Pipe is an alternative to traditional metal hose to protect new products retaining spring. Pipe is generally made of nylon or polypropylene material, product-based electronic materials with PE (polyethylene). Pipe is mainly used in a variety of construction machinery and mining hydraulic equipment and wear-resistant wire and cable protection requirements. Because it can be completely covered by protection products, the formation of an effective protective effect of wear and UV resistant and protective role in many rod-shaped objects outside. Pipe correspond to traditional metal retaining spring product has good wear resistance, aging resistance, corrosion resistance can be strong; the outer surface is more powerful anti-aging and anti-friction hose protection, and improved aesthetic bent wire. Pipe spring relative to the hose care products and other products with superior jacket convenient and environmentally friendly energy-saving effect. Pipe is generally flat inner surface, an outer surface of the sub-plane and two arc. Usage: first with protection with a fixed starting point at one end, and then surround is not tight in a clockwise direction, then the wire bundle as a whole.
