Welding of stainless steel pipes

Welding of stainless steel pipes

(OP)
Hi All
Have a question and sorry if it is irritant - is it mandatory to do 100% radiography test of welds for
stainless steel pipes (e.g. joint of two pipes or pipe and flange), and why?

Thank you

RE: Welding of stainless steel pipes

This should be defined in the standards or the tech specs.

RE: Welding of stainless steel pipes

Or the code of construction that you are fabricating the stainless pipes to.

The devil is in the details; she also wears prada.

RE: Welding of stainless steel pipes

The answer is no, it is unlikely that 100% radiography is mandatory. It is POSSIBLE that somebody has required this though, as a result of relying on 100% joint efficiency in a calculation, or because of the nature of the service.

RE: Welding of stainless steel pipes

In general it is not mandatory in most ASME Piping Codes but is for specific applications like severe cyclic service under ASME B31.3. I think in your case, as stated by moltenmetal, that your contract specification requires it.

RE: Welding of stainless steel pipes

Dear saraycad,

If it is in the client's spec, you need to carry it out. This is not as per any piping code.

I give you an example for better understanding. Suppose CS piping is upgraded to SS and the service is rich amine. Well, the client removes PWHT however retaining the RT.

Regards.
