3. Advantages of friction welding drill pipe:
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, 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.
Horizontal directional drilling(HDD) drill pipe is widely used in municipal engineering like mining, bridge, tunnel, high way, railway, hydro-power.
4.Characteristics of Water Well Drill Pipe
1. The rod material of the drill pipe is made of STM-R780 material, which has stable and reliable performance. The end is heated by intermediate frequency, hydraulically upset, and heat treated, which effectively eliminates the internal stress of pre-processing.
2. The tool joints are made of 42CrMoA material, which is quenched and tempered after rough machining, and subjected to surface nitriding treatment after finishing.
3. The threads are all cut and formed by CNC lathe forming inserts, with precise coordination and strong interchangeability.
