About this file
This is a Job Specification document for ship maintenance work on the USS SAN DIEGO (LPD-22). The work involves the removal and installation of a refrigerant suction pipe for the No. 4 Air Conditioning Plant located in Auxiliary Machinery Room No. 2.
The scope of work includes removing the existing 8-inch IPS refrigerant suction pipe (which has a pin hole defect) from the compressor suction system, delivering it to SRF Production Shop S56 for repair under separate job order 38DXA51413-H01, and subsequently reinstalling the repaired pipe. Installation requirements include cleaning and preparing all surfaces, reusing existing fasteners, installing new gaskets, and witnessing an operating pressure test to verify joint tightness with zero allowable leakage. The work references Air Conditioning Plant technical drawings S9514-D5-MMA-010 Rev 17 and parts list 476-84001-000 Rev M. The document specifies that Ship's Force will handle refrigerant recovery, evacuation, dehydration, charging, and system adjustment. Government-furnished materials include gaskets, bolts, screws, insulation sheets, glass cloth, and adhesives identified in the material list. The preparing activity is SASEBO, with an anticipated award date of 11/03/2026 and production completion date of 01/31/2027. The SRF Production Shop point of contact is Mr. Tanaka at extension 252-8192.
