Tapered drill bits play an important role in rock drilling and exploration projects in today's society, but they also need to be maintained in time after use, otherwise, they can be easily damaged. Today we will talk about the maintenance methods of threaded drill pipes.
What are the maintenance methods for threaded drill pipes?
1、Drill pipe should be maintained regularly, with maintenance cycle time specified, and rust and ash removed on time.
2、The application of the drill pipe needs to be within the rated drilling distance of the drilling rig, and the matching drill pipe should be selected according to the basic parameters, models, and specifications of the drilling distance.
3、When working in hard rock formations, coal rocks, or other special natural environments, the drilling depth of the drill pipe should be determined according to the actual physical property index of the material and the main parameters of the drill pipe.
4、When the drill pipe is used together with the drill bit, the drill bit should generally exceed the radius of the drill pipe. Pay attention to the condition of the drilling rig and drill pipe at all times during the whole drilling process. In case of emergency blockage, stop drilling immediately or return to drilling slowly to ensure that the drill pipe is not bent and deformed.
5、When the gouge drill pipe is naturally ventilated or supplied with water, the drill pipe should be connected firmly when drilling. When the drill pipe has sealing materials such as O-rings, attention should be paid to the application of sealing materials. In case of sudden damage, corrosion, etc., seal materials should be replaced immediately. Clean and maintain the sealing materials after successful drilling.
6. When drilling the drill pipe, it should be manually operated and slightly tightened to ensure a tight fit (threaded type). Direct drilling with the drill rig is not allowed to avoid damage to the drill pipe.
7、If the curvature of the drill pipe exceeds the standard requirements or the thread is damaged after use, resulting in the top hammer drill pipe cannot being constructed normally, it should be scrapped or returned to the factory for repair immediately.
8、According to the standard, the drilling depth of the drill pipe should be guaranteed to meet the relevant regulations to avoid the problem of the drill pipe falling off due to the drilling depth reaching the use limit of the rock drilling pipe.
9、When working in acid and alkaline areas, pay attention to the corrosive effect on the drill pipe. After successful drilling, wash the surface of the rod with water immediately to remove the corrosive layer.
10、Drill pipes need to be stored in a dry place with a little more support at the bottom. When stored for a long time, the drill pipe of the top hammer drill should be cleaned and maintained in time.
11、Drill pipe shall not be used as a supporting platform for stacking heavy objects. Drill pipes shall not be placed under gravel or coal piles or scattered places.
12、After cleaning, maintaining, and descaling the threaded drill pipe, the protective cap must be tightened or stored in the cabinet to ensure that the drill pipe is always new
