Regarding the pressure testing fixture for heat exchangers
Thread Content
I’m wondering about the pressure testing fixtures for floating-head heat exchangers – how is the thickness of each component determined? Is it calculated using SW6 strength? We have always done it this way, but a tooling piece is used only a few times per year, and moreover a safety factor of 3 is applied when calculating the materials; so can the thickness of the pressure-testing tooling be reduced appropriately? What do people usually do? Thank you!
We also use strength calculations, but the thickness can be based on the effective thickness of the equipment flange; the tooling material can be Q235-A
It is also possible to consider adding reinforcement on top to reduce the thickness!
Even if it’s used just once, the thickness cannot be reduced casually~~~ This is a pressure vessel pressure testing procedure. Just include this cost in the quotation~~~~ It won’t save that much money^_^
I learned for the first time that we do indeed replace the fake flanges frequently as well.
