Learn MoreCalculate the minimum required wall thickness of a boiler tube that is strength welded to a header. The maximum allowable working pressure is 4450 kPa, and the mean wall temperature is 370oC. The tube material is SA-192 and the outside diameter is 50 mm.

Learn More24/4/2016 · Minimum Pipe wall thickness is almost always less than minimum PV wall thickness because the pipe diameter (nozzle diameter) is smaller than the vessel diameter. Once every wall thickness and diameter is chosen, then you MUST go back to each nozzle and determine if the "opening" in the PV wall requires "additional reinforcement" around the opening to maintain vessel strength.
