If the pressure vessel has already undergone a pneumatic test, a leak test may not be necessary. (That’s wrong.)
If the pressure vessel has already undergone a pneumatic test, a leak test may not be necessary. (Mistake)
Yes, a pressure test is a strength test, while a airtightness test is a test of sealing performance. For pressure vessels whose design requirements call for a pressure test, the airtightness test can be carried out simultaneously with the pressure test, and the test pressure should be the same as that of the pressure test. Generally, after a pressure test, it is not necessary to conduct a leak test
Wrong. The airtightness test is primarily used to check whether there are any leaks in the container. Pressure vessels with a medium toxicity level that is extremely hazardous or highly hazardous, or those for which even trace leaks are not permitted by design, must undergo a leak-tightness test.
No. A pressure test is used to check the strength of equipment, while a leak test determines whether there are any leaks; their purposes are different and they cannot replace each other.
The answer is wrong; air pressure is used to test pressure resistance, while airtightness testing is used to detect leaks
The statement in this question is correct. A pressure test is a strength test, while a leak test is a seal integrity test. Generally, after a pressure test, it is not necessary to conduct a leak test anymore.
If the pressure vessel has already undergone a pneumatic test, a leak test may not be necessary. (Mistake)
If the pressure vessel has already undergone a pneumatic test, a leak test may not be necessary. Wrong. The purposes are different; one is to test strength, while the other is to test the sealing performance of flanges and similar components.
Error. ――–Strictly speaking, pressure testing and airtightness testing serve different purposes.
