Friction Welded Drill Rods Of Various Specifications Are Used For Well Digging Machines
Rock Drill Rods Characteristics
Integral drill rods are ideal in small hole drilling, all integral drill rods consist of hex. rods with integrated cemented carbide chisel-shaped bit heads. With the same steels as and the best carbides made in China, we are supplying different lengths of integral drill rods with different head diameters:

Rock Drill Rods Brief Introduction
Integral drill steels / rods are used by a hand held drill machine in underground mining and for small hole drilling, equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc. It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 30mm to 41mm usually. Regarding Integral drill steels,the quality of a steel material and a tungsten carbide is very important to get good drilling performance.
manufacturing process
Thickening of steel pipe: Firstly, through the process of thickening the steel pipe, the outer surface of the smooth pipe is bent inward, and the wall of the steel pipe is thickened to improve the strength and wear resistance of the drill pipe.
Thread processing: Thread processing is performed on thickened steel pipes and coated with copper that can increase strength, improving the fatigue resistance and connection strength of the threads.
Welding treatment: Welding of steel pipe body joints, followed by welding heat treatment and final welding treatment of the pipe body to eliminate welding residual stress.
Quality inspection: Before painting and packaging the finished drill pipe, various tests should be conducted on the steel pipe product, including hardness testing, pressure testing, and non-destructive testing, to ensure that the quality and performance of the drill pipe meet the requirements.
