Friction welding drill pipe, also known as imitation British drill pipe, friction welding drill pipe body using high-quality alloy structural steel material, after non-destructive testing and performance inspection qualified rear end for rough treatment, after rough full-length heat treatment, improve the toughness and strength of the pipe body, drill pipe joints using high-quality alloy structural steel with strength better than the pipe material. The thread is made on a high-precision CNC lathe, and the thread part is heat-treated to meet the toughness requirements of the rod body and the strength requirements of the joint.
Introduction of friction welding drill pipe:
Friction welding drill pipe is also calledEnglish-like drill pipe,The friction welding drill pipe body is made of high-quality alloy structural steel material, and the rear end of the qualified non-destructive testing and performance inspection is roughed, and the full-length heat treatment after roughening is carried out to improve the toughness and strength of the pipe body. The drill pipe joint is made of high-quality alloy structural steel with strength better than the pipe body material. The thread is made on a high-precision CNC lathe, and the thread part is heat-treated to meet the toughness requirements of the rod body and the strength requirements of the joint.
Features of friction welding drill pipe:
1) The best combination of drill pipe is realized, and the rod body and joint can be made of different materials, which improves the optimization performance of heat treatment. Other forms of drill pipe cannot be realized.
2) The joint has high mechanical properties and wear resistance. Longer service life than other forms of drill pipe.
3) Light weight and good flexibility.
4) The drilling fluid channel inside the drill pipe can be designed. The design of the inner hole channel of the threaded probe can fully consider reducing the hydraulic loss when passing through, and the special city can reduce the loss caused by the threaded connector part, which can improve the working efficiency of the drilling fluid system.
5) With the improvement of welding equipment, welding process and technology, as well as the improvement of heat treatment technology, the connection strength of friction welding has been higher than the strength of the base metal itself. The welding strength of the welded seam is higher than the strength of its base metal after re-pier coarse thickening.
6) After the rod body of the friction welding drill pipe is thick, the overall quenching and tempering heat treatment is carried out, and its bending resistance and flexibility are greatly improved.
