Product Parameters :Product Parameters
Diameter: Ф34mm, Ф42mm, Ф50mm, Ф63.5mm, Ф73mm, Ф89mm
Length: 0.5m, 0.8m, 1.0m, 1.5m, 3.0m

The body type wide-foil auger rod produced by our company has been serialized:

The main models are: Φ50mm, Φ63.5mm, Φ73mm

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 friction welded with 42CrmoA high-quality alloy structural steel. In the milling groove, there are one groove, two grooves, and three grooves, and the three grooves are the most common.

In terms of wall thickness: Φ50 grooved drill pipe has 10 wall thicknesses, Φ63.5, Φ73 grooved drill pipe has 12 wall thicknesses.
Product buckle type: The grooved drill pipe is mainly conical buckle, and a variety of buckle types can be selected and matched. Take the Φ73mm grooved 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 drill pipe. Judging from the process design, practical application and feedback from customers in various mining areas, the use of 53 buckles is the best.

Product Usage

Application field: The application range of the body type wide-foil auger drill pipe is basically the same as that of the rib drill pipe. During the drilling construction, the rib drill pipe has low rotational resistance, and at the same time has the high strength performance of the geological drill pipe, and has a good slag discharge effect. . Due to the large lead and plane structure design of the helical blade, the phenomenon of drill pipe locking and drilling tool loss can be greatly reduced under the conditions of soft coal seam and rock burst. In addition, due to the wider helical blade of the rib drill rod, the rib drill rod will not cut the hole wall of the drill hole during the drilling construction, and will not cause the deflection of the hole wall to affect the drilling effect. When drilling in hard and complex formations, the wear of the helical blade is greatly enhanced, which affects the slag discharge effect and the strength of the drill pipe. The current body type wide-foil auger pipe is gradually replacing the rib drill pipe.

Product advantages

The grooved drill pipe has fast slag discharge speed and low rotation resistance during drilling construction. At the same time, it has the high strength performance of geological drill pipe and good slag discharge effect. Due to the large lead and flat structure design of the helical blade, it can be used in soft coal seams. The phenomenon of drill pipe locking and drilling tool loss is greatly reduced under the conditions of rock burst and ground pressure. In addition, due to the wider 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 to affect the drilling effect;
Drilling depth: The main body type wide-foil auger rod is mainly used for deep hole drilling between 100-300 meters, the theoretical drilling depth of the Φ50mm main body wide-foil auger pipe is 100m-150m, and the Φ63.5mm main body type wide-foil auger The theoretical drilling depth of the auger rod is 150m-250m, and the theoretical drilling depth of the Φ73mm body wide-foil auger rod is 200m-300m. The body type wide-foil auger pipe produced by our company can reach a cumulative drilling depth of more than 10,000 meters in Jixi area of Heilongjiang and Yangquan area of Shanxi.

Product Advantage

The grooved drill pipe has fast slag discharge speed and low rotation resistance during drilling and construction. At the same time, it has the high strength performance of geological drill pipe and good slag discharge effect. It adopts large lead and plane structure design, thus greatly reducing the phenomenon of drill pipe locking and drilling tool loss under the conditions of soft coal seam and rock burst. In addition, due to the wider helical 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 to affect the drilling effect;
Drilling depth: The main body type wide-foil auger pipe is mainly used for deep hole drilling between 100-300 meters, the theoretical drilling depth of the Φ50mm main body wide-foil auger pipe is 100m-150m, and the Φ63.5mm main body width The theoretical drilling depth of the vane auger rod is 150m-250m, and the theoretical drilling depth of the Φ73mm body wide-foil auger rod is 200m-300m. The body type wide-foil auger pipe produced by our company can reach a cumulative drilling depth of more than 10,000 meters in Jixi area of Heilongjiang and Yangquan area of Shanxi.
The rock drilling pipe products produced by our company are widely used in various regions at home and abroad. The main domestic application areas are: China Coal Group, Longmei Group, Shenmei Group, Fengfeng Coal Industry, Kailuan Coal Industry, Lu'an Coal Industry Industry, Yangmei Group, Jinmei Group, Xishan Coal and Electricity, Fenxi Coal Industry, Datun Coal Industry, Xinji Energy, etc.; the main use areas in foreign countries: Russia, Australia, Southeast Asia and Northern Europe.
