SA 312 PIPE WITH LESS THAN MINIMUM WALL THICKNESS BY ITT GRINNELL 10CFR50.55(e) REPORT NO. 1 (INTERIM)

NCR-8 Description of Deficiency During normal shop inspection, several pieces of SA 312 (10-3/.4" x .365")

pipe supplied by ITT Grinnell of Kernersville, North Carolina,

, were found with wall thicknesses adjacent to the seam weld less than the minimum allowed by the ASME specifications governing wall thickness.

These pieces were made from pipe supplied to ITT Grinnell by Swepco Tube.

j Corporation, Clifton, New Jersey. Fifty-five spools and 342 feet of loose material were shipped to the site before discovery of this problem.

Interim Progress All material identified was ultrasonically inspected in the field. The inspection was performed on the longitudinal seam welds by ITT Grinnell personnel. A total of ten fabricated spools and five random lengths of loose material were identified as being below minimum wall thickness.

, After consulting with ITT Grinnell, all the loose material at the jobsite was replaced by the original material supplier. TVA was also informed that the defective sections within the fabricated spools would be cut out

and returned to Swepco to be rewelded.
