Introduction of 1. rib drill pipe
Rib drill pipe in the construction process of small rotation resistance, good slag discharge effect, can be applied to various types of strata, and can be quickly disassembled by disassembly device, improve the construction efficiency, save labor and material costs. Because the spiral blade is wide and has high hardness, the rib drill pipe has a good slag discharge effect and is suitable for various hardness and various types of formations. In addition, due to the wider spiral blade, the rib drill rod will not cut the hole wall of the drilling hole during the drilling construction process, and will not cause the hole wall to be inclined and affect the drilling effect. Rib drill pipe is divided into taper thread connection and hexagonal quick plug type.
Instructions for use of 2. rib drill pipe
- The drill pipe shall be regularly maintained, and the maintenance period shall be determined according to the operating environment and air humidity, and the anti-rust and anti-dust treatment shall be carried out regularly.
- 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.
- Rib drill pipe series products are the use of foreign advanced technology production of right-angle large pitch drill pipe, water drill pipe spiral steel belt and rod body with special material winding and welding. The water detection drill pipe has high strength, good elasticity, not easy to bend, convenient and quick connection, and can be used with various coal electric drills or tunnel drilling rigs
- Supporting use. In the drilling construction of water and gas exploration or other special environmental operations under the geological conditions of coal seam and near coal seam, the reasonable drilling depth shall be determined according to the physical properties and parameters of the actual material of the drill pipe.
- When the drill pipe is used with the drill bit, 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.
- 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.
- The drill pipe shall be connected manually and correctly during drilling to ensure close coordination. It is not possible to directly drill the drill pipe to prevent damage to the drill pipe.
- If the bending of the drill pipe after use exceeds the standard requirements or the thread damage causes the normal operation, it shall be scrapped or returned to the factory for repair in time.
- According to the requirements of the standard, the drilling depth of the drill pipe shall meet the relevant requirements of geological drilling to prevent the drill pipe from falling off due to the drilling depth reaching the use limit of the drill pipe.
- When working in acid and alkali areas, attention should be paid to the corrosion of drill pipe. When drilling is completed, clean the surface of the rod body with clean water in time to remove the corrosion layer.
- The drill pipe shall be stored in a dry place, the bottom shall be supported at multiple points, and the drill pipe shall be regularly maintained during long-term storage.
- 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 the gravel and coal pile or randomly stacked.
- Drill pipe maintenance After derusting/dust cleaning, protective caps shall be buckled or packed and sealed to ensure that the drill pipe is normally new.
