Description

Technical Field

[0001] The utility model relates to the technical field of skeleton composite pipes, in particular to a durable steel wire mesh skeleton polyethylene composite pipe. Background Art

[0002] Polyethylene steel wire mesh skeleton composite pipe is made by using high-strength steel wire to spirally wind left and right to form a steel mesh skeleton. The steel mesh skeleton is used to increase the hardness of the composite pipe. At present, polyethylene steel wire mesh skeleton composite pipe is widely used. It has the characteristics of smoothness, low resistance and light weight. However, the wear resistance of polyethylene material is not high. It is easily affected by fluid friction when used for a long time, which affects durability. Further improvements can be made.

[0003] After searching, it was found that the publication number is CN218914014U, and the name is a polyethylene steel wire mesh skeleton composite pipe. The application proposes that the existing polyethylene steel wire mesh skeleton composite pipe has poor resistance to longitudinal tensile strength. When the outside is impacted, the polyethylene steel wire mesh skeleton composite pipe will be deformed, resulting in poor sealing of the composite pipe, which leads to the problem of liquid leakage inside the polyethylene steel wire mesh skeleton composite pipe. By installing a leak-proof box, grooves, indicator lights, liquid level sensors and single-chip microcomputers, it is convenient to monitor the leakage of liquid inside the polyethylene steel wire mesh skeleton composite pipe and promptly notify the staff for maintenance. However, the leak-proof box, grooves, indicator lights, liquid level sensors and single-chip microcomputers used in the application have complex structures and high costs, and have exceeded the scope of pipelines. They are very troublesome to use and can be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
