Technology of double wall drill pipe
The double wall drill pipe is mainly made of special alloy steel pipe. The joint of the drill pipe is made of alloy structural steel through friction welding, vacuum quenching and tempering treatment, and overall surface hardening. The thread processing adopts automatic processing equipment, which has the characteristics of high bending strength, reliable welding, and high slag removal efficiency. Compared with the similar products, the fatigue strength is improved.
