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
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
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
Product application range
Chemicals - Industrial piping and discharge pipes for the transport of corrosive media in acid and alkali salt manufacturing, petrochemical, fertilizer, pesticide, pharmaceutical and other industries.
Oilfields - oilfield gathering pipes, sewage pipes, crude oil, refined oil conveying pipes, oil well injection polymer pipes, brine processing pipes, etc. It is especially suitable for medium transportation of sulfur, oil, gas and water.
Municipal construction - urban water supply and drainage, natural gas and gas transportation.
Ships - life pipes and structural piping systems such as sewage pipes, water supply and drainage pipes, ballast water pipes, etc.
Mine - slurry conveying pipe, engineering well pipe, pumping pipe.
Agriculture - used in deep well pipes, filter pipes, irrigation pipes for drylands, culvert drains, etc.
Seawater transport – used for seawater transport in desalination plants, seaside power plants, and seaport cities.
