On the issue of cross-sectional calculation after strengthening ring openings (creating gaps)
Thread Content
An internal reinforcement ring is provided on the plane of the pressure vessel saddle; since the medium is a gas containing water, semi-circular holes are made at the top and bottom of the reinforcement ring. After the opening is made, is the cross-section of the reinforcement ring calculated based on the specifications, or based on the minimum cross-sectional dimensions at the location of the opening?
The cross-section of the reinforcement ring after the opening should be calculated based on the minimum cross-sectional data at the location of the opening. This is done to ensure structural safety, as openings reduce the cross-sectional area of the material, thereby affecting its strength and stiffness. .
Take a close look at GB150; when the circumferential dimension meets the standard requirements. It can be calculated as a full circle. Generally, small holes have little impact.
