What is the material of the geological drill pipe?
The drill pipes produced by our company are all made of high-quality steel, of which the Φ 34mm-50mm geological drill pipes are made of DZ50(45Mn2), those above Φ 50mm are made of R780(36Mn2v, 42Mnmo7), and the joints are all made of 42crmoA. Spiral drill pipes include geological spiral drill pipes with the same material as geological drill pipes, and spiral blades (strip steel) are made of Q235 and 16 manganese, other types of spiral drill pipe use high pressure seamless steel pipe as the main material for processing.

How to distinguish the product name of geological spiral drill pipe geological spiral drill pipe thread form thread connection/hexagonal plug connection/sealing thread connection male and female connection application fields rock drilling engineering and geological exploration geological spiral drill pipe is a drill pipe that achieves deep hole drilling and efficient slag discharge performance after reprocessing spiral blades on the basis of high torque performance of geological drill pipe, which is called geological spiral drill pipe, also known as rib drill pipe, low guide vane drill pipe, spiral drill pipe, wide blade drill pipe, double wire drill pipe, body groove drill pipe, etc. The commonality between geological spiral drill pipe and geological drill pipe is that both kinds of drill pipes are used for water exploration in coal roadways.
