About water pressure testing and air pressure testing
Thread Content
I would like to ask you about the purpose of water pressure test and air pressure test? What time should be carried out?
Water pressure testing and air pressure testing are two methods, both of which can test the strength of pipeline equipment. Safety test, general water pressure test without special requirements. But to be honest, the water pressure of the equipment is still better, but * The water pressure on the line is so annoying. Once the water flows everywhere, it is difficult to find the leakage point. 2. The speed is slow, and many pipelines need to be welded and emptied at high points, otherwise the pressure cannot be pumped up, but new welding and evacuating will create new possible leak points.

The hydraulic pressure test is to test the strength of the pipeline, and the air pressure test is to test the air tightness of the pipeline. The order of testing is to first pass the hydraulic pressure test and then conduct the air pressure test.
I would like to ask, regarding the water pressure test, is it necessary to conduct a water pressure test every time the tank is opened and the test is completed? Thank you!
