Product advantages
The main body of the drill pipe is made of high-quality geological special alloy steel pipe, and the drill pipe joint is made of high-quality alloy structural steel. The machining accuracy of the products, the production process of friction welding first and then thread processing, ensures the coaxiality standard of multiple connections of drill rods when deep hole drilling. stability, etc.
Connection Type
Buckle type: flat buckle, taper buckle
Flat buckle: Φ34.0mm, Φ42.0mm, Φ50.0mm (drill pipe diameter)
Taper buckle: Φ63.5mm, Φ73.0mm, Φ89.0mm (drill pipe diameter)
Flat buckles are generally used for small diameter geological drill pipes. With the increase of the diameter of the drill pipe, the drilling depth and the torque of the drill pipe will increase accordingly. The drill pipe connected by the taper can ensure the transmission of torque when the drill pipe is working, and it is also more convenient to disassemble. It can also be customized according to the special needs of customers.
