Hello, does anyone have the GB 12337 2014 Steel Spherical Tanks from China but in english ?
Much appreciate the effort.

Gerg22, a question for you (just ou of curiosity) = what is the limiting maximum design pressure for such tanks ?

In other words is it comparable to API 620 ...or is it ASME VIII ?

Thanks

Considering the fact that spherical tanks are mostly used for LPG,ammonia or propane storage you can say that they are not quite storage vessels as more pressure vessels so i would use ASME VIII Div. 1 and not API 620 or API 650. I am actually more interested in detailed drawings, how to calculate their supports and how to determine the developed length of each piece of the shell. To calculate it's thickness i can use PVElite or bentley vessel.
