Mr. MJCronin's thanks for such helpful references and comments about Category M fluid.
Basically it is a ammonia filling station that we are designing. Where temperature ranges from 5 to 50 C. But we are operating it at 20 C and 8 barg pressure(ammonia vapour Pressure). From your reference...
We are designing a piping system for anhydrous ammonia service basically ammonia filling station. we are using ammonia as non-refrigerated system.
From B31.3 i understand that I lie in Category M Fluid service.(Please correct me if I am wrong). So, for that I suggested to use low temperature CS...
Dear davefitz,
i just want to clear my concept that should the design parameters of vessel and piping be same or we can select different parameters.
vessel is designed at 33 bar and -40 C/+60C. i am asking for piping parameters.
vessel is designed at high parameters because at ambient...
As a fresh piping designer, i have to design piping for anhydrous ammonia. the design parameters for ammonia storage vessel are:
Design pressure: 33 bar
Design temperature: -40 C/60 C
but operating conditions are:
operating Pressure: 9 bar
Operating temperature: -33 C
So, for the piping...
