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.
ASME PCC-1 Appendix O Required by PIP
Did you know that ASME PCC-1 Appendix O is required by Process Industry Practices (PIP)?
Yes, everyone knows that using ASME PCC-1 Appendix O reduces leaks and emissions.
Yes, everyone knows that using ASME PCC-1 Appendix O makes your facility safer.
Yes, everyone knows that using ASME PCC-1 Appendix O saves you money.
But not everyone knows that ASME PCC-1 Appendix O is required by PIP. Appendix O definitions like Target Assembly Gasket Stress, Sgt and Assembly Bolt Torque, Sb are being mentioned in courtroom arguments. It is a great time to start learning more about bolted flange joint assembly.
Please review PIP VESV1002 Part 4.4.3 Nozzles, Manways, and Flanges for more information regarding this PIP Specification for Vessels.
