I am working with an Indonesian local contractor and there is an unintelligent disputation here and now regarding Table PW11. They insist that the temperature mentioned in the top of the table, 455 Deg C, is the fluid service temperature even I had indicated there is no such water temperature...
Does any know the main difference between current editions and 1965 ed for ASME BPVC code, Section I. What my concenrs are the header thickness calculation for SA-106 material, including the formula, allowable stress, ligament eff., etc.
For a pressure seal valve with parallel slide gates, the pressure in the bonnet may increase during valve closed, and does anyone know how to determine the design pressure?
Does anyone know any background why ASME annuled code case N-480 on September 18, 2001? (except what said by "No longer needed"). Does the method and procedure mentioned in this code case had been replaced by others?

Does "...by using the external design pressure as an equivalent internal design pressure..." here means trE = (PE/P)*tr (as we always can calculate tr easily)? Where, trE - Required thickness based on external design pressure; PE - External design pressure; P - Internal design...
