Steel mesh skeleton plastic (polyethylene) composite pipe (hereinafter referred to as composite pipe) is a new type of composite pipe with independent intellectual property rights. This kind of composite pipe uses coated high-strength steel wire to wind and strengthen the existing pure PE pipe, so that the nominal pressure of the pipe can easily reach more than 5MPa (diameter ≤ φ 200), 2MPa (diameter ≤ φ 400), and the pipe wall thickness is lower than that of pure PE pipe.
The steel mesh skeleton plastic composite pipe is a new type of steel mesh 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.
Structural characteristics of steel mesh skeleton plastic (polyethylene) composite pipe The structural characteristics of steel mesh skeleton plastic (polyethylene) composite pipe are that there are two or more layers of steel mesh reinforcement layer formed by winding between the inner pipe wall and the outer pipe wall. The steel wire for reinforcement is high strength coated steel wire. Before winding, the outer layer of the steel wire is covered with a coating with hot-melt bonding property and water blocking effect.
