PP-R pipe advantages

PP-R (polypropylene random) pipe, also known as three polypropylene pipe and also known as random copolymer polypropylene pipe or PPR pipe, with energy-saving materials, environmental protection, light high strength, corrosion resistance, smooth wall is not scaling, construction and It is widely used in construction, municipal, industrial and agricultural fields such as water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and so on. PP-R pipe using random copolymer polypropylene extruded into a pipe, injection into a pipe.

   PP-R pipe in addition to the general plastic pipe light weight, corrosion resistance, non-scaling, long life and other characteristics, but also has the following main features:

1, non-toxic, health. PP-R raw material molecules only carbon and hydrogen elements, there is no harmful toxic elements exist, health and reliable, not only for hot and cold water pipes can also be used for pure drinking water system.

2, thermal insulation. PP-R pipe thermal conductivity of 0.21w / mk, only 1/200 of steel pipe. For hot water systems, generally no additional insulation material.

3, the better heat resistance. PP-R pipe Vicat softening point of 131.5 ℃. The maximum working temperature up to 95 ℃, to meet the building water supply and drainage specifications in the use of hot water system requirements.

4, long service life. PP-R pipe in the working temperature 70 ℃, working pressure (PN) 1.0MPa conditions, the service life of up to 50 years (provided that the pipe must be S3.2 and S2.5 series or more); room temperature (20 ℃) Life of up to 100 years.

5, easy installation, reliable connection. PP-R has a good welding performance, pipe, pipe fittings can be hot-melt and fused connections, easy installation, reliable joints, the strength of its connection is greater than the strength of the pipe itself. Hot melt connection will be the same kind of material pipe and pipe fittings connected into a perfect whole, to eliminate the hidden dangers of water leakage.

6, the material can be recycled. PP-R waste by the clean, broken recycling after the use of pipe, pipe production. Recycled material consumption does not exceed 10% of the total, does not affect product quality.

7, light weight

20 ℃ when the density of 0.90g / cm, the weight of only one-ninth of steel, copper tube one-tenth, light weight, greatly reducing the construction intensity.

8, corrosion resistance

Non-polar materials, the water of all ions and building chemicals are not chemical, not rust and corrosion.

9, pipe resistance is small

Smooth pipe wall makes the resistance along the metal pipe than the small, lower energy consumption.
