Connecting sleeve

The coupling sleeve is an indispensable component in drilling tools. During the drilling process, the coupling sleeve is located at the joint between the accompanying drilling tools and is subjected to various stresses, including axial tension and compression, bending, torsion, contact, and friction, as well as corrosive effects. The coupling sleeve uses its threads to connect two or more drill rods or tail drill rods along the same axis, transmitting the impact force generated by the rock-drilling machine and thus achieving the purpose of drilling rock holes. Like the drill rod itself, the coupling sleeve also serves as a medium for propagating stress waves. Our company conducts quality control strictly in accordance with the ISO9001 quality management system. All product specifications and parameters can be customized. We look forward to cooperating with your company.

Blast furnace drill pipe

Blast Furnace Opening Drill Rods—These blast furnace opening drill rods are suitable for use with various blast furnace opening machines and are ideal for opening furnaces in ironmaking processes, accommodating a wide range of refractory materials as well as clay-based opening tools. They boast an even broader application scope and can also be used to drill through various non-metallic materials such as rock, refractories, and clay-based sealing compounds. The blast furnace drill rods are made from alloy steel tubing, significantly enhancing their fatigue resistance and shear strength. Their primary functions include transmitting torque and conveying drilling fluids; as the drill rods gradually extend, they enable continuous deepening of the borehole. Our company conducts quality control strictly in accordance with the ISO9001 quality management system. All product specifications and parameters can be customized. We look forward to collaborating with your company.
