Thanks for your response.... I would like to elaborate my query with example. A flanged joint, with spiral wound gasket, is subjected to an internal pressure of 1.5 MPa. 1) While designing for operating condition, if compressive stress in gasket is maintained at "m" times internal pressure (i.e...

My understanding of m & y factors of gasket: 1) "Factor m": In order to ensure leak proof flanged joint in operating condition, residual compressive stress in gasket shall be minimum "m" times internal pressure. 2) "Factor y" is interpreted as minimum gasket seating stress required to create an...

Thanks all for sharing opinion. I am also in agreement with what u said. But many designer simply follows MAWP whatever software shows. e. g. For specified design pressure of 400 psi, if calculated MAWP is 405.650 psi, same has been mentioned on nameplate. I strongly feel that it should be 405...

Good morning friends.... I have one query regarding no. of decimals in MAWP of vessel as below: “ In PV Elite, MAWP of vessel is specified till 3 decimals. Should we take any of the unit systems, commonly used in the world, none of the pressure gauge can measure pressure up to 3rd decimal. In...
