Use ASME PCC-1 Appendix O to Fix Leaky Flanges

What is ASME PCC-1 Appendix O?

It’s all about fixing your leaky flanges by taking a deeper look at the flange assembly bolt stress and ensuring the gasket is sealing properly. ASME PCC-1 Appendix O has a lot of stress values to look up (or calculate) and using “defaults” isn’t going to help you solve real world problems. It is important to know where to get some of the stress values you will need in order to properly determine bolt torque values using ASME PCC-1 Appendix O.
