SSTG Lift Rod Thermal Spray

Trident Refit Facility, Bangor, WA (TRFB), in support of Trident Submarines, requires commercial Thermal Spray services. SSTG Lift Rods, when ordered are not thermal sprayed. EM 841/322M-11 allows repair/modification of Lift Rods by coating the bushing seal area with ceramic. The ceramic modification will allow a tighter clearance without galling so that steam leakage can be reduced and galling normally seen on these Lift Rods can be eliminated. Vendor will pre-machine as required to apply sufficient amount of thermal spray. Vendor will prepare surface (pre-grind) and apply thermal spray. Process IAW NAVSEA T9074-AA-GIB-010/1687 to (10EA) Lift Rods (provided by NAVIMFACPACNORWEST). Vendor will rough grind the coated Lift Rods to a rough diameter of 1.260”/1.261” IAW EM 841/322M-11.
