Discussion on opening reinforcement for oblong holes in atmospheric pressure vessels.
Thread Content
The design pressure is atmospheric pressure, the design temperature is room temperature, and the design is based on ASME. With an inner diameter of 1200 mm, it is a vertical vessel; there is an oblong hole in the middle of the cylinder, used as a sight glass, with a major axis of 450 mm and a minor axis of 150 mm. How to equivalently treat it as a circular hole for hole reinforcement.
Since the design pressure is at atmospheric pressure, it is equivalent to an open tank; structural reinforcement only needs to be considered.
