Hi, We are delivering stainless steel equipment to ships. When we are delivering equipment like this and without coating, I always spesify material of 316L grade or 304L because of the marine conditions.

Thanks metengr,
then it should be ok using ambient working pressure even at low temperatures as long as it's a group 2 or 3 material without further calculations.
I assume that the fact that some of these materials in group 2 or 3 are becoming weaker in a cold state, still allows ambient...
Hello metengr,
Sorry, I didn't explain the problem well enough.
The problem occurs when the temperature is outside of ASME B16.34; which lowest temerature is -29C.
I work with valves for LNG, LEG and LPG which have temperatures -163C, -101C and -46C, thus I need working pressure according to...
Hi,
I am currently calculating the shell test pressure for valve bodies in various materials and temperatures.
This is done in order to find the weakest state of the valve body, and from that state determine ambient test pressure.
This is no problem as long as I can find Temperature/pressure...
