How to calculate the welded annular sealing flange of high-pressure heat exchanger
Thread Content
Dear teachers: How to calculate the welded ring seal of high pressure heat exchanger? See picture below:
The bolts have already been given a pretightening force to balance the axial force (some equipment also takes the gasket pretightening force into consideration), and the welding seal only plays a sealing role. It is equivalent to conventional forced sealing. It just seals and welds the outer edge of the gasket to completely eliminate leakage caused by the gasket itself.
Yours is equivalent to a metal flat gasket seal. There is no internal pressure on the outermost periphery of the gasket, so there is no need to calculate the seal weld.
Thank you so much； Then just use SW6 medium and high pressure vessel flat gasket seal calculation.
