Questions regarding the leakage test for atmospheric pressure vessels
Thread Content
I have recently designed a stainless steel container at atmospheric pressure. Due to the nature of the medium contained within the container, I am considering conducting a leak test after filling it with water. The problem I’m facing is that the design pressure specified in the specifications is atmospheric pressure, with no specific numerical value given. So, if I decide to carry out a airtightness test, how should I determine the pressure value for that test?； Additionally, could I consider conducting a kerosene leakage test as a substitute for the airtightness test? I would appreciate some guidance from those with experience. Thank you
If it is a container, the operating pressure is at atmospheric pressure; the design pressure can be set at 0.1 MPa, and the airtightness test can be conducted at 0.1 MPa as well
If it is a container, the operating pressure is at atmospheric pressure; the design pressure can be set at 0.1 MPa, and the airtightness test can be conducted at 0.1 MPa as well
For large storage tanks, a gas-tightness test can be conducted on the tank top, with a pressure of not less than 0.35 KPa
The pressures exerted on various parts of commonly used containers during water leakage tests and airtightness tests are different, and these pressures must be calculated; otherwise, deformation may occur.
What is your design pressure? If it isn’t specified on the drawings, a leak test cannot be carried out
There seems to be a standard for this; check the standards for pressure vessel manufacturing. It appears that the design pressure for equipment operating at atmospheric pressure is generally 0.18 MPa
Which standard is it under?
It is not recommended to conduct a gas-tightness test; a hydrostatic test is usually sufficient~
