NCS-30® Nonconductive Thread Compound - NSF H2

NCS-30® is a premium quality, nonmetallic compound containing carbon based fibers and additives, and other natural extreme pressure and anti-wear additives. These are blended into our high temp calcium complex base grease. This base grease offers the additional advantage of superior adhesion to wet steel surfaces, resistance to water wash-off, and most drilling muds. It's especially effective for invert or high-pH muds. NCS-30 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. NCS-30, with frictional properties similar to KOPR-KOTE®, has been designed to utilize the makeup thread manufacturer’s torque multiplied by its 1.15 friction factor on API connections. Premium drill string connections such as HI-TORQUE® (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. Friction factors for NCS-30® were developed using full scale API tool Joint connections. • Designed for optimum performance on all rotary-shouldered connections such as Tool Joints and Drill Collars. It can also be used on premium/proprietary thread designs such as Double-Shouldered, Wedge Thread™*, and other types of mechanical seal designs. It may also be used on certain non-interference tubing thread designs when properly torque compensated. Note: For a “Yellow”-rated product, use NCS-30® ECF™.
