Kinds of polypropylene pipes

Before you give preference to a particular product, it is necessary to get acquainted with existing types of polypropylene pipes. The characteristics of the material used and a method of reinforcement largely determine the possible scope of a particular brand and lifetime of the mounted pipe.

In material manufacturing

For the manufacture of polypropylene water pipes used:

• PPH - polypropylene homopolymer. The base material which is first used for the manufacture of pipe materials;
• PPB - a block copolymer having increased strength;
• PPRC (PPR) - a random copolymer of propylene with ethylene;
• PPs - polypropylene special purposes.

Attention! Device for hot and cold water systems use elements made from polypropylene last three species.

For reinforcement mind

The method of reinforcement is dictated by the kind of material used. Manufacturers use chopped fiberglass or aluminum. Amplification using aluminum involves pasting foil 0.5 mm thick between two polypropylene layers. The position of the reinforcing layer is selected individually. It can be centered on the wall or close to the outer side. Technology reinforcement using glass fibers involves the preparation of raw materials consisting of resin and fibers, and subsequent punching through the extruder. The result is a solid product whose elements are all securely interconnected.

Polypropylene pipes for hot and cold water: the basic specifications

The main technical characteristics of the piping materials include polypropylene nominal pressure and a maximum operating temperature. Polypropylene tubes are usually divided into:

• PN10 with a maximum operating pressure of 1 MPa. They are used in the device system of cold water (20 ° C) or "warm floor" with the greatest heating to 45 ° C;
• PN16To withstand 1.6 MPa. When relevant device "warm floor", heated to 60 ° C;
• PN20Topical at the device the hot water system. They are able to withstand pressures up to 2 MPa at the maximum heating of the fluid to 80 ° C;
• reinforced productsUsed for the hot water system installation. Such polypropylene tubes at the operating temperature of 95 ° C and an operating pressure of 2.5 MPa retain their performance characteristics.

Attention! When selecting a suitable embodiment except Performance should pay attention to the size specified in the design documentation.

Technical requirements for polypropylene pipes for water supply according to GOST

In the manufacture of pipe materials are taken into account the requirements of regulatory documents. GOST for polypropylene pipes for water supply prescribes requirements not only to the process of production and assembly, but also storage and transportation.

«Before choosing a piping materials with specific transverse dimensions need to be concerned about the availability of the equipment by means of which the individual elements are connected. "

For pipelines having a length of less than 10 m, experts advise purchase product 20 mm in diameter. Greater than 20 m, the less 30-25 or 32 mm. If the length of hot or cold water supply system exceeds 30 m - 32 mm.

What better polypropylene pipes for water supply

There is a limit on the maximum temperature of makes you wonder what Polypropylene pipes for water supply better. We offer this deal, depending on the installation of a system to be implemented.

Polypropylene pipes for hot water

Piped water is heated to 85 ° C. By selecting polypropylene pipes for hot water to be preferred articles of PPRC (PPR) or PPs, having the necessary characteristics. PN20 installation can only be carried out together with reduction gear, the limiting pressure. PN25 is the optimum one for the hot water system. Such products can withstand hammering.
