Tool wrench for 76mm drill pipe
The downhole drill pipe products are made of high-quality materials,the heat treatment of the materials is carried out by an integrated multi-functional furnace,all threads are processed by professional numerical control,the internal part of the end of the rod body is thickened,the strength of the weld joint is greatly improved,and the tempering treatment is carried out after friction welding,so that the quality of the drill pipe is stable and reliable,and the service life is greatly prolonged.
Products feathers:
DTH Drill Pipe (No Flat) for mining is a multi-functional system combining rock drilling, slag removal, hole stabilization, and quick-change. It is compatible with various drilling tools such as hydraulic top hammer drills (DTH), down-the-hole hammers, and roller cone bits, meeting the needs of complex working conditions such as bench drilling in open-pit mines, underground tunnel excavation, and slope anchoring, significantly improving the operating efficiency and equipment utilization of the integrated drilling machine.
DTH Drill Pipe (No Flat) for mining is a specialized drilling tool for use with fully hydraulic open-pit drilling rigs, tracked down-the-hole drilling rigs, and other equipment, widely used in mining blasting holes, slope anchoring, geological exploration, and other fields. Designed for complex geological formations and high-intensity operations, our company's integrated drilling rod for mining possesses high strength, high precision, and high wear resistance, ensuring long-term stable operation in harsh environments. The rod body and joints are manufactured using integral forging or friction welding processes, resulting in high strength, excellent tensile and torsional resistance, and resistance to breakage. High-strength alloy steel is selected and subjected to heat treatment, providing excellent fatigue and impact resistance. The thread machining precision is high.
