clamp is made of steel or plastic. There are fasteners having a rubber seal. The device may be dismantled if it is provided for by its design. Such a clamp is called split.

Important moments

1. The deviation of the pipes in the vertical position should not exceed 2 mm (by 1 m length).
2. Clamp can not be placed on the plot, where the pipelines are joined to each other.
3. When bringing fixtures, it is strictly forbidden to use wood tubes and welding.
4. Tubes of risers in industrial buildings are attached every 3 m (by SNU). SNiP is a combination of regulatory acts dedicated to construction.
5. Pipes of risers in residential buildings are fixed if the height of one floor is over 3 m. It concerns pipelines made of steel.
6. The sewer pipes from plastic should be strengthened, not forgetting about the bias.

Before you finally install the clamps, it is necessary to calculate compounds with nozzles, the exception is soft types of fixation. Rubber rings are used for junction compounds. The nozzles of the compensation species use only once.

The gap between the attachments of polypropylene tubes is calculated during the design. This step is associated with rigid fixation provides longer operation. In this situation, it is necessary for the way that there will be fasteners, in the design of which there is a rubber gasket.

The distance between the attachments of polypropylene pipes on the SNIP directly depends on:

• temperature regime of the distiluate substance;
• content in the wall of the pipe of aluminum or fiberglass;
• linear expansion coefficient in a polypropylene pipeline;
• thickness, diameter and material manufacturing material;
• additional loads.

Ignoring these factors will adversely affect the life and capacity of the pipeline. With too much distance between the fasteners there will be pinned down and the flexing of polypropylene pipes, which will lead to the destruction of the entire system.

It is quite difficult to calculate the distance between the clamps for PVC pipes. To facilitate this task, building materials manufacturers are applied to its products (polypropylene tubes) instructions for use, which contains an explanatory table (calculation depending on the diameter of the pipe and temperature fluid temperature mode). Example in the photo.

If a firm is reliable, then the technical catalog is present in public access. In the absence of information about the distance between the fasteners, professionals are advised to make small gaps between the clamps.

This method has two drawbacks:

1. Installation of polypropylene pipes will take longer than previously provided.
2. We will have to purchase a number of additional clamps.

The design of the sewage pipeline is carried out taking into account the relevant regulatory documents (SNiP). Fastening will be needed, without them the sewer system will not function normally, as its alignment will disappear. In this case, not only the clamp is used, but also a plastic clip.

In the first case, the material from which the pipe is made does not matter (iron or PVC). In the second except the clips itself need a dowel. If the sewer pipe has a PVC, then its diameter will not be large. The reason for this is that plastic is not intended for too much load. Size clips varies in a period of 16-50 mm. It does not apply for fastening the pipe to the floor.

Steel or iron sewer pipes do not change under the influence of high temperature, which you can not say about those manufactured from PVC. Such a process compensate for a clamp. At the same time use both rigid and floating method.

The distance between the PVC sewer pipes fasteners is determined by the sewage system plan. Fasteners are carried out by applying the minimum gap. The frequency is 40 cm with a diameter of 50 mm. Further indicators increase proportionally, for example, if the diameter is 100 mm, then the distance from one attachment to another 80 cm.

Similarly, the installation of the pipeline on the ceiling is carried out, it is usually carried out in the basement. Fastening in the form of clamps to use on bends is prohibited, there must be a distance of 1.5 dm. Fix the docking fitting and pipe must.

Fastening of steel pipeline

The distance between the fasteners of steel pipes on SNiP depend on the diameter. If the conditional pass reaches no more than 20 mm, then the gap between the clamps should not exceed 2.5 m. With diameter up to 32mm - 3m.

For a hole, the radius of which is 40mm, it is necessary to take a distance equal to 4 m. When opening the steel pipeline, clamps and brackets will be created by the wizer. The use of welding (gas or electrical) is strictly prohibited. Steel pipelines laid by a trenchless way are not considered operational.

The quality of the work performed is influenced by the selected materials and exact following the developed pipeline plan. If necessary, you can consult with professionals. Their recommendations will help you choose fastenings suitable for pipes, and produce their competent installation. Do not neglect the experience of specialists.

Possessing many years of experience in solving problems with the configuration and construction of facilities, we suggest you to get acquainted in our directory with prices for pipes from polypropylene and additional products from polypropylene.

