Novel steel wire mesh framework plastic composite pipe

Abstract

A novel steel wire mesh framework plastic composite pipe is a whole pipe formed by interconnection of a plurality of segments of composite pipe components sequentially through electric heat fusion joints in a welding manner, each segment of composite pipe component is formed by mutual wrapping of two or more layers of plastic pipes made of high density polyethylene, a steel wire mesh framework is arranged between two adjacent layers of plastic pipes, and the steel wire mesh frameworks and the plastic pipes are spliced into a whole through bonding layers. The electric heat fusion connection manner is adopted, the connecting strength and the sealing effect are obvious, and axial-tension-resisting capability of pipes obtained after connection is high. The novel steel wire mesh framework plastic composite pipe is formed by compositing two materials of steel and plastic, the phenomenon that plastic pipes difficultly overcome rapid stress cracking is avoided, and strength, rigidity and impact resistance superior to those of a common pure plastic pipe are achieved; the beneficial effect that the plastic pipes are small in weight is achieved, and mounting is convenient; double-face anti-corrosion performance the same with that of the plastic pipes is achieved, and the heat conductivity coefficient is low; the service life of the pipes is prolonged; and through adjustment of diameters of steel wires, thickness of plastic layers and the like, the pipes with different pressure grades are manufactured.

Description

technical field [0001] The invention belongs to the technical field of pipes, and in particular relates to a novel steel mesh skeleton plastic composite pipe. Background technique [0002] Pipes are mainly used to transport domestic water, gas, industrial fluids and other media. Currently, common pipes include steel pipes and plastic pipes. Among them, steel pipes are heavy, inconvenient to install, and poor in corrosion resistance; plastic pipes are easy to crack, lack strength and rigidity, and are resistant to corrosion. Poor impact. Due to the shortcomings of steel pipes and plastic pipes, the overall life of the pipes is short. For this reason, the applicant has designed a steel wire skeleton plastic composite pipe. When using it, it is necessary to connect several sections of composite pipes to form a pipe of the required length. , the traditional connection method is welding, but the welding method has poor axial tensile resistance.
