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

(1) standard operation: in the construction, the drill pipe should be used in strict accordance with the tension, torque and curvature diameter allowed by various drill pipes. For construction enterprises, abnormal failure of drill pipes can be effectively avoided only when drill pipes are used according to specifications. (2) Function of transition rod: during reaming and pipe drawing, the curvature diameter of the drill pipe connected with the reaming drill bit is likely to be much smaller than the designed curvature radius of the borehole), thus causing the drill pipe to be subjected to greater cyclic stress under the action of rotating and pulling force, causing fatigue damage, in turn, cracks and fractures occur. This kind of fracture mostly occurs between 03~0.8m from the male joint of the drill pipe. In
