Down-the-hole drill pipe plays an important role throughout down-the-hole drilling (regardless of application, rock type, drilling depth, or drilling rig). The key features of high-quality down-the-hole drill pipe are durability, accuracy and manageability. The down-the-hole drill pipe is made of high-quality alloy, and the seamless steel pipes at both ends are connected by friction welding. During operation, high-pressure air is transported to the down-the-hole impactor through the down-the-
Down-the-hole drill pipe plays an important role throughout down-the-hole drilling (regardless of application, rock type, drilling depth, or drilling rig). The key features of high-quality down-the-hole drill pipe are durability, accuracy and manageability. The down-the-hole drill pipe is made of high-quality alloy, and the seamless steel pipes at both ends are connected by friction welding. During operation, high-pressure air is transported to the down-the-hole impactor through the down-the-hole drill pipe, and at the same time, rotation and pressure are transmitted to the down-the-hole impactor.
