How to select drill pipe
The active drill pipe is a tool used to transmit the torque of the drill pipe to the drill pipe to achieve drilling. It is suitable for various specifications of core drills, mainly used for engineering geological exploration, hydrology, water wells and large-diameter engineering construction. In the process of purchasing, the most important thing is to see the raw materials and processing technology of the drill pipe, which is directly related to whether the drill pipe can effectively avoid fracture, water leakage, gluing, deformation, wear and other problems. With Baosteel tube as the raw material, the end of drill pipe is heated by medium frequency, hydraulic upsetting and heat treated to effectively eliminate the internal stress in the early processing. The drill pipe joint is made of 42CrMo. After rough machining, it is quenched, tempered and heat treated. After finishing, it is nitrided on the surface, which can effectively eliminate the problems of gluing and pulling, and is more wear-resistant and easy to disassemble
