What is the procedure to correct misalignment of two courses in a vessel? Can the weld be cut open and redone, or does material on both sides of the circumferential weld need to be removed? The misalignment occurs where a 40 mm thick course butts to a 35 mm course. Where is this type of...
I have a 12 foot diameter penstock made of 3/8" thick plate. The penstock shell is exempted from PWHT since the plate thickness is less than 1.25" thick and carbon content is less than 0.3 per cent.
However, at the bifurcation where the pipe splits, a 2" thick stiffener (a T-shaped stiffener)...
Hello,
This is my first post and my question is trivial. I am trying to determine the minimum practical thickness that can be used for a 96" diameter pipe (longitudinal weld seam) with a very low pipe pressure(23 psig) and the fluid is just air.
B31.1 min thickness to meet the low pressure...
