PIPEFITTINGS MANUFACTURED FROM UNACCEPTABLE MATERIAL Description of Circumstances:
Liberty Equipment and Supply Company of Kennewick, Washington and Tube Turns Division, Chemetron Corporation of Louisville, Kentucky reported on April 4 and 12, 1972, respectively, that potentially defective pipe fittings were manufactured frce material with a high carbon content beyond the range allowed by ASTM A-234 WPB.
These high carbon content fittings may crack when welded.
Tube Turns received 3.500 OD x.250W pipe from U. S. Steel - Lorain -
identified as U. S. Steel Heat No. N570028.
A total of 28,153 feet was received and identified by Tube Turns as Lot W6719.
U. S. Steel has not been able to determine the exact number of lengths of pipe of incorrect chemistry, but indicated it could be at least four lengths. From this pipe, 4" - 90 degrees and 45 degrees
.237 wall elbows and 2"
.237 vall straight tees, ASTM A-234.;PB, were produced by Tube Turns.
Each length of pipe is twenty feet and makes from 20 to 30 fittings. Approximately 27,000 fittings were produced and each is identified by Tube Turns Lot No. W6719.
Shipment of thece fittings started in March of 1978, and it is estimated all were shipped before the end of 1978.
On May 10, 1979, the Tube Turns Division reported to the NRC that 4" elbows, Lot W6719, have been provided to the nuclear power plants listed below.
U.S.
Steel has tested about one hundred and fifty (150) loose and installed fittings at the seven sites noted by an asterisk.
- Grand Gulf
- Zimmer
- Phipps Bend
- Waterford III
- Brown's Ferry Midland Limerick Shoreham
- LaSalle Sequoyah
- Brunswick Hartsville Bellefonte On June 1, 1979, the Tube Turns Division reported to the NRC via telephone that of the 160 fittings tested at Nuclear Power Plants, three (3) pieces were found to have a high carbon content and were replaced.
All construction permit holders are advised to conduct a review of their pipefitting receiving documents for the 1;;~ ~
