LUBRICATION, THREAD, CORROSION-RESISTANT STEEL AND ALUMINUM ALLOY TUBE FITTINGS, SPECIFICATION FOR
|Publication Date:||15 January 1991|
This specification defines the requirements for lubrication of stainless steel and aluminum 37-degree flared-tube fittings to prevent galling and to provide more accurate assembly torque values.
Application. - This specification shall not be used on systems requiring a cleanliness level more stringent than level 300 for particulate and level A for nonvolatile residue in accordance with KSC-(2-123, unless authorized by Engineering Development (DE).
Working Fluids. - This specification may be used for the following fluids:
a. All hydrocarbons, such as RP-1, hydraulic fluid, etc.
b. All inert fluids, such as helium and argon (both gaseous and liquid)
c. Air, nitrogen, and carbon dioxide (both gaseous and liquid)
e. Gaseous and liquid oxygen
f. Gaseous and liquid hydrogen
g. Hypergolic propellants, such as nitrogen, tetroxide,
Material Compatibility. - This specification shall be used for stainless steel to stainless steel and aluminum to aluminum joints only. Only lubricants that are oxygen compatible shall be used, except as specified in 3.1.1 and 3.1.2.
Lubrication in accordance with this specification is intended to minimize galling of mating surfaces. Strict adherence to this specification is required to prevent fluid... View More
