What level of materials certification
What level of materials certification
(OP)
The "pressure equipment" requisitioning engineer would normally specify the required materials certification to the level 3.1B or C per ISO 10474, depending on the hazard level and other conditions. However, it seems that the structural engineers tend to be a lot more lenient towards the fabricators supplying, for example a piperack supporting a large Air Cooled Heat Exchanger. The Structural guys requirements slipped down to 2.1 or 2.2 as per ISO 10474. Is this normal practice or is there scope for improvement in our structural department practices?

Is the COC or CMTR acceptable certification coming from an obscure Chinese steel manufacturer or would you ask additional certification , backed by any reputed agency - say DNV, LLoyds, etc?
