Non-conductive compound containing natural extreme pressure and anti-wear additives. These are blended into JET-LUBE's all-weather calcium complex base grease. HDD ENVIRONMENTAL’s base grease offers the additional advantage of low temperature application and service, superior adhesion to wet steel surfaces, resistance to water wash-off, and most drilling muds. HDD ENVIRONMENTAL's pumpability makes it ideal for HDD and other construction drilling applications.
HDD ENVIRONMENTAL’s solids package is formulated to prevent excessive circumferential makeup by
increasing the coefficient of friction 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. HDD Environmental, with frictional properties similar to KOPR-KOTE®, has been designed to utilize the makeup charts in API RP7G by multiplying the listed torque by 1.15. Premium drill string connections such as HITORQUE® (HT), extreme® Torque (XT®), and XT-M™ connections, etc., utilize make-up torques based upon thread compound friction factors of 1.0. Therefore, use the torque provided by the premium connection manufacturer. Adjusting make-up torque based on thread compound friction factor may still be advised.
