Background

The winding pipe is a pipe formed by winding and welding, and can be produced into a pipe with the diameter of three meters due to the unique forming process, which is difficult to be completed by other production processes. The winding pipe is a new product for replacing the traditional metal protection spring for protecting the rubber pipe. The winding pipe is corresponding to the traditional metal protection spring product, and has good wear resistance, ageing resistance and corrosion resistance; the outer surface of the hose can be more effectively protected from aging and abrasion. The winding pipe has more excellent convenient, environment-friendly and energy-saving effects relative to rubber pipe spring protection products and other sheath products. The winding pipe is mainly applied to the protection of wires and cables with wear resistance requirements of various engineering machinery, mining hydraulic equipment and the like. The protective material can completely cover the protected product to form the protective effect of effective abrasion and ultraviolet resistance so as to protect the rod-shaped objects;
