A plastic coated steel pipe is a steel plastic composite steel pipe which is based on steel pipe and welded with a plastic anti-corrosion layer on the inner surface of steel pipe (bottom pipe) through spraying, rolling, soaking and suction processes or welded with plastic anti-corrosion layer on the inner and outer surfaces.

Plastic coated steel pipe has excellent corrosion resistance and relatively small friction resistance. Epoxy coated steel pipe is suitable for water supply and drainage, sea water, warm water, oil, gas and other media, PVC coated steel pipe is suitable for drainage, sea water, oil, gas and other media.

Plastic lined flanged steel pipes

Advantages of plastic coated pipe:

It is suitable for buried and humid environment and can withstand high temperature and extremely low temperature.

Strong anti-interference ability. If plastic coated steel pipe is used as cable sleeve, it can effectively shield external signal interference.

Good pressure strength, maximum pressure up to 6Mpa.

Good insulation performance, as the protective tube of wire, leakage will never occur.

There is no burr and the pipe wall is smooth. It is suitable to wear wires or cables during construction.
