Drill pipe manufacturers: how to maintain the trolley drill pipe

1. It is necessary to carry out regular maintenance on the drill pipe of the trolley, determine the maintenance cycle, and carry out regular anti-rust and dust-proof treatment.
2. When using trolley drill pipe, it is necessary to select the corresponding drill pipe within the rated drilling distance of the drilling rig and according to the technical parameter model of the drilling distance. The drill rod is made by friction welding of special geological drilling pipe fittings for mining geology and its matching joints. It has good follow-up and tensile strength, and can be used for conventional drilling and gas venting. When operating in hard rock, coal seams or other special environments, the drilling depth must be determined according to the physical properties and parameters of the actual material of the drill pipe.
3. When the trolley drill tool is used in conjunction with the drill bit, the diameter of the drill bit is generally larger than the diameter of the drill tool. During the drilling process, always pay attention to the condition of the drill rig and the drill pipe. In the event of sticking or violent death, stop drilling immediately or return to drilling at a slow speed to ensure that the drill pipe will not bend or flatten.
4. When the drill pipe of the trolley is ventilated and watered, it must be ensured that the drill pipe is closely connected to the ground. When geological drill pipes have sealing rings, such as O-rings, attention should be paid to the use of the sealing rings. Once they are damaged or corroded, they should be replaced in time. After drilling, the seal is maintained and cleaned.
5. When the trolley drills the drilling tool, it should be manually tightened gently to ensure a tight fit (thread type). The drilling tool cannot be directly drilled to avoid damage to the drilling tool.
6, if the bending degree of the trolley drilling tool exceeds the standard requirement after use, or the thread is damaged, etc., it cannot work normally, it should be scrapped or repaired in time.
7. In accordance with the requirements of the standard, ensure the drilling depth of the drill pipe of the rig to meet the relevant requirements of geological drilling, and prevent the phenomenon of falling off due to the use of the drill pipe at the drilling depth.
8. When working in an acid-alkali environment, attention should be paid to the corrosion of the drill pipe. After drilling, clean water should be used to remove the corrosion layer on the surface of the drill pipe in time.
9. Trolley drill pipes should be stored in a dry place, and the bottom should be supported at multiple points. The drill pipes should be regularly maintained during long-term storage.
10. Trolley drill pipe cannot be used as a heavy tail support platform, nor can the drill pipe be placed under gravel, coal or scattered randomly.
11. After repairing and removing rust/dust of the drill pipe of the trolley, the protective cover or the box should be buckled to ensure that the drill pipe is frequently used and new.
