This type of grooving drill pipe is used to form a spiral groove on the rod body of the geological outer flat drill pipe, and the unprocessed drill pipe body part forms a spiral thrust, so as to achieve the function of efficient drilling and slag discharge. The product is made of special alloy steel pipe, the joint is made of high-quality alloy structural steel, the rod body is made of thickened alloy steel pipe, the joint is made of high-quality alloy structural steel, the rod body is made of thickened alloy steel pipe on the basis of high torque performance of geological drill pipe, and is formed by processing and welding single spiral blade or double spiral blade through prestressed winding process. The joint is treated by vacuum conditioning, which greatly improves the fatigue strength and shear strength. Shandong Yiguang Drilling and Mining Section

Shandong Yikuang Drilling and Production Technology Co., Ltd. produces various geological drill pipes, spiral drill pipes, triangular heavy-duty grooved drill pipes, special-shaped multi-angular grooved drill pipes, coal drill pipes, drill bits,drill pipeWait, complete specifications!

The drill pipe adopts advanced friction welding production process, which makes the drill pipe have the characteristics of high bending strength and firm welding. The drill pipe can ensure the requirements for straightness when drilling deep holes, and the structure design of large pitch and compound lead of double helix or multi-helix is adopted to optimize the drilling slag discharge performance of the drill pipe, and the drill pipe body adopts thickened geological alloy steel pipe.

Slot drill pipe has the following advantages compared with rib drill pipe:

1. The whole drill pipe is of large hole structure, which is conducive to wind pressure or water pressure drilling.

2. The outer diameters of the rod body 1, the male connector 2 and the female connector 3 are the same, which reduces the powder discharge resistance during drilling;

3. The spiral groove on the drill pipe is directly processed on the drill pipe body by mechanical processing methods such as milling. Compared with the welded spiral drill pipe in the prior art, the overall mechanical performance of the spiral blade is improved, thereby improving The wear resistance and service life of the drill pipe;

4. The number of spiral groove heads of the drill pipe is 3, the lead range is 200mm-1000mm, and the width of the spiral groove is greater than 20mm, which is conducive to the rapid discharge of pulverized coal out of the hole and improves the drilling efficiency of the spiral drill pipe;

5. The structural design of the wide blade can realize the direct clamping of the drill pipe by the rotary device and the clamp and the mechanical unscrewing of the drill pipe, and also reduce the scraping of the inner wall of the drill hole, improve the hole-forming rate of the spiral drilling, and adapt to the requirements of the soft and outburst coal seam spiral drilling process;

6. The integral three-head large-lead wide-wing spiral drill pipe is welded by friction welding, which improves the welding strength of the drill pipe.
