Overview/drill pipe
Drill pipe plays an important role in the drilling process. It transmits the torque of the drilling rig to the drill bit to realize drilling. In the drilling, the drill pipe is subjected to a very complex load, almost at the same time under the tension, compression, torsion, bending and other stress, the quality of the drill pipe is very important for drilling work. Shandong yiguang drilling and mining technology co., ltd. adopts the process of friction welding before threading in the manufacture of drill pipes, which ensures the coaxiality of multiple connections of drill pipes, and carries out joint nitriding process on the male head of drill pipe, which not only makes the joints more wear-resistant but also effective.SolveThe common gluing problems are solved, and the comprehensive service life is greatly improved.
Technical features/drill pipeEdit
The drill pipe body is made of high-quality geological special alloy steel pipe, and the drill pipe joint is made of high-quality alloy structural steel. After vacuum conditioning, the fatigue strength and shear strength are greatly improved. The use of advanced friction welding welding process production and processing, drill pipe with high bending strength, welding firm and so on. The production equipment completely adopts advanced CNC processing equipment, which has the characteristics of high quality and stable production efficiency. It can ensure the requirements for straightness when drilling deep holes, and the product has high fatigue strength and long service life.
Classification/drill pipeEdit
The drill pipes produced by Shandong Yikuang Drilling and Production Technology Co., Ltd. are divided into geological drill pipes, geological spiral drill pipes, high-efficiency spiral drill pipes, triangular drill pipes, triangular heavy-duty grooving thrust slag discharge drill pipes, body rib drill pipes, new coal drill pipes, anchor cable drill pipes, air drill pipes and other series of products.
