The tubing was purchased and shipped from an approved vendor (Tube Sales). But, we failed to notice that the CMTR did not contain a statement that the tubing, manufactured by Sandvick Steel Co., was produced under their QSC program. Sandvick is a Quality System Certificate holder, but this material was not certified under their QSC program. The tubing in question is 1" O.D. X 0.065 inch wall thickness, ASME SA213 TYPE 316. Tube stubs from this material were welded into our valve bodies. A Liquid Dye Penetrant examination was performed on the weld area, and a hydrostatic shell test and seat test was performed after assembly. The number of valves and their serial numbers are shown on the enclosed Code Data Reports. Since the tubing is certified to ASME SA213 TY 316 and the tests mentioned above were performed, Dragon Valves. Inc. does not consider this matter to be a substantial safety hazard. The Owners (TVA) have been notified of the defect, concurrent to your notification. Sincerely, DRAGON VALVES, INC.
