Licensee Action on Previously Identified Items (Closed) Part 21 report concerning the potential for certain 4-inch steel elbows to exceed the specified carbon content. The Benjamin F. Shaw Company informed the licensee by letter dated April 17, 1979, that certain fittings with heat code W6719 might have abnormally high carbon content.
The material supplier arranged for a representative from U. S. Steel to examine the fittings at the site and reject those fittings with high carbon content.
The examination indicated a total of 26 fittings on site from heat code W6719. Tests indicated one of these 4" fittings, control No. HG2020, Fab. Mark No. 2HG02A-4"-10, exceeded the specified carbon content by a small amount.
This elbow was removed from the line and replaced with a fitting that met material specifications.
