When mining drill pipe is in use, the most common concern is the occurrence of fracture. What causes drill pipe to break during mining?
We have analyzed the reasons for the fracture of mining drill pipe in the process of use. There are mainly the following factors.
1. The drill pipe welding is not in place, the welding is not thorough
This is mainly related to welding level and welding process control. Through the field welding process tracking, it is found that in the welding process, the operator uses the ordinary electrode, and the width of the weld and the way of welding are not specific requirements, in order to improve the efficiency, the operator uses the thick electrode only welding, which reduces the strength of the welding, not through the situation, and the bottom is not fused to the welding.
2. There are cracks in the weld
The main reason is that the mechanical and physical properties of welding rod and drill pipe body material difference is large, resulting in cracks in the weld.
In the process of using drill pipe in coal mine, there will be a variety of breakage and damage, which may be caused by the quality of drill pipe itself, or the mine terrain. Among them, improving the product quality of drill pipe is our fundamental method to prevent mine accidents. Our company provides mining drill pipe products with guaranteed quality.
