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, the new coal drill pipe series products are based on the original old twist coal drill pipe, using high-quality steel pipe andTThe welded steel strip structure is manufactured by advanced prestressed winding welding process. This product has a light weight(Lighter than old twist drill pipe45%), the footage is fast, the dust is small, the vertical downward drilling does not leave rock debris, and the hole is cleared. The rod body can be used separately from the drill tail to extend the service life. Spring pin or threaded connection, convenient and fast. This product is divided into single spiral blade, compound spiral blade and water type and dry type, especially suitable for high-density mine water exploration and gas drilling. In the mine high-density water exploration and gas discharge drilling or other special environment operations, it is necessary to determine the reasonable drilling depth according to the actual material physical properties and parameters of the drill pipe.
4. 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.
