ASME PCC-1 Appendix O Joint Assembly

Proper flanged joint assemblies depend on the interaction of the flanges, gasket, and bolts.  ASME PCC-1 Appendix O investigates the interaction of flange stresses, gasket stresses, and bolt stresses to determine proper bolt torque values.

Why use Metalmark Engineering for your ASME PCC-1 Appendix O assessment?

Maximum Permissible Bolt Stress for the Flange, Sfmax calculation.

Metalmark Engineering uses a complete Appendix 2 flange assessment with WRC 538 to determine the Maximum Permissible Bolt Stress for the Flange needed for ASME PCC-1 Appendix O.

Assembly Bolt Stress, SBsel determination.

Metalmark Engineering determines the Assembly Bolt Stress and assesses if the upper bolt limit controls, if the lower bolt limit controls, or if the flange limit controls before determining if gasket seating stress is achieved.

Target Assembly Gasket Stress, Sgt determination.

Metalmark Engineering works with gasket manufacturers and does not rely on assumed default values for Target Assembly Gasket Stress, Maximum Permissible Gasket Stress, Maximum Operating Gasket Stress, and Maximum Seating Gasket Stress.
