About this file
This Task Group Instruction (TGI) details an inspection procedure for a 5-inch lift check valve in the 1A Boiler Economizer Outlet Feed Water System on the USS Blue Ridge, scheduled for work between July 21, 2026, and November 21, 2027. The specific valve (Valve No. V12) is manufactured by Anchor/Darling Valve Co., made of cast carbon steel with a pressure seal bonnet, and requires a comprehensive mechanical and visual inspection process including disassembly, cleaning, liquid penetrant testing, and reassembly with a new pressure seal ring.
The document outlines detailed technical requirements for the valve inspection, including torque testing of body-bound studs, verifying stainless steel inlay conditions, and attaching a label plate to the valve bonnet. SRF-JRMC will provide supporting services such as crane and rigging, utility services, and safety inspections. The Task Group Instruction references multiple technical documents and drawings for guidance, and specifies cleanliness standards for piping system/equipment at Level II. The work is part of a Boiler Inspection and Repair Management Information System (BIRMIS) report from October 17, 2024.
