Raise Boring Drill Rod with Advanced Friction Welding Technology
The drill pipe adopts equal strength design, which reduces the overall weight of the drill pipe and effectively improves the drilling depth capacity and the fatigue resistance of the drill pipe.
The design of equal strength constructions can reduce the local peak stress of drill pipes, and improves the anti-fatigue ability of the drill pipes. The weight is also less than common.
The steel used in the production of our drill rods is vitally important because rods must be able to withstand tremendous loads. Understanding that not all steels of a specific grade are produced to the same quality level and knowing the catastrophic effects of a drill string failure, we are committed to providing value to you through high-quality products demonstrating durability and strength.
