RE: PMI Testing on valves pipes and fittings
Is PMI testing recomended for trim materials of valves.The quality document ask for PMI testing for all presure containing ,pressure controlling and parts exposed to process fluids.
Doesnt this covers every thing.
Is in standard does it specifies what is pressure containing, pressure controlling parts.
Even for CS valves the trim material is SS.Does normally the PMI testing is done on this.
Does some one has extract from standard or sections from standard.I donot have a copy of API RP578 or EEMUA 149
How can I argue that PMI is not required for CS Valves.
Please clarify.
Thanks
Deepu
