The steel skeleton plastic composite pipe is a composite structural pipe which is continuously produced in a production line by using a steel mesh which is wound and welded to form a reinforcing skeleton, a thermoplastic such as polyethylene as a base, and which are uniformly combined together.



Good creep resistance and long lasting mechanical strength

No rapid cracking will occur

Good impact resistance

Axial with appropriate flexibility

No fouling or waxing on the pipe wall

Non-toxic, non-decomposing, no microbial accumulation

Good temperature resistance

Smooth inner wall and low flow resistance

Easy to locate and track

The ring has sufficient stiffness

Small thermal expansion coefficient

Light weight

Good weather resistance and UV resistance

The inner surface is resistant to highly corrosive media, and the outer surface is adapted to the environment of strong corrosion.

Serialized tubing, fittings and connection structures form a complete and safe piping system

Standard sizes

Executive Standard: Steel skeleton polyethylene plastic composite pipe for oil and gas industry SY/T 6662.1-2012. (This standard also applies to polyethylene-plastic composite pipes for water supply and fire-fighting steel skeletons)

Physical and mechanical properties