Installation of polypropylene pipes in Russia is regulated by the provisions of GOST R 52134-2003 "Pipes pressure of thermoplastics and connecting parts for them for water supply and heating systems", SNiP 41-01-2003 "Heating, ventilation and air conditioning", SNiP 3.05.01-85 " Domestic sanitary and technical systems ", SNIP 2.04.01-85" Internal water supply and sewage system "and SP 40-101-96" A set of rules for the design and installation of pipelines from polypropylene "Random copolymer". In the European Union, the requirements for the installation of polypropylene pipes establish a number of technical regulations - standards, a detailed list of which is given in this material.

The main purpose of the installation of polypropylene pipes, regardless of the source material (polypropylene homopolymer PR-H, PR-B polypropolymer block copolymer, PPRC polypropylene randomsopolymer) and its modifications (Polypropylen-Homopolymer PP-HS Fire-resistant, Polypropylen-Randomcopolymer PP-R-EL electrically conductive, Polypropylelen -RandomCopolymer PP-RS-EL electrically conductive and fire-resistant) (see more detail), as well as reinforcement by aluminum foil or glass fiber is to ensure operational conditions under which the pressure and temperature of the transported fluid, and the ambient temperature will not be caused in the pipeline and its individual nodes of the internal Stresses capable of impaired integrity or residual deformations in pipes, fittings and connections. The priority of the installation of polypropylene pipes remains compensation of linear temperature changes in the pipeline by changing the direction of the route and without the use of special compensators.

In contrast to pipes from galvanized or stainless steel (see), all pipes from polymer thermoplastics (see this material) have a high coefficient of linear temperature expansion, especially significant in hot water and heating systems.

To solve this problem, the pipeline route is conditionally divided by fixed supports to the sections that autonomously react to changes in temperature (or pressure) in the pipeline. Still supports (but) send an extension along the axis to sliding supports (CO) installed in the locations of the direction of the route, which are essentially compensating devices.

The relative temperature elongation of the pipeline section bounded by fixed supports for polypropylene tubes is calculated by the formula ΔL \u003d 0.15 * L * ΔTWhere:

• ΔL. - change of linear size of the pipeline section along the axis of the track, mm;
• l. - length of the pipeline, limited by fixed supports, m;
• Δt. - the difference in the temperature of the pipeline during operation and during the installation of polypropylene pipes, ° C;
• 0.15 - The coefficient of linear temperature expansion of polypropylene pipes, mm / m ° C.

Important: Polypropylene pipes reinforced by aluminum foil have a temperature linear extension, 2/3 less than polypropylene pipes without reinforcement. Polypropylene tubes reinforced with fiberglass have a temperature linear expansion, 3/5 less than polypropylene pipes without reinforcement.

Linear temperature expansion of PN 10,16.20 pipes from polypropylene randomsopolymer and PP-R polypropylene-reinforced polypropylene pipes for hot water and heating systems, depending on the temperature of the transported medium, can be determined by nomograms (see below).

Fig. The nomogram of the linear temperature expansion of pipes PN 10,16.20 from the polypropylene randomsopolymer depending on the temperature of the transported medium

Fig. Linear temperature expansion of PN 20 pipes from polypropylene randomsopolymer reinforced by aluminum foil, depending on the temperature of the transported medium

Sliding supports when installing polypropylene pipes, as a rule, are performed from clips, single or doubles corresponding to a diameter Dn with a nominal diameter of the polypropylene tube.

Fig. Single and double clips for sliding pillars from polypropylene

SP 40-101-96 categorically prohibits rigid fixation of the pipeline when installing polypropylene pipes by compressing the pipeline. Therefore, fixed supports can be performed on the basis of sliding supports with the restriction of axial movement with two couplings or coupling and a tee.

Fig. Fixed support for the installation of polypropylene pipes according to the recommendations of the SP 40-101-96

Most commonly, when installing polypropylene pipes, use compensating changes in the direction of the route:

The possibilities of loop compensating elements depending on the nominal diameter of polypropylene pipes are presented in the table below.

d, mm.	16	20	25	32	40
ΔL, mm.	85-90	80	65-70	55	45

Important: The loop compensating elements have drawbacks - when installing on the horizontal and vertical tracks of the pipeline, it is extremely difficult to remove water, and when installing in horizontal tracks - air.

