Piping made of steel mesh reinforced plastic composite pipe and method for making the pipe

摘要

This invention provides a method for manufacturing steel mesh reinforced plastic composite pipe, which includes: the transverse steel wires (11) are supplied to the steel mesh welding machine from the transverse wire reels hung outside the device, a fuzzy resistance welding technique is adopted to form the steel mesh framework by welding the transverse steel wires onto the longitudinal steel wires (1) coming from the longitudinal wire feeder. The formed steel mesh framework is continuously hauled off and passes through the combining die (9), the combining die embraces the steel mesh framework and receives the molted thermoplastic supplied from the side face of the combining die, the plastic and the steel mesh framework combine inside the combining die to form the semi-finished pipe, which is hauled off (7) through the cooling tank (6) to form the finished composite pipe. This invention also relates to a production line for manufacturing the composite pipe as well as a piping system formed by connecting the pipes with joining structures.
