FIELD: engineering industry.
SUBSTANCE: invention refers to operating greases, and namely to grease used for sealing threaded connections of pump-and-compressor pipes and casing pipes. Grease consists of fat base - industrial oil, "LKS-M" complex metallurgical lithium grease and graphite, as well as fine copper powder having small flake structure, with pure copper content of 99.1%-99.7%.
EFFECT: use of proposed grease provides uniform increase of torque moment from engagement of first turns of thread, which allows increasing the number of screwings/unscrewings by many times.
