Friction welded drill pipe, also known as geological drill pipe and conventional drill pipe in coal mine tunnels, is mainly produced and processed by advanced friction welding technology. The drill pipe has the characteristics of high bending strength and firm welding. The production equipment is fully equipped with advanced numerical control processing equipment, which can ensure the straightness requirements during deep hole drilling, and has high fatigue resistance and long service life.
Friction welded drill pipes are mainly used in drilling, mining and anchoring in coal mines, mines, construction and water conservancy projects, railways, highways, bridges and tunnels. In coal mines, it is mainly used for water exploration, gas exploration, and roadway exploration in coal mines.
