Russian Pressure Vessel Code(s) and Standards

I saw a translation of it 13 yrs ago. Not a very good translation- "variable pressure" was translated as " slippery parameters", for example.
They use different alloys, typically add vanadium to all alloys, and have unusual theories of metallurgical damage. Could be tricky specifying QC and fab procedures, since you need to be familiar with types of failures common to those alloys.

We designed many vessels/ exchangers for the Russian market and used ASME VIII-1 Code. You need a special Russian subcontractor to arrange for the acceptance. (Each item needs a so called "Pasport" which is a lot of paper work in Russian language)
Most Russian pressure vessels can be designed to ASME, providing they have a) Passport, b) Gost R certificate C)GTTN Permit all of which invole a paper chase and a cost. Pepole like SGS can advise cost's for the papper chase. The only point on design/materials would be impact requiments normally low temp and differ from the ASME standard.
Dear Donholte
I am familiar with russian nuclear pressure vessel design code (that is like ASME III) and like ASME, I think there is a little difference between nuclear and non nuclear codes (as you know difference between design procedure of ASME VIII Div 2 and ASME III is not so much).
the russian code on nuclear pressure component design is PNAE G 7-002-86 and it means that it is not updates since 1986 that is one of the most disadvantages of this standard.
According to this standard the safety factor is 2.6 on ultimate tensile strength and 2/3 on yield strength which of them is smaller.
