The steel mesh skeleton plastic composite pipe is a new type of improved steel skeleton plastic composite pipe. This kind of pipe is also called srtp pipe. This new type of pipeline uses high-strength superplasticized steel wire mesh framework and thermoplastic polyethylene as raw materials, steel wire winding mesh as the framework reinforcement of polyethylene plastic pipe, and high-density polyethylene (HDPE) as the matrix.
High performance HDPE modified bonding resin is used to closely connect the steel wire skeleton with the inner and outer layers of high density polyethylene, so that it has an excellent composite effect. Because the high-strength steel wire reinforcement is wrapped in the continuous thermoplastic, this composite pipe overcomes the respective shortcomings of steel pipe and plastic pipe, while maintaining the respective advantages of steel pipe and plastic pipe.
The steel mesh skeleton plastic composite pipe adopts high-quality materials and advanced production technology, which makes it have higher pressure resistance. At the same time, the composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas transmission pipeline systems. The fittings used for the polyethylene composite pipe with steel mesh framework are polyethylene electrofusion fittings. During the connection, the outer plastic layer of the pipe and the inner plastic layer of the pipe are fused by the inner heating element of the pipe, and the pipe and the pipe are reliably connected together.
The phenomenon of rapid stress cracking of plastic pipes is overcome. Since the structure of steel and plastic materials is composite, the rapid stress that is difficult to overcome by plastic pipes will not occur. It has strength, rigidity and impact resistance higher than ordinary pure plastic pipe, and is similar to low linear expansion coefficient and creep resistance of steel pipe. Light weight, easy installation, electric fusion joint is used for pipe connection, with strong axial tensile resistance, mature and reliable connection technology, and pipe fitting varieties and specifications.
