A horizontal directional drill pipe is a drilling tool used to transmit the torque and tension of the rig during directional
drilling construction. Since it needs to withstand twist, tension, bending, friction and vibration during directional
construction, its manufacturing process needs to be very strict. The drill pipe is classified into friction welding drill pipe andoverall welding drill pipe.

The raw materials of drill pipe are alloy structural steels produced by Baosteel for geology. After testing, the two pier ends of the pipe are thickened directly without welding. Then the steel pipe with a thick pier is subjected to overall heat treatment, and nickel-phosphorus is added to increase the hardness and tightness of the thread surface. Before the finished drill pipe is painted and packaged, a series of tests are performed, including hardness, metallographic structure, and physical properties.

To guarantee premium quality product, all products material is sourced from Shanghai Baosteel specially developed hot rolling high strength alloy structure tube for oil and gas drilling tools without considering about high cost.


This material uses external refining and vacuum degassing technology with even composition and high purity. The lowest content of harmful chemical elements such as phosphor and sulfur is reached.


Non destructive test is performed according to NDT standard Level 2 with combination of eddy and ultrasonic to guarantee material quality without any defect.


Each of  drill pipe is treated by shot peening. After shot peening treatment, surface of drill pipe and thread gets residual pressure stress. This stress can improve drill pipe anti-fatigue service life. Shot peening treatment on thread can help thread compound adhering to thread. Thread service life is improved.


Product Application

HDD drill pipe is a tool applicable for transferring torque and tension of drillers in the process of directional drilling construction. Due to the fact that it has to bear torsion, tension, bending, friction and vibration in the process of directional construction, the requirements for processing process are very strict.

The raw materials selected by our company are all the alloy structure steels for geographical usage produced by Baogang Steel. After laboratory tests, both ends of a pipe are upsetted and proceeded to overall heat treatment, then friction welded. Before finished drill pipes are plated and packaged, a series of tests have to be implemented including hardness, metallurgical structure, physical performances, etc.
