High-pressure Sealed British-style Drill Pipe

The high-pressure sealed drill pipe is a primary component of integrated drilling and cutting equipment used for gas drainage holes in coal mines. It is installed at the front end of the drilling rig's power head, connecting the water cutter and the drill bit. It transmits the rotational speed and torque from the drilling rig to the drill bit and serves as a transmission part that delivers high-pressure water through a high-pressure water braid. The body of the high-pressure sealed British-style drill pipe uses high-quality alloy steel pipes specifically designed for geological exploration, while the drill pipe joints are made from high-quality 42CrMo alloy structural steel, treated with vacuum tempering. This results in a drill pipe with high pressure resistance, excellent sealing performance, high strength, and superior capabilities in transmitting rotational speed, torque, and delivering high-pressure water.

The British-style drill pipe, also known as smooth drill pipe or round drill pipe, has a rod body material designated as R780, and its drill pipe joints are made from high-quality 42CrMo alloy steel.

Product Features:
