Introduction of 1. Geological Spiral Drill Pipe
Geological spiral drill pipe is based on the high torque performance of geological drill pipe, using single spiral blade or double spiral blade, processed and welded by prestressed winding process. The drill pipe body is made of high-quality geological special alloy steel pipe, and the drill pipe joint is made of high-quality alloy structural steel. After vacuum conditioning, the fatigue strength and shear strength are greatly improved. Using advanced friction welding production process, the drill pipe has the characteristics of high bending strength and firm welding. The production equipment completely adopts advanced CNC processing equipment, which has the characteristics of high production efficiency and stable quality. It can ensure the requirements for straightness when drilling deep holes. The ultra-low spiral spiral blade design makes the product have the characteristics of large torque, fast slag discharge speed, good drilling and forming, and not easy to get stuck. It is especially suitable for deep hole drilling of soft coal seams and coal-like rocks with poor drainage effect.
The geological spiral drill pipe with a diameter of 73 or less can be used directly with various full hydraulic drilling rigs. The drilling rig is used to directly clamp the spiral outer circle of the drill pipe for drilling and replacing the drill pipe, which is convenient and quick, and greatly reduces the labor intensity of the operator. In the drilling under the condition of ultra-loose and soft high-pressure coal seam, when the set drilling construction technology is adopted, the large spiral geological drill pipe with a diameter of 90,113,133,146 can be selected to conveniently realize the laying and installation of the core pipe. This series of products provides a guarantee for efficient deep hole drilling in mines and fills the domestic gap.
2. instructions for use
1. The drill pipe shall be maintained regularly, and the maintenance period shall be determined according to the use environment and air humidity, and the anti-rust oiling and dustproof treatment shall be carried out regularly. 2. The use of drill pipe shall be within the rated drilling distance of the drilling rig, and the matching drill pipe shall be selected according to the technical parameters of the drilling distance and the model of the drilling rig. 3, geological spiral drill pipe series products are based on the high torque performance of geological drill pipe, using single spiral blade or double spiral blade, through the prestressed winding process processing and welding. The special geological drilling pipe for mining geology is friction welded with its matching joint, so it has good follow-up and high tensile strength, and can be adapted to the efficient deep hole drilling in the mine. When working in hard rock, coal seam or other special environment, it is necessary to determine the reasonable drilling depth according to the physical properties and parameters of the actual material of the drill pipe. 3. When the drill pipe and the drill bit are used together, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the condition of the drill and the drill pipe should be paid attention to at all times during the drilling process. In case of sticking, locking, etc., stop drilling immediately or drill slowly after returning to ensure that the drill pipe is not bent and deformed. 4. When the drill pipe is ventilated or ventilated, the drill pipe shall be tightly connected during drilling. When the drill pipe has a seal, such as O-ring seal, pay attention to the use of the seal, in the event of damage, corrosion and other phenomena, to replace the seal in time. After the drilling is completed, do maintenance and cleaning work on the seal. 5. When drilling, the drill pipe should be connected manually and correctly to ensure close cooperation. It is not possible to directly drill the drill pipe to prevent damage to the drill pipe. 6. If the bending degree of the drill pipe after use exceeds the standard requirements or the thread damage causes the normal operation to be impossible, the drill pipe shall be scrapped or returned to the factory for repair in time. 7, according to the standard requirements, should ensure that the drilling depth of the drill pipe meets the relevant requirements of geological drilling to prevent the drill pipe due to the drilling depth to reach the use limit of the drill pipe, the occurrence of falling off phenomenon. 8. When working in acid and alkali areas, it is necessary to pay attention to the corrosion effect on the drill pipe. When drilling is completed, clean the surface of the rod body with clean water in time to remove the corrosion layer. 9, drill pipe should be stored in a dry place, the bottom should be multi-point support, long-term storage to deal with the drill pipe regular maintenance. 10. The drill pipe shall not be used as a supporting platform for heavy tail stacking, and the drill pipe shall not be randomly placed under gravel, coal pile or scattered pile. 11. Drill pipe maintenance After derusting/dust cleaning, protective caps should be buckled or packed and sealed to ensure that the drill pipe is usually new.
