Can a hydrostatic test be carried out by inflating and applying pressure?
Thread Content
When performing a hydrostatic test on a plate heat exchanger, can compressed air be used to apply pressure right after filling it with water? The air compressor has a pressure of around 6-7 kilograms.
This is risky, right? However, it seems there is a standard (pipeline or container) that requires testing for water pressure, air pressure, airtightness, as well as testing with both water and air.
This is equivalent to a gas-liquid mixture, and safety considerations need to be taken into account.
It was explained quite clearly though~ The test pressures were also provided
It seems that for gas-liquid combined tests, verification calculations should be carried out or the necessity should be explained. It can’t be messed around with casually.
1. Usually, pressure is continued to be applied using a pressure pump. 2. During the commissioning pressure testing of the unit, since the tower is quite large, we used a combination of water and nitrogen in the past.
Inflation and pressurization are equivalent to a gas-liquid mixed pressure test, which is the same as a pneumatic pressure test
No. If it is to be used, it requires approval from the designer.
To be clear: it’s not possible. The pressure used in hydraulic testing is different from that in gas-liquid mixed testing; how can they be compared? Moreover, the requirements for gas-liquid mixed testing are also not the same as those for hydraulic testing. Am I clear?
