Step 1 : Calculate equivalent pressure
Step 4 : Calculation of bolt load for gasket seating condition Wm2
Step 3 : Calculation of total joint contact surface compression load Hp
Step 7 : Calculation of initial required tightening force in gasket Fb0
Step 5 : Calculation of actual gasket area Ag
Step 6 : Calculation of decreasing compression force in gasket (delta F)
Step 2 : Calculation of hydrostatic end force H
Step 8 : Calculation of total tightening force to seal joint W
Step 9 : Calculation of required bolt load T
