NOTES: 1) 60 ksi design bolt stress is used for calculation. 2) Assuming new, non-coated and well lubricated bolts are used at room temperature; nut factor K=0.18. 3) Assuming maximum internal pressure follows ASME B16.5 Pressure-Temperature rating tables. 4) Assuming ASME PCC-1 bolting pattern is followed. 5) Flange imperfections, rotation, and deflection are ignored. 6) Assuming flange meets ASME B16.5 or B16.47 requirements. 7) Bolt torque values in above table are for reference only. User is responsible for applying appropriate bolt loads to properly seat the gasket. v3.0
