ASME VIII B&PV
ASME VIII B&PV
(OP)
My company is involved in a chemical sourcing project in China. Our client has called for ASME 8 (or equivalent) iso tanks to be used for transport.
In checking with the Chinese Certification Society (which is a member with IACS)I was unable to find any relevant equivalencies from CCS --> ASME 8 in terms of material.
Our concern is that the Chinese material will not be up to snuff in terms of ASME 8 standard.
If anyone has any information that they could share, I would appreciate it. The material in question is GB713 (Steel plates for B&PV) which we believe is carbon steel but that is not confirmed at this time.
Any ideas folks? Thanks in advance!

I found this link when I googled GB713:

One of the other forum posts on here said that you could re-certify foreign materials, however, that seems like it would be a costly endeavor. Any idea on the equivalency of ASME 8 to CCS?
RE: ASME VIII B&PV
Finding the nearest equivalency will only give you the starting point for re-certification. ASME Section VIII requires all materials to conform to one of the specifications in Section II. I don't think you'll find GB713 there.

Considering the lack of available carbon steel gas tanks available for lease, we had to commission one of them to get built. Ideally, ASME carries quite a bit of weight behind it as it is internationally accepted (from my personal experience anyway). We are trying to pair these two tanks as both ASME 8 instead of one ASME 8 + one CCS just to make the project uniform and also to avoid any last minute hitches.
I know the Chinese have recently renamed their standards (in 2007 I believe) so GB713 is now something like Q245R where the Q and the R stand for something. As you can tell, material isn't my strong suit so please bear with me.
I'm wondering if there is a conversion calculator/chart out there somewhere. Any ideas?

As to the choice of ASME VIII or ASME XII, that's entirely between you, your regulator, your victims, and their lawyers. But I will say that the ASME XII rules considered some accident scenarios that ASME VIII did not, and your design should account for those possibilities regardless of which code you use.
RE: ASME VIII B&PV
Obviously the professionals, who have the knowledge of these codes will be looking at this project with a fine toothed comb, but I'm glad I have a semi grasp on the concepts anyway.
Thanks again!!!
