Kelly Drive Bushings • HDP, HDS

Torque Transmission: Kelly Drive Bushings serve as a connection point between the rotary table and the drill string, allowing torque generated by the rotary table to be transmitted to the drill string. This torque is necessary for rotating the drill string and the drilling bit to penetrate the subsurface formations.
Compatibility: Kelly Drive Bushings come in different designs and configurations to accommodate various types of drill string connections, such as Hex Pin and Square Pin. This ensures compatibility with different types of drilling equipment and drill string components commonly used in the industry.
Enhanced Stability: The HDP and HDS variations of Kelly Drive Bushings are designed to provide enhanced stability and durability during drilling operations. The Hex Drive Pin and Hex Drive Square designs offer a secure connection between the rotary table and the drill string, minimizing the risk of slippage or disconnection during high-torque drilling operations.
Reduction of Wear and Tear: By effectively transferring torque from the rotary table to the drill string, Kelly Drive Bushings helps reduce wear and tear on other components of the drilling equipment, such as the rotary table drive system. This prolongs the lifespan of the equipment and reduces maintenance costs.
Increased Efficiency: The efficient transmission of torque provided by Kelly Drive Bushings contributes to increased drilling efficiency. It allows drilling operations to proceed smoothly and consistently, minimizing downtime and maximizing the rate of penetration into the subsurface formations.
Safety: Kelly Drive Bushings are designed to meet stringent safety standards and regulations in the oil and gas industry. By providing a reliable connection between the rotary table and the drill string, they help ensure the safety of rig personnel and equipment during drilling operations.

Overall, Kelly Drive Bushings, whether in HDP or HDS variations, with Hex Pin or Square Pin designs, are essential components that enhance oil drilling operations by facilitating the efficient transmission of torque from the rotary table to the drill string, ensuring compatibility, stability, and safety during drilling activities.
