valve casting radiography

valve casting radiography

valve casting radiography

(OP)
Does anyone have a good document on QA/QC for valve casting radiography?  I'm trying to write one for my company and it is difficult decyphering the various standards.  THANKS

RE: valve casting radiography

I'd suggest ASME B16.34 as a good place to start.  Annex Bn lists radiographic acceptance standards, and refers to some ASTM documents that may be helpful (E94, E142).  Figures 6-14 show typicla valve casting sections requiring radiography.

I hope this helps.

I suggest the following document from the Manufacturers Standardization Society.  SP-54 Quality Standard for Steel Castings for Valves, Flanges, and Fittings and Other Piping Components - Radiographic Examination Method
