2

Compressive   strength-the wall thickness of the pipe under the same pressure can be   thinner than that of PVC.

3

Corrosion   resistance-enhances the corrosion of fluids such as acids, alkalis, salts,   oxidants, etc., and can be used in industries such as steel, metallurgy,   petroleum, chemical, fertilizer, dyes, pharmaceuticals, electric power,   environmental protection, and sewage treatment

4

Good   heat insulation performance-has extremely low thermal conductivity,   therefore, the pipe made of CPVC has light weight, good heat insulation   performance, and does not need heat preservation

5

High   flame retardant-can be used in fire piping system

Chemical component test

Annual Chemical Extraction

Hygiene

Residual  Vinyl Chloride Test

Hydrostatic Burst Test

At 23°C, 60-70s, the minimum burst strength   see Table 6, no burst .
