PCC-1 Appendix O – Flange Assembly Rules
COMPRESS provides the ability to assess bolted joints per ASME PCC-1 Appendix O. This procedure provides guidance on determining the appropriate assembly bolt torque\stress with due consideration for joint integrity.
Two approaches are available, the simple approach and the joint approach.
With the simple approach, an appropriate bolt stress is determined based on the target gasket stress. This is then converted to a target bolt torque.
With the joint approach, the following conditions are considered before arriving at a target bolt torque:
