Gentlemen,
I am now designing a Reactor with Design Temp of 850F using Section VIII Div. 2. For the design of flanges i am facing problems because Table 3 of Section II-D limits the maximum Use Temperature of Bolts to 800F for all the materials. Same table provides temperatures upto 1500F for...
I have feced this question before, you need to check your flange using Appendix to for Div 1 vessels in particular if your design temperature for both conditions is different. B16.5 does not provide any rating for external pressure
