CPVC NBR Fittings(ABNT NBR 15884)

CPVC can withstand corrosive water at temperatures greater than PVC,contributing to its popularity as a material for water-piping systems in residential and commercial construction.

Material Properties

CPVC material and product characteristics

1

High   temperature resistance-Vicat softening point is 30-40℃ higher than that of PVC and can be used in   cold and hot water systems.

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
