Advantages of non-magnetic drill pipe-Yikuang Technology
Non-magnetic drill pipe is mainly used in horizontal directional drilling system of coal mine tunnel. Compared with non-magnetic drill pipe made of beryllium copper, special alloy non-magnetic drill pipe has the following advantages: (1) non-magnetic: it has non-magnetic characteristics, its magnetic permeability is 1.00005-1.0001 H/m under the condition of 20 Oster, and it will not be magnetized in strong magnetic field; (2) Low density: density 4.5 × 103kg/m3, 98% lower than the density of beryllium copper; (3) Low elastic modulus: the elastic modulus of beryllium copper is 1.35 × 105MPa, while the elastic modulus of this alloy is 1.17 × 105MPa, for which beryllium copper

Under the non-magnetic drill pipe-beneficial mining technology.
Non-magnetic drill pipe is the supporting equipment of directional drilling measurement while drilling, which has the functions of reducing the outside interference to the measuring device while drilling, signal transmission, conveying the power medium of the bottom motor of the hole and the power transmission of the drilling machine. It is an important part of the directional drilling tool in the coal mine. It has the characteristics of low magnetic permeability, high tensile strength and good torsion resistance, and provides a non-magnetic environment for the in-hole measurement system without magnetic interference of drilling tool, the magnetic field at the probe is almost equal to the nearby geomagnetic field, so the geomagnetic direction of the borehole can be accurately distinguished to ensure the measurement accuracy of the measurement system.

Introduction to the five characteristics of the cable drill pipe reamer-Yikuang Technology
The five characteristics of the cable drill pipe reamer are introduced. The cable drill pipe reamer has the following characteristics: ① The cable reamer can stir up the cinder deposited in the hole to improve the slag discharge capacity of the drill pipe, and can also play a secondary cutting role to reduce the cinder and facilitate the slag discharge. ② When the cable drill pipe encounters caving and hole collapse, the cable reamer can ream and then discharge the cinder at the collapsed hole to avoid sticking and burying; ③ Ensure the normal transmission of signals in the drill pipe during the drilling process; ④ When the drill hole has a sharp turn, the hole with large curvature can be reamed to realize the smooth transition of the drilling trajectory and avoid sharp bends; ⑤ According to different formation conditions, the drill pipe and the reamer

The main role of the shell part of the cable drill pipe reamer-Yikuang Technology.
The main function of the shell part of the cable drill pipe reamer is to ensure the strength of the cable drill pipe. The shell adopts an integral structure, and the modulated high-quality alloy steel is selected. The male and female joints are respectively processed at both ends of the outer tube to improve the overall strength. The blade slot adopts a large-diameter arc transition to avoid the reduction of the mechanical performance of the shell due to stress concentration.
