Flanges Max Allowable Pressure
Flanges Max Allowable Pressure
(OP)
My customer has specified some coils for an heat exchanger to be designed at 153.1 barg & 100°C with flanges 900#.
I already bought the flanges and I then realized that for 900# at 100°C the max allowable pressure is well below 153.1 barg, i.e. approx 139 barg!
I checked the worst operating conditions at one of the nozzles, which are 57°C & 147 barg, which are acceptable for 900# flanges.
My question is: can I keep the flanges?

Another solution is to perform a calculation of your flanges for 153barg@100°C. If they are adequate dimensioned you are allowed to use them for the specified pressure.
