Dear friends
Can we consider the design pressure of the vessel as credit instead of the PRESSURE SAFETY VALVE.
is it applicable as pre ASME SECTION 8
Instead of considering the psv ,increasing the design pressure of the vessel
I know that this solution is not good choice and have big cost impact but I want to know that is it correct or not?
in the P&ID I see for heat exchanger vendor did not consider the psv for tube rupture and also thermal expansion .
When we ask them they said that we increase the design pressure and in this case no need to consider the psv
Thanks
