Material:
The geological drill pipe body is made of special alloy steel pipe for geological purposes. The material of the steel pipe is divided into two types of steel (R780 and DZ50). The material of the geological drill pipe bit is made of good alloy structural steel (42CrMo), which has been treated with vacuum air conditioning, which greatly improves the fatigue resistance. strength and shear strength.
Production Process:
The geological drill pipe is produced and processed by the advanced friction welding process. The drill pipe has the characteristics of high bending strength and firm welding, which can ensure the straightness requirements when drilling deep holes, and has high fatigue resistance and long service life.
