Which expert has conducted gas-liquid combined pressure tests, and how is the calculation done?
Thread Content
As the title suggests, it’s a 1,000 cubic meter spherical tank, and the client requires a gas-liquid combined pressure test. I’ve looked up many standards but am not sure how to carry out this test. I seek help from all the experts out there~
Just fill it with some water and then inflate it from above. It’s essentially the same as a pressure test, but load-bearing capacity also needs to be taken into account.
Thank you, but I don’t know how to prepare a strength calculation report here.
The strength calculation sheet is just based on the same formula used for pressure testing verification. The load-bearing capacity generally refers to the load carried by the supports as well as the local stresses. It should be included in these spherical tank standards.
It involves first filling it with some water and then inflating it, which is equivalent to a pressure test.
The design calculations and specific pressure test requirements are identical to those for pneumatic testing
Regarding the effect of that liquid that has been filled in, is it necessary to conduct a separate verification, or has the impact of the liquid already been taken into account during the pressure test? If a separate verification is required, how should it be handled?
The flushing part only affects the weight during testing.
