ACCESSION #: 9502170233 CRAWFORD FlTTING COMPANY SOLON, OHIO 44139 FRED A. LENNON PHONE (216) 248-4600 CHAIRMAN FAX (216) 349-5970 February 7, 1995 Document Control Desk Office of Nuclear Reactor Regulation Nuclear Regulatory Commission Washington, DC 20555 Subject: Defects Potentially Reportable under 10CFR21 Gentlemen: We are writing to inform you about a possible material defect in stainless steel Swagelok tube fittings or adapters. The body of the fitting in question is stamped with the heat code GNM. It is only the body of the fitting that is in question. A list of the U.S. nuclear facilities to which these parts have been sold is enclosed, along with the relevant part numbers. All of these facilities have been notified by us about this possible problem. The type of defect is a strain crack, which occurs during the cold drawing process. If the geometry on the dies is not set correctly, a small length of the bar may have an area that can crack. This type of crack would already be present in the machined fitting, and if not noticed during installation, would leak immediately upon system pressurization. At this time we have only confirmed one fitting from this heat with this condition. We enclose a certified material test report from the supplier of the material, Al Tech Specialty Steel Corporation. The supplier has already instituted a program of ultrasonically tested stainless steel bars that we purchase and we believe this would aid in detecting this type of defect. We also enclose sales drawings showing the affected parts. All of the fittings in question are 1/8", 1/4" or 3/8" in size.
