Product Description



Name: API 5dp S135 oilfield steel drilling tool joint/Forged steel drilling tool joint
ApplicationThis DTH drill pipe, the shortened form of down the hole drill pipe, is a kind of outer flat drill rod. It is mainly used in rotary percussive drilling that contains gases and liquids. Its main components include pipe (rod) body and joint.
Our down the hole drill pipe is manufactured based on the API standards. And according to specific requirements, we also provide this kind of DTH drill pipe in different Chinese and American specifications.
As for its advantages, it has features of big rigidity, good sealing capacity, flat outer structure, and low torque and resistance when rotating.
As to the packaging, a bundle of DTH drill pipes will be packed by one set of steel frame, and a bundle will have 30 to 40 drill pipes.
