PPR cold water pipe is formed by random copolymerization of polypropylene, PP-R is the late 80s, the use of gas phase copolymerization process to about 5% of the PP chain of molecules in the random polymerization (random copolymerization) and become a new generation of pipeline Materials, with its non-toxic, durable, easy installation and other characteristics, a wide range of application engineering, water conservancy, industrial and other aspects of the cold water pipe above.
PP-R cold water pipe characteristics
1, non-toxic, health. PP-R raw material molecules only carbon, hydrogen, no harmful toxic elements exist, not only for hot and cold water pipes, but also for pure drinking water system.
2, thermal insulation. PP-R tube thermal conductivity of 0.21w / mk, only 1/200 of steel.
3, better heat resistance. PP-R tube Vicat softening point 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 of 70 ℃, working pressure (P.N) 1.OMPa conditions, the service life of up to 50 years; at room temperature (20 ℃) service life of up to 100 years.
5, easy to install. PP-R has good welding performance, pipe, pipe fittings can be used hot melt and fused connection, the connection part of the strength is greater than the strength of the pipe itself.
6, materials can be recycled. PP-R waste after cleaning, broken recycling for the use of pipe, pipe production. The amount of recycled material does not exceed 10% of the total, does not affect product quality. |
