Friction welding drill pipe is a steel pipe with a grain at the tail, which is used to connect the surface equipment of drilling rig with the drilling and grinding equipment or bottom hole device at the bottom of drilling. The purpose of the drill pipe is to transport drilling mud to the drill bit a

As for friction welding drill pipe, we all know that it is a geological drilling tool designed and produced by friction welding technology with high-quality alloy steel pipe, which is used to transfer the torque of drilling rig to drill the drill pipe. There are two main points that need to be judge

Thread cracking failure accounts for about 70% of drill pipe failure. According to the analysis of the causes of thread cracking failure, the following preventive methods can effectively reduce the incidence of such failure: (1) When machining threads, it is necessary to prevent the generation of im

The reason of drill pipe cracking is that the drill pipe is a kind of steel pipe with thread at the tail, which is used to connect the surface equipment of the drilling rig with the drilling and grinding equipment or bottom hole equipment located at the bottom of the drilling. The purpose of drill p
