Dear all,
good day, i am working now in a subsea project our requirement were gate valves 2 & 4" gate valves with pressure class rating 10000 psi as per ISO 10423. Our vender proposed valves as per API 6A with expectations on pressure rating which is 7500ps. THE API 6A is not stated in API 6A , there are 10000 & 5000 psi.
My question is , is the different pressure rating influence the design variables: or the temperature ,the material selection and the stress limit calculations for materials are obtained independently from the design pressure (e.g .:fora 5k psi or a 10k psi the temperature
rating ,the material selection and the allowable stresses does not change ,as the related
formulas to calculate them ).
this task is quit urgent please
