The structure of steel wire wound pipe is characterized by two or more layers of wire mesh reinforced layer between inner and outer pipe walls. The steel wire is used as high strength steel wire for reinforcement. The outer layer of the steel wire before winding is coated with a coating with hot melt bonding property and water resistance. After winding on the core pipe, the composite pipe with excellent performance can be obtained by heating, extrusion coating of the intermediate bonding layer and extrusion coating of the outer PE layer to ensure the hot melt bonding between the high strength steel wire and the inner PE layer.

High density polyethylene (HDPE) is used to reinforce the outer wall of UHMWPE reinforced by steel wire skeleton, and UHMWPE is used to reinforce the inner wall and the outer wall of UHMWPE. A reinforced metal wire structure layer is arranged between the inner wall and the outer wall of UHMWPE reinforced by steel wire. The macromolecule bonding layer between the inner wall and the outer wall of UHMWPE reinforced UHMWPE is This not only makes the reinforced wire seamless and effective protection, but also makes the reinforced structure layer and the inner and outer pipe walls fully fuse without the appearance of crack interface, thus eliminating the corrosion or damage of the pipe caused by the pressure or corrosive medium in the pipe, and greatly improving the quality and reliability of the pipe material.
