Geological spiral drill pipe: also known as rib drill pipe, low guide vane drill pipe, spiral drill pipe, groove drill pipe.
Geological spiral drill pipeAlso known as rib drill pipe, low guide vane drill pipe, spiral drill pipe, groove drill pipe, is based on the high torque performance of geological drill pipe, adding spiral blades to improve the slag discharge performance and deep hole depth.
Product use:It is suitable for deep hole drilling construction with medium hard and above geological conditions.
The main body of the drill pipe is made of special alloy steel pipe for geology, and the joint of the drill pipe is made of alloy structural steel, which is manufactured by high pressure forming, vacuum tempering treatment, friction welding and overall surface hardening. The thread processing adopts automatic processing equipment to ensure the processing accuracy of the product. It has the characteristics of high bending resistance, firm welding and high slag discharge efficiency. Compared with similar products, the fatigue resistance and shear resistance are greatly improved.
The differential design of the spiral blade structure has a wider scope of application to the drilling geological conditions, the structural design of the high spiral blade is suitable for the deep hole drilling construction of the medium-hard and above geological conditions, and the structural design of the low spiral blade is suitable for the drilling of soft geological conditions and soft coal seams and the drilling construction of gas drainage. It has the characteristics of high slag discharge, high hole rate of drilling, and not easy to get stuck.
