Calculation of the thickness of the method ring
Thread Content
Operating conditions for a square flange designed by the company: pressure of 0.02 MPa, temperature of 120°C. Material: Q235-B. Flange specifications: outer – length*width = 645*495, inner – length*width = 555*405, thickness 12mm. Gasket: EPDM, narrow-face sealing. Short section: 550*400, thickness 2mm. (Bridged section with a flange width of 25 mm). Bolt: 22-M12 (not necessarily required). The original thickness was an empirical value; now the company requires a calculation sheet. The thickness I obtained through standard calculations is too large. Who can help me with a finite element analysis or a better verification method? Thank you.
0.02 Mpa can be calculated directly as normal pressure
It is a pressure vessel at normal pressure, so no calculations are needed; a thickness of around ten to fifteen millimeters is sufficient.
