Body grooved drill pipe is also known as body type rib drill pipe, grooved drill pipe, body grooved drill pipe, wide wing spiral drill pipe, hard rock drill pipe.

Body grooved drill pipeAlso known as body type rib drill pipe, groove drill pipe, body groove drill pipe, wide wing spiral drill pipe, hard rock drill pipe.

Product model:

The body-type wide-wing spiral drill pipe produced by our company has been serialized. The main models are: Φ50mm, Φ63.5mm, Φ73mm, and the common lengths are: 750mm, 800mm, 1000mm, 1500mm. The rod body is made of R780 geological alloy steel pipe, and the joints at both ends are made of 42CrmoA alloy structural steel friction welding. On the milling groove, there is a groove, two grooves, three grooves, three grooves are more common. In terms of wall thickness: Φ50 grooved drill pipe has 10 wall thicknesses, and Φ63.5 and Φ73 grooved drill pipes have 12 wall thicknesses.

Connection form:

The main body grooving drill pipe is mainly conical buckle, which can be selected and matched with various buckle types. Take Φ73mm grooving drill pipe as an example, the commonly used buckle types are 50, 53, 57.8 and 60. Among them, the 57.8 flat buckle is a special buckle type for large diameter lower screen pipe drill pipe. From the process design, practical application and feedback from customers in each mining area, the effect of 53 buttons is better.

The main body grooving drill pipe has fast slag discharge speed and small rotation resistance during drilling construction. At the same time, it has the strength performance of geological drill pipe and good slag discharge effect. Due to the large lead and plane structure design of the spiral blade, the phenomenon of drill pipe locking and drilling tool loss is greatly reduced under the soft coal seam and impact ground pressure strip. In addition, due to the wide spiral blade of the rib drill pipe, the rib drill pipe will not cut the hole wall of the drill hole during the drilling construction, and will not cause the deflection of the hole wall and affect the drilling effect;
