24/4/2016 · 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.