When installing polypropylene pipes, sliding supports are installed on the sides of the turns, tees and taps, and all types of compensating devices can be used for cold / hot water pipelines and heating.

SP 40-101-96 places strict requirements for:

Nominal outer diameter, mm	Temperature of the transported environment, degrees Celsius
	20	30	40
16	500	450	400
20	550	500	450
25	650	550	500

Compounds performed when installing polypropylene pipes

The main types of compounds in the route when installing polypropylene pipes are attributed.

Polypropylene today is the most sought-after material with the arrangement of pipelines for hot / cold water. One of the most important conditions that ensure reliable operation of the system is the correct fastening of polypropylene pipes. It can be performed in several ways that are divided into two main groups: external installation and internal.

Regardless of the selected installation option, it will require special fastening elements and "consumables". This review presents topical information that will be useful when choosing fasteners and consumables required for the arrangement of polypropylene highways.

What are the standards for fastening polypropylene pipes

The gasket of polypropylene pipelines must be performed in accordance with the standards specified in GOST 52134-2003. This standard presents all the necessary requirements for the fastening of pressure pipes from polypropylene. Compliance with this standard guarantees reliable operation of systems and lack of leaks at normal operating parameters (temperature \\ pressure) in the system.

The pipe mount must be performed in such a way as to compensate for their thermal expansion. To solve this problem, fixed elements of the sliding fastening are used, which are capable of reacting to temperature differences (single \\ double clips).

The construction of construction rules 40-101-96 indicates the inadmissibility of the rigid fastening of polypropylene pipes. Therefore, it is necessary to use fixed elements of a sliding fastening that compensate for linear extensions.

How is the fastening of polypropylene pipes

For mounting highways using pipes from polypropylene, you will need:

plastic clips (or clamps) of the desired size;

• dowels.

2. Tools:

• screwdriver figure;

  knife \\ scissors for cutting polypropylene pipes;

  yardstick;

• pencil or marker.

Polypropylene pipe fasteners should be carried out taking into account the risk of mechanical deformation and thermal expansion of the highway. Specialists are recommended to carry out pipes in strokers, suspended ceiling structures, walls, in tie, along the walls under plinths or in an open way.

The installation of propylene pipes must be performed at ambient air, not lower than + 5 ° C.

Pipes with an outer diameter ranging from 16 to 32 mm should be bent with a radius that is at least 8 outer diameters. Perform such operations at an air temperature of more than 15 ° C.

Propylene pipes must be protected from exposure to an open flame.

If during the wiring process there is a need to cross the pipelines, then it is necessary to use special mounting parts for intersecting.

When connecting pipes using threads, special fittings of the desired size are used. Cutting threads on the polypropylene tube are prohibited.

If plots made of metal pipes are present in the polypropylene pipeline, the compound must be performed without the use of soldering or welding, as this can lead to overheating of polypropylene fasteners.

Laying pipelines is performed with a slope of at least 0.5%. At the lowest point of the pipeline, it is necessary to provide a drainage crane or drain valve. Long pipelines should be divided into separate elements that can overlap with ball-type cranes or passage of shut-off valves. This is necessary to simplify the maintenance and repair of the polypropylene pipeline. At points where the installation of mixers and other plumbing equipment is planned, a universal wall mounting is installed with an axis adjustment from 10 to 15 cm.

Distance between fasteners

Maximum polypropylene pipe fastening step PN 10. For horizontal highways:

Distance between polypropylene pipes PN 16. When the horizontal laying should not exceed the values \u200b\u200bthat are listed in the table:

Distance attachment of polypropylene pipes PN 20. (The maximum interval between supports) when horizontal installation should not exceed the following values:

With a vertical attachment, the values \u200b\u200bpresented in the table must be multiplied by 1.3.

For polypropylene pipes Stabi PN 20.with reinforcement:

Methods for fastening polypropylene pipes:

	At points where it is necessary to perform a highway
At the attachment points of the reinforcement	Using Khomutov
	Fastening next to the fitting

By performing the fastening of polypropylene pipes, the operating conditions should be taken into account (temperature \\ pressure), permissible linear extension, as well as connectivity options. There are two main mounting options:

still (there is no possibility of moving fastening along the axis of the polypropylene tube);

movable (compression is provided \\ stretching the highway without changing the position of the axis).

