1. The Standard Structure and Function of Geological Drill Pipe Geological drill pipe is a crucial drilling tool used in the field of geological exploration. It is designed to transmit the torque generated by the drill to the bottom bit, enabling efficient drilling operations. Additionally, it serves the purpose of transferring drilling fluid between the surface and the bottom of the borehole. The drill pipe is made from high-quality alloy steel, ensuring its durability and strength. It is thickened at both ends, with small pitch taper thread, and connected using a lock joint, providing a secure and stable connection. The length of the drill pipe can vary from 1 meter to over 4 meters, depending on the depth of the drilling operation. The versatility of the drill pipe is further enhanced by its availability in different sizes, making it suitable for various drilling applications. 2. Technical Parameters and Applications of Geological Drill Pipe Geological drill pipe is available in various diameters and lengths, depending on the specific requirements of the drilling operation. Some of the common technical parameters include: * No. 1: diameter 34mm, length 500-3000mm * No. 2: diameter 42mm, length 500-3000mm * No. 3: diameter 50mm, length 500-3000mm * No. 4: diameter 63.5mm, length 500-3000mm * No. 5: diameter 73mm, length 500-3000mm * No. 6: diameter 89mm, length 500-3000mm * No. 7: diameter 35mm, length 500-3000mm * No. 8: diameter 42mm, length 500-3000mm * No. 9: diameter 50mm, length 500-3000mm * No. 10: diameter 60mm, length 500-3000mm The drill pipe is commonly used in the exploration and drilling of clays, rocks, and sands. The 50mm diameter drill pipe has a particularly wide application range and is considered more practical for such drilling operations.
3. Common specifications and materials of geological drill pipe: Generally, it has a diameter of 42x760, 42x800, 42x1000, 42x1500, 42x2000, 42x2500, 50x800, 50x1000, 50x1500, 50x2000, 50x3000, With a diameter of 63.5X1000, 63.5X1500, 73X1000, 73X1500 and other major specifications. The normalizing + tempering heat treatment process used in the drill pipe with the common model specification of R780(42MnMo7) in China has excellent mechanical properties and is suitable for higher level drilling requirements. We can also according to their own needs to manufacturers tailored. Second, the quality and process of geological drill pipe good materials and processes determine the quality of the product, so when purchasing geological drill pipe, we must first look at its raw material composition. High-quality geological drill pipe, the raw materials used are purchased from regular large-scale steel mills at home and abroad, high-quality seamless steel pipe, the production process used in steel pipe is based on the most recognized hot rolling or cold drawing process in the industry, and the steel pipe production procedures of these steel mills have very strict production process and supervision. Ensure that every steel pipe delivered is of high quality. The drill pipe processing technology of high-quality manufacturers is worth learning from. They first increase the wall thickness of the pipe end by medium frequency heating and hydraulic upsetting, and then thread processing and appropriate process treatment. In these processing processes, they will strictly control each step to further ensure the quality of the product, which is worth considering.
