Corrugated pipe, also known as wave pipe, can be extruded with three materials of PE, PP and PA. Corrugated loom tubing can be used to protect wires and cables from mechanical damage such as cuts and splits. It has good flexibility, strong bendability, acid resistance, and resistance to The advantages of grinding, etc., play a role in protecting wiring harnesses, wires, cables, and are more suitable for protection of some corners or bent wires. It can be customized as flame-retardant type and split type according to customer requirements. Corrugated electrical wire conduit is widely used in industries such as mechanical equipment, automation control, automobiles, subways, and electrical switch cabinets.

A：It is recommended to use PA (polyamide) bellows in the following cases

In an environment without sulfuric acid, formic acid, acetic acid, nitric acid, hydrochloric acid, calcium chloride, methanol and strong oxidants; soluble in ethylene glycol, glacial acetic acid, chloroethanol, propylene glycol, 1,5-pentanediol, trichloroethylene at high temperatures , Methanol solution of zinc chloride, phenol, cresol and other solvents. Mainly used in the environment with a temperature range of -34～150℃; used in the sheath of the wire harness of automobiles, motorcycles and other motor vehicles; also used in the sheath of the wire harness of household appliances, precision machine tools and other equipment; Animal and vegetable oils and mineral oils have good stability; can withstand various concentrations of alkali.

B：It is recommended to usePP (polypropylene) bellows in the following situations

In an environment without strong acids and high concentrations of oxidants; soluble in aromatic hydrocarbons such as benzene, toluene and chlorinated hydrocarbons in an environment of≥80°C; stable to most oils, absorbing a small amount of mineral oil and vegetable oil. It is mainly used in the environment with a temperature range of -20～120℃; it is used for sheathing of wire harnesses of automobiles, motorcycles and other motor vehicles; it can also be used for sheathing of wire harnesses of household appliances, precision machine tools and other equipment.

C：The following cases recommended PE (polyethylene) Bellows

There is no oxidizing acid, no animal, vegetable oil, mineral oil in the environment; no aliphatic hydrocarbons, aromatic hydrocarbons, ketones, esters and other organic solvents in the environment. Mainly used in a temperature range environment of -40 ~ 80℃; suitable sheath for automobiles, motorcycles and other vehicles of the wire harness; can be used for household appliances sheath wire harness apparatus, precision machine tools and the like.
