Does any one know if there is a mill tolerance for the roundness of pipe, with the material being sa106 or sa53B and 30" OD x 30'-0" long with a .375" wall thickness?
Something this big we would normally roll, but with a spec of .010 roundness I though of pipe but can't find what the mill...
Thanks Steve,
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.
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...