When it is better to use clips for fastening polypropylene pipes

Nylon clips are used for mounting pipelines from polypropylene. These parts have the necessary resistance to high temperatures and durability. The size of the clips must be seamlessly based on the pipe diameter (outdoor). The fastening of polypropylene pipes is performed in accordance with the installation requirements. Advantage of mounting pipelines with clips:

Fast and reliable pipeline laying. Fastening the clips to the wall or other surface is performed by self-drawing.

This mounting option can be used for laying high-end polypropylene pipes, which operate in a wide temperature range.

• When complying with the requirements of installation (clips installation intervals), the lack of curvature of the highway during operation is guaranteed.

Fastening polypropylene tubes with clips provides aesthetic type of pipeline without additional closing structures.

Fastening can be performed without special devices and tools.

Clips for polypropylene pipes are used for fastening water supply and heating highways. With their help, you can make the fastening of the highway to the surfaces of wood, drywall, concrete or bricks. In the manufacturers catalogs, single and dual clips are presented. With parallel fastening of pipelines, depending on the distance between the mains, two single or one double clips are used. Single fastening elements are easily attached to each other without special devices. So you can install several parallel branches made of polypropylene pipes.

Clip sets can be equipped with straps that protect the loss of the pipe from the attachment.

By installing high polypropylene pipes, it is necessary to observe the mounting interval. When installing a clip on an overly large distance between the supports, the pipeline can occur. The optimal intervals of fastening for pipes of different sizes are presented in the table:

Table 1

Before performing work on the attachment of polypropylene pipes, they must be combined with each other. To do this, the butt, polyfuzny welding or connection of the electrophing. In order to quickly and efficiently perform the installation of the pipeline, the specialists are recommended to be guided by the following algorithm of actions:

Prior to the start of installation work, it is necessary to place the future highway around the perimeter. It is necessary to provide a small bias of the pipeline.

At the attachment points of the highway, you need to drill holes under the dowel.

In the holes to install clips.

Using a hammer and screwdriver to install a dowel.

Run the clips.

When it is advisable to apply clamps for fastening polypropylene pipes

On the attachment of polypropylene pipes, the price depends on the fastening elements used and the pipe weight. For heavy pipes of large diameter, it is necessary to use fastening clamps. These elements have a gasket from rubber, which extinguishes vibration and screw ties for reliable fastening. The clamps firmly fix even very heavy pipes with strong oscillations. In the kit there is a hairpin and dowel. Plastic or metal clamps are presented on the market. Specialists are recommended for laying polypropylene pipes to use plastic fasteners, which will ensure the same strength characteristics of the structure. The fastening of the pipeline is performed as a rigid or floating design:

For hard installation, the clamps must be tightened as much as possible on the pipes. Such an attachment is used at the points below the termination. This assembly eliminates any highway offset.

• Fastening the floating method involves a loosely tightening of the clamp. At the same time, a gap remains between fastener and the polypropylene tube. This ensures the necessary mobility of the highway at temperature linear extensions.

Specialized stores contain clamps for polypropylene pipes with a rubber gasket or without it. The presence of a rubber sealer provides sound insulation during the operation of the highway and protects it from vibrations.

Performing floating fastening of polypropylene pipes to the wall, the distance between the clamps must be selected on the basis of the diameter of the pipe. Regulatory values \u200b\u200bfor different destination pipelines are shown in Table 2.

How to fasten the polypropylene heating and water pipes with a hidden way

To solve design tasks, it is often necessary to have a hidden gasket of communications. When using polypropylene pipes, customers have doubts how reliable the pipeline will be and for what technology it is necessary to make installation work.

Polypropylene products are distinguished by stability to corrosion processes and chemically active substances. Knowing these characteristics, it can be said that the pipes from this material are quite suitable for hidden editing in the wall or in a concrete tie. Given the temperature expansion, when laying a hidden way of hot water pipelines around the polypropylene tube, it is necessary to leave the air gap. To ensure the operational reliability of the highway, it is necessary to minimize the number of pipeline connections. In addition, it is necessary to provide thermal insulation of the highway. For this, special insulation, cardboard, minvat, etc. can be used. This will prevent the formation of condensate on the surface of polypropylene pipes. To maintain the system, it is necessary to provide easy access to the closing fittings. To do this, in the places of its installation, the hatches are mounted, which in a wide range are presented in plumbing stores.

