A: We use AISI 4145H modified forged alloy steel. This material is selected for its excellent hardenability and strength, ensuring the joints can handle repeated high-torque connections without deforming.
A: Our tool joints are designed for Friction Welding. This process creates a 100% metallurgical bond that is stronger than the pipe body itself. Each weld zone then undergoes post-weld heat treatment and rigorous NDT inspection.
A: We offer a full range of API standard connections, such as NC26, NC38, NC50 (IF), and more. We also provide specialized stress-relief features like Bore Back boxes and Stress Relief grooves on the pins to enhance fatigue life.
A: Our tool joints are designed with extended tong space. This provides extra material that allows for multiple thread re-cuts, maximizing the service life of your drill pipe investment.
