Anyone could clarify to me if the NACE Requirement forbids the use of Socket Welded components or not. Thanks in advance for your help

RE: NACE MR 0175 and Socket Welding
It can be difficult to achieve the required hardness values and I'm aware of one project where there were significant in service problems that resulted from the SW on SW flanges (small bore).
I would specify that a minimum 2 pass hardness qualified weld procedure be used. In addition, some people specify that the welders must be specifically qualified for fillet welds - that qualification completed on groove welds is not acceptable as qualification for fillet welds.
