JET-LUBE® KOPR EXT FF 1.0 is a modification of JET-LUBE EXTREME®. It's designed with a lower coefficient of friction to be used where rig tong and/or iron roughneck units lack the torque capacity to reach the optimum engagement of higher torque connections. KOPR EXT FF 1.0 still offers the advantage of superior adhesion, improved EP and antiwear properties, resistance to water wash-off, and superior rust and corrosion protection in the presence of invert or high-pH muds.
KOPR EXT FF 1.0 can be used for up to 6 months connection storage. The solids package is formulated to prevent wear and galling under compressive forces. As stress levels rise above 50% of yield, the friction factor increases, limiting downhole makeup. Full hydraulic joint efficiency is maintained allowing joint shoulder faces to mate completely without standoff or deformation.
Highly resistant to drilling muds
Contains no lead or zinc
Extreme pressure additives provide additional protection against seizing and galling
Complex grease base provides superior rust and corrosion protection
Sticks to wet joints
Brushable and stable over a wide temperature range
For optimum performance on API drill string connections, KOPR EXT FF 1.0 should be utilized with the torque charts in API RP7G and in extreme conditions by multiplying the listed torque value by 1.0 or by contacting the drill pipe and connection manufacturer or drill pipe owner.
