After the compressed air pipeline has passed the strength test, is it still necessary to conduct a leakage test (air-tightness test)? ? It depends on the level of pressure; if the pressure is low, there’s no need to proceed, but it’s necessary to do so when the pressure is high
It depends on whether there are any fittings or instruments that have not undergone pressure testing If there is, it needs to be done.
Do it once for extra protection. . . . . . . . . . . . . . . . . .

However, strength tests cannot be conducted on the entire system as a whole; components such as equipment, instrument elements, and expansion joints need to be removed or isolated during strength testing. The airtightness test involves connecting the entire system together to check for leaks, and it is carried out at the pressure under which the pipelines operate normally. It represents the final inspection and verification before introducing any medium into the system. Generally, the requirements for water, gas, steam, and air pipelines in utility systems are relatively more relaxed.
I agree with the opinion from floor 9; it should be done.
According to the specification requirements, compressed air is not considered a medium for leak testing. It’s not necessary to do it.
