About this file
This Task Group Instruction (TGI) details a maintenance procedure for the USS Blue Ridge's 1B Boiler Desuperheater Tightness Test. The task involves installing and removing test fittings on the desuperheater outlet piping to perform a tightness test for mechanical joints, with work scheduled from July 21, 2026, to November 21, 2027. The boiler, manufactured by Foster Wheeler Corp., has a design pressure of 705 PSIG and a maximum operating pressure of 655 PSIG, located in Fire Room (8-76-0-E).
The procedure requires removing the blank flange from the desuperheater outlet piping, installing test fittings, conducting the tightness test, and then reinstalling the blank flange with a new gasket conforming to MIL-G-24716. SRF-JRMC will provide supporting services including crane and rigging, utilities (low pressure air, water, and steam), safety inspections, gas-free inspections, and quality assurance inspections. The task is in response to a Boiler Inspection and Repair Management Information System (BIRMIS) report dated October 17, 2024, with a potential asbestos hazard noted and a requirement for Level II cleanliness for piping systems and equipment.
