how to choose suitable corrugated pipe in different fields ?
there are many types of corrugated pipe, how to choose suitable type in different fields ?
i will introduce as followes:
A: PE (polyethylene) corrugated pipe is recommended in the following cases
In the environment without oxidizing acid, animal, vegetable and mineral oil; in the environment without organic solvents such as aliphatic hydrocarbons, aromatic hydrocarbons, ketones and esters.
It is mainly used in the temperature range of -40 ～ 80 ℃; it is used for the sheath of wire harnesses of automobiles, motorcycles and other motor vehicles; it can also be used for the sheath of wire harnesses of household appliances, precision machine tools and other equipment.
B: PP (polypropylene) corrugated pipe is recommended in the following cases
In environments without strong acids and high concentrations of oxidants; soluble in benzene, toluene and other aromatic and chlorinated hydrocarbons in an environment of ≥80 ° C; stable to most oils, and absorbs a small amount of mineral and vegetable oils.
It is mainly used in the temperature range of -20 ～ 120 ℃; it is used for the sheath of wire harnesses of automobiles, motorcycles and other motor vehicles; it can also be used for the sheath of wire harnesses of household appliances, precision machine tools and other equipment.
C. PA6 nylon corrugated pipe is recommended in the following cases
Free from sulfuric acid, formic acid, acetic acid, nitric acid, hydrochloric acid, calcium chloride, methanol and strong oxidants;
It is soluble in solvents such as ethylene glycol, glacial acetic acid, chloroethanol, propylene glycol, 1,5-pentanediol, trichloroethylene, zinc chloride in methanol, phenol and cresol.
It is mainly used in the temperature range of -34 ～ 150 ℃; it is used for the sheath of wire harnesses of automobiles, motorcycles and other motor vehicles; it can also be used for appliances such as household appliances, precision machine tools
The sheath of the wire harness; it has good stability to various animal, vegetable and mineral oils; it can withstand various concentrations of alkali. The appearance of the pe tube is difficult to see. The general method is to look at the color.
Luster, brightness, smoothness of the inner wall. The really reliable method is to test pressure. New material pipes can withstand 1.5 times the pressure
