20555 March 12, 1979 IE Bulletin No. 79-03 LONGITUDINAL WELD DEFECTS IN ASME SA-312 TYPE 30h STAINLESS STEEL PJPE SPQ0LS MANUFACTURED BY YOUNGSTOWN WELDING AND ENGINEERING COMP R Description of Circumstances:
27, 1978, the Arizona Public Service Co=pany reported that On September defects had been discovered in longitudinal velds in ASME Section III class 2 pipe supplied for the Palo Verde Nuclear Generating Station (PVNGS). On November 17, 1978, the Southern California Edison Company reported similar defects in pipe supplied for the San Onofre Nuclear Generating Station, Units 2 and 3.
Pullman Power Products of Los Angeles, California supplies safety-related fabricated piping spools of various diameters for the PVNGS.
The defects were discovered by Pullman in ASME SA-312 type 30h stainless steel pipe supplied to Pullman by Youngstown Welding and Engineering Company of Youngstown, Ohio. The pipe is manufactured by rolling plate into cylinders and then fusion velding the longitudinal seam without filler metal.
Pullman discovered defects in the longitudinal velds while radiographing their circumferential shop velds. Further radiographic examination of the longitudinal velds revealed rejectable porosity and lack of fusion.
Pullman then performed ultrasonic examination of the full length of the longitudinal velds and discovered indications exceeding the acceptance criteria of ASME Section III. Further ultrasonic examination revealed indications in other piping subassemblies where pipe was supplied by Two indications verified by radiography were identified as Youngstown.
porosity and measured 0.350 inch by 0.125 inch in one case and 0.300 inch by 0.125 inch in another case in pipe with a nominal vall thickness of 0.375 inch.
The additional examinations revealed that of 103 spools and four pipe supports shipped to PVNGS, kh spools and one pipe support were found to contain ultrasonic indications exceeding those permitted by the AS!E Of 65 partially fabricated piping spools, 30 were found to be Code.
The acceptance criteria for the pipe supplied by similarly defective.
Youngstown includes 100 percent ultrasonic examination of the longitudinal 1 of 3 7903160138
