ABSTRACT:
A metal-free lubricant composition for use in threaded tube and pipe connections includes graphite and a substantially nonabrasive, friction increasing adjusting component, both dispersed in a lubricant base material in which a polyalkylene is dissolved, with the graphite being present in an amount effect to decrease a coefficient of friction of said composition, the friction increasing adjusting component being present in an amount effective to increase the coefficient of friction of the composition, and the polyalkylene being present in an amount effective to enhance formation of graphite flakes from graphite particles upon application of pressure. The lubricant composition can provide corrosion resistance as well as similar or superior lubricating properties in comparison to conventional metal-containing grease compositions.
