API 620 Manway Cover
API 620 Manway Cover
(OP)
Hi everyone,
I have a tank that has to be constructed to API 620 and don't have the API books because 99% of our work in ASME sectI & sect VIII. My question is how do you calculate the thickness an O.D. on a 22"(pipe size) manway cover that is 304 stainless steel and the tank is 17'-0 high and 8'-6" O.D.. Any help would be appricated
Thanks

With sect VIII I come up with 28"o.d. x .500 tk. 40-1/2" bolts. I just wanted to see if I can get away with a lighter (.375)thickness under API620. Appriciate the response.
