Steel wire mesh skeleton plastic composite pipe is a new type of improved steel skeleton plastic composite pipe. This pipe is also known as srtp pipe. This new type of pipeline is made of high-strength plastic-coated steel wire mesh skeleton and thermoplastic polyethylene as raw materials, with steel wire winding net as the skeleton reinforcement of polyethylene plastic pipe, based on high-density polyethylene (HDPE) as the matrix, using high-performance HDPE modified bonding resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, giving it excellent composite effect. Because the high-strength steel wire reinforcement is enveloped in continuous thermoplastic plastic, this composite pipe overcomes the disadvantages of steel pipe and plastic pipe respectively, while retaining the advantages of steel pipe and plastic pipe respectively.
Steel wire mesh skeleton plastic composite pipe uses materials and advanced production technology to give it higher pressure resistance performance. At the same time, this composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas pipeline systems. The fittings used for the steel wire mesh skeleton polyethylene composite pipe are polyethylene electrofusion fittings. During connection, the outer plastic of the pipe is melted with the inner plastic of the fitting using the internal heating element of the fitting, ensuring a reliable connection between the pipe and the fitting.
1. Overcoming the phenomenon of rapid stress cracking of plastic pipes, because the structure of steel and plastic is composite, so there will be no rapid stress that plastic pipes cannot overcome.
2. It has strength, rigidity, impact resistance exceeding ordinary pure plastic pipes, and features such as low linear expansion coefficient and creep resistance similar to steel pipes;
3. Lightweight, easy to install, pipe connections use electrofusion joints, strong resistance to axial tensile, mature and reliable connection technology, complete variety of fittings, can be connected to various pipes, valves, and equipment;
4. Double-sided anti-corrosion, with the same anti-corrosion performance as plastic pipes, high temperature resistance and corrosion resistance, low thermal conductivity;
5. Excellent structure, the reinforcing skeleton of the pipe and the inner and outer layers of plastic are mutually inclusive to form a whole, without the worry of detachment of the inner and outer layers of plastic from the reinforcement;
6. Smooth inner wall, no scaling, 30% lower head loss of the pipeline than steel pipe;
7. The pipe is designed for a service life of 50 years;
8. Different pressure grades of pipes can be manufactured by adjusting the diameter of the steel wire, the thickness of the plastic layer, etc.;
