This series of products is a new type of medium, high, and low pressure composite pipe material with high-strength superplastic steel wire as the reinforcement and double-sided composite thermoplastic outer and inner layers. Because the reinforcement is encapsulated in continuous thermoplastic plastics, this type of composite pipe not only overcomes the respective shortcomings of steel pipes and plastic pipes, but also has the common advantages of steel pipes and plastic pipes. It is a solution to the urgent need for large-diameter rigid pipes in fields such as construction, municipal engineering, petroleum, chemical industry, pharmaceuticals, food, mining, gas, etc. The pipe fittings used in the steel wire mesh plastic reinforced composite pipeline system are electric heating melting pipes. When connecting, the inner heating element of the pipe fittings is used to melt the outer plastic layer of the pipe and the inner plastic layer of the pipe fittings, reliably linking them together.
