Coal drill pipe is a tool accessory for mining consumables, a high-efficiency twist-shaped drill pipe used in coal seam drilling auger drilling rigs, generally made of high-quality carbon steel, suitable for use in coal electric drill drilling.
There are two types of coal drill pipes: solid (dry coal drill pipe) and hollow (wet coal drill pipe). They have diameters of Φ26, Φ28, Φ30, Φ38, Φ40, etc. According to the needs of drilling and production, the length is generally 0.5- 6M. , The product buckle type uses spring pin or threaded connection. Coal drill pipes are used in conjunction with various pneumatic anti-outburst drilling rigs, using spiral drilling technology, which has the characteristics of fast drilling speed, good drilling shape, and high drilling efficiency. Compared with the traditional drilling speed, it is much faster. The impact of drilling construction on the excavation progress during coal seam excavation is minimized, and it is widely used in coal mines, gypsum mines and other drilling and mining.
The use of special materials improves the willfulness and strength, hardness and wear resistance of the drill rod.
The dry-type electric coal drill pipe is made of high-quality steel, which has been specially processed to improve the strength, hardness and wear resistance of the drill pipe. The service life is prolonged and the economic benefit is improved.
The new type of dry-water dual-purpose drill pipe is made of special materials on the basis of coal drill pipe, which improves the toughness, strength, hardness and wear resistance of the drill pipe, and extends the service life. It is 3-5 of coal drill pipe. Times. Features: light weight, fast water flow, large-pitch powder discharge, high efficiency, and reduce labor intensity of workers. (Pitch and connection method can be customized according to user needs)
