Design of flanges using VIII Div. 2 for Reactor with T>800¬F
Design of flanges using VIII Div. 2 for Reactor with T>800¬F
(OP)
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 Section VIII Div. 1. I am trying to find a paragraph in the Code allowing to use Section VIII Div. 1 vealues (like for external pressure), i have checked Interpretations and Code Cases as well and found nothing.
Any idea to help me?
Regards,
Decode.
