This series of products is a new type of medium, high, and low pressure composite pipe made of high-strength superplastic steel wire as the reinforcement, and double-sided composite thermoplastic on the 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 pipe system are electric heating fusion fittings. When connecting, the inner heating element of the fittings is used to melt the outer plastic layer of the pipes and the inner plastic layer of the fittings, reliably connecting them together.
