Discussion on Opening Reinforcement for External Pressure Vessels
Thread Content
Assume a jacketed device with low pressure inside the cylinder; the wall thickness is primarily determined by the external pressure of the jacket. The cylinder has two nozzles, one located within the jacket area and the other outside it. When calculating the reinforcement for these openings, will you use the same calculated thickness for the cylinder section in both cases? When using SW6 for calculations, the thickness is determined uniformly based on the pressure applied to the inside of the jacket. Do you think this method of calculation is reasonable?
My understanding is that for nozzles outside the jacket range, in the absence of external pressure, it is reasonable to use the thickness calculated for internal pressure when determining the reinforcement required for the openings. I’m not sure if my understanding is correct

More or less, one is inside the jacket and the other is outside the jacket
