1. New Custom Material
The newly developed drill pipe material, created in partnership with professional manufacturers, possesses high tensile strength and excellent impact toughness. Its incorporation greatly enhances the load-bearing capacity of the drill pipe and effectively extends its service life.
2. Professional Thread Structure
The drill pipe thread for Raise Boring Machines adheres to the DI-22 international standard, characterized by a large helix angle and a coarse thread profile. This design effectively prevents issues such as wire burning and pipe breakage, resulting in higher reliability.
3. Thread Surface Hardening Treatment
Depending on the working conditions, the thread surface can be selectively treated with nitriding to increase surface hardness and prevent thread seizing.
