What are the characteristics of PP-R pipe?
PP-R pipe in addition to the general plastic tube light weight, corrosion resistance, no scaling, long life and other characteristics, but also has the following main features:
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, can also be used for pure drinking water system.
2, thermal insulation. PP-R tube thermal conductivity of 0.21w / mk, only 1/200 of the steel.
3, better heat resistance. PP-R tube Vicat softening point 131.5 ℃. The maximum operating temperature of up to 95 ℃, to meet the building water supply and drainage regulations 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, easy installation, 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 after recycling for pipe, pipe production. The amount of recycled material does not exceed 10% of the total, does not affect product quality.