The first stage of work on the laying of pipelines involves the markup of the highway, which can be applied with a marker or pencil. Further operations are made in the following sequence:

According to the markup of the grinder or the perforator, the parallel deepening is performed. When working, the grinder recommends the use of disks for processing stone or disks with diamond spraying.

The gap between the strokes is removed using a perforator or chisel so that there is a wide recess.

A pipeline is placed in the prepared deepening, which is close to the cement-based solution.

Installation site is discharged with decorative material.

After completing the laying of pipes in an hour, the highway is tested. To do this, it is filled with water and are investigated for leakage. When performing hidden installation in the wall, the fastening of pipes is made using plastic fasteners. Metal fasteners can be used for large-diameter pipelines.

Good day, my reader or reader! In this article, I will briefly list the rules for the installation of polypropylene pipelines. The main operation, when installing polypropylene pipelines - soldering. From her and let's start!

Rules soldering polypropylene pipes.

Polypropylene tubes and fittings are connected to each other using soldering. The method is simple, but nevertheless some rules must be observed. Let us list these rules below:

• The first thing to do is to prepare the welding machine to work - mount the necessary nozzles on the heating surface, install the welding machine to the tripod (the device must stand on a flat surface), to include on the network and set the necessary temperature on the thermostat (there is nothing on cheap Chinese devices It is necessary - they are heated to 260 ° C automatically).
• After the "welder" warms up to the operating temperature, you can start a soldering. Before soldering, it is necessary to smoothly cut off the pipe, remove burgers from her edges and mark the distance to which the pipe will be inserted into the socket. Manufacturers are still recommended to degrease the surface of the pipes, but it is enough to make the pipe just clean. For reinforced metal foil pipes, it is necessary to use a special stripping (for pipes with an outer reinforcement) or a carrier (for pipes with internal reinforcement). If the pipe is reinforced with fiberglass, then you just need to cut off exactly.
• Next, the fitting and the pipe are inserted into the nozzle on the welding machine (it is important to insert the pipe and the fitting exactly, otherwise the soldering will be low-quality) and you start counting the time required for heating. For different pipe diameters, the time will be different (we will give it below in the table).

Diameter, mm.	The distance to insert the pipe into the socket, mm.	Heating time, sec.	Cooling time soldering, min
20	17	6	2
25	19	7	2
32	22	8	4
40	24	12	4
50	27	18	4
63	30	24	6
75	32	30	6
90	35	40	8

• After completing the work, you need to turn off the welding machine from the network and wait until it cools. After that, you can twist the nozzles and fold it into the box. Do not cool the welding machine with water. This will lead to equipment breakdown.

For greater clarity, everything that is said above Look this video:

For the installation of polypropylene pipes at the walls and in hard-to-reach places you will need a partner. There are difficult cases when you have to use two partners and two soldering blinds at the same time. Therefore, in advance, look for yourself a companion for installation work.

How to calculate the number of fasteners for polypropylene?

Support for polypropylene pipes.

Polypropylene pipes have regulations by the number of fasteners per unit length. This amount depends on the diameter of the pipe and the temperature mode. For clarity, let's give these data in the form of a table:

Pipe diameter, mm	Distance between fastener, mm.
	20 ° C.	30 ° C.	40 ° C.	50 ° C.	60 ° C.	70 ° C.	80 ° C.
20	600	600	600	600	550	500	500
25	750	750	700	700	650	600	550
32	900	900	900	800	750	700	650
40	1000	1000	900	900	850	800	750
50	1200	1200	1100	1100	1000	950	900
63	1400	1400	1300	1300	1150	1150	1000
75	1500	1500	1400	1400	1250	1150	1100
90	1800	1600	1500	1500	1400	1250	1200

Now you just need to split the overall pipe of the pipe for a distance indicated in the table and you will receive the number of fixtures. The location of the fasteners should be thought out separately. Usually, this is done in the process of creating a project. It is not necessary to save on the supports, they are needed to protect pipelines from deformations occurring under the action of temperature.

Tool for mounting polypropylene pipes.

