UG-37 Exemption
UG-37 Exemption
(OP)
I have a vessel 36" OD 1200 MAWP w/ 1/8" Corrosion. The customer wants a 2" coupling, but with the corrosion it is not exempt from reinforcement. Is it possible to make the opening in the shell 2-1/8" and boss on the coupling to make it exempt. We would prefer not to use a repad.





RE: UG-37 Exemption
you can get any length and the I.D. of opening is around 2".
don't quote me on the id, but i think it's right

After posting I also realized a 2" coupling inserted may not meet UG-36 exemption. Apologies
