Geological auger drilling pipe with high torque and fast deslagging speed
Based on the production technology of our geographical drill stem and high torque performance, Geographical suger stem with single-screw blade. is processed by means of prestress winding and full automatic welding technology. The product , applying top-quality special geographical alloy steel pipe as its drill rod and top-quality alloy steel as its joint with vacuum quenching and tempering treatment, has higher fatigue resistance and shearing strength.
The drill stem has the merits of high bending strength, firm welds, and etc. With advanced production equipments and professional technical team. our products have been made with high production efficiency reliable quality, wining high praise from our customers of the industry. The products can meet the demand of the straightness of deep-hole drilling, with the merits of high torque, fast deslagging speed, well-formed hole, and no drill pipe sticking, especially suitable for the deep drilling of soft coal seam or similar rock. As for the drilling of super soft and high pressure coal seam, in the sleeve drilling construction, φ98, φ113, φ133, φ146 geographical auger stem can be chosen to set the core barrel conveniently. The series of products guarantee the high-efficiency deep hole drilling, filling in the blank of the industry in our country.
OEM is accepted.