For the installation of polypropylene pipes, the following tool is required:

• Welding machine.
• Nozzles - boopresses or pairs, depending on what your welding machine you have.
• Cutter for plastic pipes.
• The marker for applying the stamps to the pipe.
• Building level.
• Spanner to twist threaded connections.
• Belt key for combined couplings - a very convenient thing to twist the combined couplings without a hexagon.
• Thread, fume or anaerobic sealant for compaction of threaded connections

Key for combined couplings.

Not too long list turned out, but here the most needed and better not forget anything. In my own experience I know that it is extremely uncomfortable to work without a belt key and a marker.

The results of the article.

Installation of polypropylene The process is quite simple and not requiring long training. The first time you can spoil several fittings and meters of pipe, but this is a small price for knowledge and experience and should be paid. Moreover, the price of material is more than a democratic, compared to copper or metal-plastic. On this all, write questions in the comments and press the buttons of social networks!

The appearance of polypropylene pipes in the Russian market turned out to be very timely, when in most houses built during Soviet power, metal water pipes and heating pipes began to be unusable, because they fully served their time.

A period of some distrust of new plastic pipes lasted long. Consumers appreciated the quality, aesthetics and operational advantages of polypropylene pipes.

Today, it is already confidently stating that the test of polypropylene pipes time passed extremely successfully, and they became a more winning alternative to pipes from other materials. What requirements are the regulatory documents for these products, and how is it right?

Overview of government standards for polypropylene pipes

Most of the products all over the world apply various control systems governing their production and application.

The main regulatory documents in Russia are SP, SNIP, GOST: polypropylene pipes fall under the requirements of the SP 40-101-96, SNiP 2.04.01-85, GOST R 52134-2003 and others.

Basic requirements of GOST, placed on polypropylene pipes

GOST R 52134-2003 "Pipes pods from thermoplastics ... General specifications" regulates:

• Scope: Pipes from the thermoplastics of the circular cross section and are used to transport drinking and technical water, are intended for the arrangement of the systems of the WHO and DHW, the heating of residential and non-residential buildings.
• The main parameters and dimensions are given in the document in a tabular form, in this paragraph contains data on which, according to GOST 52134 2003, polypropylene pipe should have external and internal diameters, wall thickness, permissible deviations, and the like.
• Technical Requirements: Large paragraph contains characteristics, requirements for reliability, raw materials, materials, components, recommendations for completeness, packaging.
• Safety and Environmental Protection Requirements: This section indicates hazard classes in the production of pipes, contains reference requirements.
• Acceptance rules: It is described here about the methods of testing, sizes of parties, the order of sampling of pipes and fittings for test checks, etc.
• Control methods: Section regulates the procedure for testing products.

Large and important sections are also: transportation, storage conditions, installation of pipes. In addition, various calculated tables are attached to the GOST.

What regulates the joint venture

Rules, construction standards and rules establish regulations for design, installation and operation, and systems, including polypropylene pipes. Mounted taking into account the requirements of the joint venture and SNIP polypropylene tubes will work most effectively and long.

How to choose polypropylene pipes?

There are no prohibitions on an independent house in your house, therefore, in principle, a person who owns the installation skills and having an idea of \u200b\u200bthe design of sanitary systems, you can buy pipes yourself and accessories and carry out gasket.

Specialists in installing pipeline systems themselves acquire the necessary components and provide a comprehensive guarantee for the work performed (materials + installation).

To not be mistaken and purchase pipes with the desired characteristics, it is necessary:

1. carefully examine the certificate for polypropylene pipes in the store, it must contain information about the class of operation of the product according to Gosstandart, there are 6 classes of PP pipes:

1. estimate the quality of the execution of pipes and fittings: the outer and inner surfaces of the pipes must be smooth, the cross section should have a perfectly round shape; Presence is not allowed in the material of shells, cracks, burrs and bubbles; Color models must have a uniform color;
2. inquire about product guarantees, any pipe and components to it must be endowed with the provider's warranty.

It is important to take into account that the permissible storage temperature of polypropylene pipes is not lower than - 20 0 C. Therefore, it is not worth buying products in winter on the street or in unheated stores.

Polypropylene tubes are easy to install, reliable, aesthetic. They declared a long service life - 50 years. But it is necessary to remember that the long-term trouble-free use of pipeline systems mounted in compliance with standards is possible only under normal conditions.
