The rib drill pipe and groove drill pipe produced by our company belong to the category of geological spiral drill pipe,Rib drill pipe, groove drill pipe in the use of the way and working environment are different, we focus on the geological spiral.Drill pipe, rib drill pipe, groove drill pipe three kinds of drill pipe specifications, their own characteristics and the scope of use of three aspectsconduct research.
3.1. Specification and application scope of geological spiral drill pipe
3.1.1 Specifications and models of geological spiral drill pipe: Φ34mm, Φ42mm, Φ50mm, Φ60mm, Φ63.5mm,The outer diameter of drill pipe formed by winding spiral blades with Φ73mm and Φ89mm specifications as inner pipe diameter belongs to geological spiralSpecification and model of drill pipe.
3.1.2, geological spiral drill pipe is mainly suitable for medium-hard geological conditions above the deep hole drilling construction, geological screw.The rotary drill pipe greatly improves the production efficiency of drilling construction, and is the first choice for efficient drilling construction, energy saving and consumption reduction in coal mines.Products.
Specification and application scope of 3.2 and rib drill pipe
3.2.1 Specification and model of rib drill pipe: Φ50mm-42mm, Φ63.5mm-50mm, Φ73mm-63.5mm,Φ89mm-73mm 、 Φ98mm-73mm 。
3.2.2, the rib drill pipe is based on the geological drill pipe, the use of high wear-resistant plane spiral blades, after pre-response.Force winding and fully automatic welding. The drill pipe body is made of high-quality alloy steel pipe for geological drilling, and the drill pipe is connected.The head is made of 42CRMOA high-quality alloy structural steel, which is first formed by high-pressure forming, vacuum tempering treatment, friction welding, etc.into the production process of production and processing.
3.2.3, this series of products in the drilling construction slag discharge speed, rotation resistance is small, at the same time with the geological drillingThe high strength performance of the rod and good slag discharge effect, due to the large lead and planar structure design of the spiral blade,Therefore, the phenomenon of drill pipe locking and drilling tool damage and loss is greatly reduced under the soft coal seam and the impact of the ground pressure strip. AnotherIn addition, due to the wide spiral blade of the rib drill rod, the rib drill rod will not cut the drill hole during the drilling construction.The hole wall will not cause the deflection of the hole wall and affect the drilling effect.
Specification and application scope of 3.3 and grooved drill pipe
3.3.1, groove drill pipe is also called body rib drill pipe, specifications and models mainly include: Φ50mm, Φ63.5mm,Φ73mm, of which Φ63.5mm and Φ73mm models are more common. The grooved drill pipe is made of thick-walled pipe as the pipe body,Milling grooves are processed on the pipe body. At present, we mainly produce one groove, two grooves and three grooves.
3.3.2. The application scope of grooved drill pipe is basically the same as that of rib drill pipe, which is mainly applied to soft coal seamFor deep hole drilling, compared with the rib drill pipe, the groove drill pipe has fast slag discharge speed and rotation speed.The advantage of low resistance and the advantage of the integrated design process and its wall thickness when drilling deep holes,Its wear resistance is better and its service life is longer.
