Thick spiral drill pipe/Groove drill rod

Connection type:

Grooved drill pipes are mainly tapered buckles, and a variety of buckle types can be selected and matched. Taking Φ73mm grooved drill pipe as an example, the commonly used buckle types include 50, 53, 57.8, and 60. Among them, the 57.8 flat buckle is a special buckle type for large diameter screen pipe drill pipes. Judging from the process design, practical application and feedback from customers in various mining areas, the effectiveness of 53 buckles has been proven.

Product Usage

Application fields: The application scope of the body-type wide-fin auger drill pipe is basically the same as that of the rib drill pipe. The rib drill pipe has small rotation resistance during drilling construction, and at the same time has the high strength performance of the geological drill pipe and good slag discharge effect. . Since the spiral blades adopt a large lead and planar structure design, the phenomenon of drill pipe locking and drilling tool loss is greatly reduced under conditions of soft coal seams and impact ground pressure. In addition, due to the wider spiral blades of the rib drill pipe, the rib drill pipe will not cut the hole wall during drilling, and will not cause the hole wall to deflect and affect the drilling effect. When drilling in hard and complex formations, the wear of the spiral blades is greatly enhanced, which affects the slag discharge effect and the strength of the drill pipe. Currently, the body-type wide-fin spiral drill pipe is gradually replacing the ribbed drill pipe.

Product Advantage

The rib drill pipe has fast slag discharge speed and low rotation resistance during drilling construction. At the same time, it has the high strength performance and good slag discharge effect of the geological drill pipe. Since the spiral blade adopts large lead and planar structure design, it can be used in soft coal seams and The phenomenon of drill pipe locking and drilling tool loss is greatly reduced under the condition of impact ground pressure. In addition, due to the wider spiral blades of the rib drill pipe, the rib drill pipe will not cut the hole wall during drilling construction, and will not cause the hole wall to deflect and affect the drilling effect;
