What are the characteristics of valve pipes of different materials

Plastic PVC valve pipe material classification description:
PVC pipe has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes, and it has excellent corrosion resistance. The price is the cheapest among all kinds of plastic pipes, but it is more brittle at low temperature. The connection method is bonding and socket. Rubber ring connection and flange thread connection are mainly used for water supply and drainage, irrigation, gas supply, exhaust pipes, wire conduits, rainwater pipes, industrial anti-corrosion pipes, etc. in residence, industry and mining, and agriculture.
PP pipe features good corrosion resistance, good strength, high surface hardness, surface finish, and certain high temperature resistance. Connection method hot melt welding, flange thread connection is mainly used for chemical sewage, sea water, oil and irrigation The pipes are used for indoor concrete floors as heating pipes for heating systems.

CPVC pipe features excellent heat resistance, heat distortion temperature of 100 ℃, excellent chemical resistance, bonding method, flange thread connection is mainly used for hot water pipes.
PE pipe features light weight, good resistance, good low temperature resistance, non-toxic, relatively cheap, high impact strength, but low compression and tensile strength. Connection method: hot melt welding, flange thread connection is mainly used for drinking water Pipes, rainwater pipes, gas pipes, industrial corrosion-resistant pipes.
ABS pipe features excellent corrosion resistance, light weight, higher heat resistance than PE and PVC, but the price is more expensive. Connection method: Bonding and flange thread connection are mainly used for sanitary ware drain pipes, beggar pipes, sewage pipes, underground cable pipes, high-corrosion industrial pipelines, etc.
The strength of PB pipe is between PE and PP, and the flexibility is between LDPE (LDPE: low-density polyethylene) and HDPE (HDPE: high-density polyethylene). Its outstanding feature is its creep resistance (cold deformation). Winding and continuous, temperature resistance, and excellent chemical function. Connection method. Hot melt welding and flange thread connection are mainly used for water supply pipes, cold and hot water pipes, gas pipes, and underground high pipelines. GRP pipes have excellent corrosion resistance and light weight. , High strength, good portability and good function. Connection method: Socket apron connection and flange connection are widely used in petrochemical pipelines and large-diameter water supply and drainage pipelines.
