Rotary Tricone Drill Pipe
ProDrill™ Rotary Tricone Drill Pipes are made of high-quality materials, and the heat treatment of materials uses multi-functional integrated heat treatment equipment. All threads are processed with professional CNC processing equipment,and all threads are processed and tested with professional thread gauges in line with international industry standards,so the threads are closely matched and the quality of thread matching is improved to the maximum extent.The rotary tricone drill pipe is welded by submerged arc welding or friction welding. Compared with the common welding method,the submerged arc welding has deeper penetration and better weld quality after welding.
