Piping pressure testing
Thread Content
What is the difference between a pipeline strength test and a leak tightness test? Are both tests necessary, or is it sufficient to pass just one of them?
Hydraulic pressure testing is a strength test, while airtightness testing is a leakage check
Both must be carried out: the hydrostatic test is done after the piping is welded, while the airtightness test is performed before commissioning.
The hydraulic test is used to assess strength, and it is necessary to carry out； The integrity test is related to factors such as the hazard level of the medium and its value; it should be carried out as necessary, depending on one’s specific circumstances.

Both hydrostatic pressure testing and airtightness testing are required, for different purposes.
