HDPE steel wire mesh skeleton composite pipe

Steel mesh skeleton plastic composite pipe adopts high-quality materials and advanced production technology, which gives it higher pressure resistance. At the same time, this composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas pipeline systems. The pipe fittings used for steel mesh skeleton polyethylene composite pipes are polyethylene electrofusion fittings. During connection, the heating element inside the fitting is used to melt the outer plastic of the pipe and the inner plastic of the fitting, reliably connecting the pipe and the fitting together.

Product Features

1. It overcomes the rapid stress cracking phenomenon of plastic pipes. Since the two materials of steel and plastic are composited, the rapid stress that is difficult to overcome with plastic pipes will not occur.

2. It has higher strength, rigidity and impact resistance than ordinary pure plastic pipes, and has characteristics similar to steel pipes such as low linear expansion coefficient and creep resistance;

3. Light weight, easy to install, the pipeline is connected with electrofusion joints, which has strong axial tensile resistance, the connection technology is mature and reliable, and the specifications and varieties of pipe fittings

are fully developed, and can be connected with various other pipelines and valve equipment;

4. Double-sided anti-corrosion, has the same anti-corrosion performance as plastic pipes, and has high service temperature and corrosion resistance, and low thermal conductivity;

5. Excellent structure, the reinforced skeleton of the pipe and the inner and outer layers of plastic are mutually integrated into a whole, without the worry of peeling between the inner and outer layers of plastic and the reinforcement;

6. Smooth inner wall, no scaling, and the head loss of this type of pipeline is 30% lower than that of steel pipes;

7. The overall service life of the pipe is designed for 50 years;

8. Pipes with different pressure ratings can be manufactured by adjusting the steel wire diameter, the thickness of the plastic layer and other parameters;

Application Scope

Steel mesh skeleton plastic composite pipe is a new type of pipe with excellent performance, which is widely used in oil fields, power plants, chemical and petrochemical enterprises, water supply companies, municipal gas, seawater utilization pipelines and other fields.
