Dear experts, what standards should be followed for nickel alloy pipes and flanges? I earnestly request guidance from the experts

For example, I need to choose NS312 Hastelloy now; there are some standards available for the pipes, but I still can’t find any standards for the fittings and flanges.

Just follow the standard flange and fitting specifications – is there a problem with that? For example, standards such as ASME B16.5/B16.9/B16.11 only specify requirements regarding dimensions, not the materials to be used. If it is a copper-nickel alloy, it can be handled in accordance with EMMUA 145/146.

Thank you for the reply. Have you used the national standard version? Do we have to follow the American standards?
