PMA for ASME Carbon Steel Fittings and Flanges
PMA for ASME Carbon Steel Fittings and Flanges
(OP)
Dear all engineers,
Has anyone done the particular material appraisal, PMA, acc to PED, especially for ASME materials like A-105, A-106 grB A-234 WPB?
When we do the PMA for them, do I have to comply to content limitation for carbon, sulphur and phosphorus?
For example, the cast analysis for C% is about 0.3 max while the PED restricted it until max 0.23%. So can I say that I need to buy ASME materials like A-106 GrB with the C% at 0.23% as well?
Thanks!

One thing Ive seen suppliers do is that when an MTR mentions a material complies with PED 97/23/EC, a PMA is not required (most materials are often multiple certified, e.g. to A312 TP 316/L and 10216-5 1.4404/1.4401 - same goes for carbon steel).
