Inspection issue
(OP)
Dear experts please suggest me solution for following issue
I am inspecting a vessel as per API 510. Vessel name plate shows that it was manufactured on british standard 5169 but its material identification is not available. In fact no other documents are available. Please tell me what i will have to do? Should i move to material testing or any other solution exist?

Check Manufacturer, local Jurisdiction for detailed information if (NBIC/PVD) checks are not available.

The other [more intelligent] choice is to assume that the vessel builder was competent. So start using common steels for your calc's and find one that works with the vessel's original thickness. A good inspector will search around with the UT meter and be able to determine what the original thickness was, unless everything on this vessel experienced a uniform corrosive attack [think 100% full of acid; not very likely]. Then, using the material strength that will 'work' with the original thicknesses, evaluate your vessel and see if it is OK or requires a derate and/or repairs.
