Classification of hoses
According to the purpose, it is mainly divided into: threading hose, drainage hose, ventilation hose, shower hose, wiring harness tube.
According to the material, it is mainly divided into: stainless steel hose, metal hose, corrugated hose, rubber hose, plastic hose. Metal hose mainly refers to one is a spiral corrugated pipe; the other is an annular corrugated pipe. The spiral corrugated pipe is a tubular shell with corrugations arranged in a spiral shape. There is a helix angle between two adjacent corrugations, and all the corrugations can be connected by a helical line.
The annular bellows is a tubular shell with closed annular corrugations, and the waves are formed by series of annular corrugations. The annular corrugated pipe is formed from seamless pipe or welded pipe. Restricted by the processing method, the length of the single tube is usually shorter than that of the spiral corrugated tube. The advantages of annular bellows are good elasticity and low stiffness. Double hook hose, strong tension (>120 Kg), strong torque, to ensure no cracking, no water leakage.
