Could someone with some experience in stress relieving carbon steel process piping give me some insight on the B31.3 code requirements for this process? Our customer's PID declares a number of pipe weldments to be stress relieved, but that's the only information they give. They have not specified any particular temperature, hold times, or processing requirements. All of the piping is to be done to B31.3.
In the mean time...I'll have my nose in the code. If I'm not back in 15 minutes, please notify my next of kin...
