Unable to answer your query in reference to BPVC, but in reference to piping, be aware that any increases in allowable stresses from recent publications is not meant to be used in the re-design of existing pipework. This definitely applies to pipework designed/built prior to 1970.

Does any know the main difference between current editions and 1965 ed for ASME BPVC code, Section I. What my concerns are the header wall thickness calculation for SA-106 material, including the formula, allowable stress, ligament eff., etc.

It appears that Sec II was created in 1992, and what I had got for the design stress of SA-106, which was attached to Sec VIII 1965 Ed main body, were significantly different with the pre-1999 Sec II.

Best Regards,

Samuel
