Pipeline repair - wall thickness for new weld tie-in
(OP)
Hello, can anyone tell me guidelines/codes used when making a new weld into exisitng piping, specifically if there is corrosion or some other indication in the existing pipe, what are acceptable limits of the corrosion or indications where the new weld will be? Situation involves gas tranismission pipeline, tie-in for a new pup or spool piece, and inspection of the tie-in point where the new circumferential welds will be has shown corrosion. Thank you.

If you're in the US, I'd say ASME B31.8 for acceptable limits and API 1104 for welding.
