Triangular cone drill pipe for coal mine roadway drilling, referred to as triangular drill pipe, triangular drill pipe, anti-collapse drill pipe, anti-lock drill pipe, etc. It is a drill pipe for coal mine drilling made by friction welding with a triangular arc steel pipe with tapered transition as the drill pipe body and a drill pipe joint in the form of thread or triangular, square, hexagonal and other connection forms. The material of the triangular drill is geological drill pipe. The triangular drill pipe body is made of high-quality geological alloy special steel pipe, and the drill pipe joint is made of high-quality medium-carbon alloy structural steel, which is formed by high-pressure treatment and friction welding. The performance advantages of the three-pronged drill pipe in the drilling process, the drill pipe.

Material geological drill pipe quality of triangular drill
The triangular drill pipe body is made of high-quality geological alloy special steel pipe, and the drill pipe joint is made of high-quality medium-carbon alloy structural steel, which is formed by high-pressure treatment and friction welding.
Performance advantages of triangular drill pipe
During the drilling process of the triangular drill pipe, three semicircular spaces are formed between the drill pipe and the borehole wall, which expands the channel for removing dust and gas, so that gas and pulverized coal can be discharged smoothly. When the drill pipe is rotated and drilled, the triangular edge of the drill pipe continuously greasy the excess drilling slag to the hole wall to solidify the hole wall. It greatly reduces the occurrence of the phenomenon of drilling tool locking and drilling tool damage caused by hole collapse in soft coal seam. This product has the characteristics of reasonable design, safety and reliability, good slag discharge effect, deep drilling depth and good drilling pipe effect. This product has become the preferred type of deep hole drilling in soft geological conditions and soft coal seam.
Use of geological drill pipe for coal mine
Drill pipe is a steel pipe with a threaded tail, which is used to connect the surface equipment of the drilling rig and the carbonylation at the bottom of the boreholeDrillor bottom hole device. The purpose of the drill pipe is to use the drill bit to transport drilling mud, and to raise and lower the diamond drill bit or rotary drilling device with the drill bit. The drill must be able to be subjected to pressure, torsion, bending and vibration in and out of the world. In the process of oil and gas extraction and refining, drill pipe can be used many times.
Mine pipes and round steel pipes are made of drill pipes after many processing stages. First, through the treatment of the steel pipe thickening process, the appearance of the light pipe is bent toward the inside, and the steel pipe wall is thickened. Next, the PDC drill bit is threaded and plated with copper to improve strength. Then a non-destructive quality management inspection is performed, followed by the steel pipe body joint welding. Then the welding joint residual pressure is eliminated by welding heat treatment and welding final treatment. Before painting and packaging the finished drill pipe, other tests such as hardness test, pressure test and non-destructive test must be carried out on the finished steel pipe.
