How to correctly test the pressure of the Automotive Wiring Harness Protection Sleeve?

With the progress of society, the rubber and plastic industry is also booming. The most prominent of these are automotive wiring harness protectors and latex tubing. Automotive Wiring Harness Protection Sleeve are mostly used in waterworks and mine drainage pipes in industry. Although Automotive Wiring Harness Protection Sleeve are widely used in various industries, people still have certain doubts about their pressure resistance. And I don't know how to correctly test the pressure of the Automotive Wiring Harness Protection Sleeve. The following editor will introduce it in detail for you.

In terms of industrial water supply pipes and drainage pipes, accidents are generally caused by the pressure not passing the test, so the pressure of the Automotive Wiring Harness Protection Sleeve must pass the test. Generally speaking, the pressure test of the Automotive Wiring Harness Protection Sleeve is mainly divided into low-voltage test and high-voltage test. When testing, we can use water as the test medium.
First of all, the test pressure is 1mPa during the low-pressure test, and the pressure is maintained for 5 minutes. If no liquid leakage is found in the pipe body, it is qualified. Secondly, the test pressure of the water supply pipe and drainage pipe is twice the working pressure, and the bursting pressure is generally 3-4 times the working pressure, and the pressure is maintained for 3 minutes, which is qualified. In short, the Automotive Wiring Harness Protection Sleeve used as a pipe must be able to withstand both low pressure and high pressure.
