Geological drill pipe classification and purchase skills Drill pipe consumer manufacturers bring you the classification of geological drill pipes and the purchase of geological drill pipes. According to different classification methods, geological drill pipes can be divided into: high-efficiency geological drill pipe, triangular geological drill pipe, geological geological drill pipe, wide-blade geological drill pipe, cfg geological drill pipe and long geological drill pipe. 1. High-efficiency geological drill pipe: the drill pipe body is made of high-pressure seamless alloy steel pipe, and the spiral blade is made of high wear-resistant T-shaped steel strip, which is prestressed and wound and welded. The drill pipe joint is made of high quality medium carbon diamond by vacuum conditioning and high pressure forming. This series of products using a four-way or six-way fast convergence mode, transport.
Geological Drill Pipe Classification and Selection Skills
Drill pipe consumer manufacturers bring you the classification of geological drill pipes and the purchase of geological drill pipes. According to different classification methods, geological drill pipes can be divided into: high-efficiency geological drill pipe, triangular geological drill pipe, geological geological drill pipe, wide-blade geological drill pipe, cfg geological drill pipe and long geological drill pipe.
1. Efficient geological drill pipe:
The drill pipe body is made of high-pressure seamless alloy steel pipe, and the spiral blade is made of high wear-resistant T-shaped steel strip, which is prestressed and wound and welded. The drill pipe joint is made of high quality medium carbon diamond by vacuum conditioning and high pressure forming. This series of products adopts a four-way or six-way fast connection mode, which is automatically locked by a spring pin when used, and is equipped with a U-shaped or semi-ring anti-release pin to make the torque of the drill pipe reach the best state.
2. General geological drill pipe:
Geological drill pipe is in the geological drill pipe high torque performance of the root, the use of single spiral blade or double spiral blade, through the prestressed winding process processing and welding. It is used in coal mine and drilling engineering, especially suitable for deep hole drilling of soft coal seam and similar coal seam with poor water and slag discharge effect. Geological drill pipe provides guarantee for efficient deep hole drilling in mine and fills the domestic blank. The geological drill pipe has the characteristics of high fatigue strength and high shear strength.
3. Long geological drill pipe:
According to the different drilling pressure methods used in drilling, the drill pipe is divided into three types: friction pressure type drill pipe, machine lock pressure type drill pipe and combination pressure type drill pipe. Friction type drill pipe common due to the soft formation of drilling construction, can be drilled into the silt layer, soil, sediment and pebble layer. The long geological drill pipe has the characteristics of fast drilling speed, good drilling forming, high drilling efficiency, greater torque, stable operation, automatic locking of spring pins, and quick disassembly. When drilling deep holes, the drill pipe is also equipped with a gear pin, which increases the transmission torque and greatly reduces the loss of the drill pipe. And the use of plug-in thread connection, easy to quickly disassemble, good sealing, high tensile strength, into the pile of high quality characteristics. Good verticality, easy to disassemble and device.
Choose high-quality drilling pipe, please identify the beneficial mining drilling tools.
