Geological drilling tools designed and produced by friction welding process of geological alloy steel pipe
Material
The geological drill pipe body adopts geological special alloy steel pipe (R780, DZ50), and the geological drill pipe bit adopts high-quality alloy structural steel (42CrMo) through vacuum tempering treatment, which greatly improves the fatigue strength and shear strength.
Anchor Folding Production Process
Using advanced friction welding welding process production and processing, the drill pipe has the characteristics of high bending strength and firm welding, which can ensure the straightness requirements during deep hole drilling, and has high fatigue strength and long service life.
