Raw material
1. Internal and external upset forging
2. A highly specialized heat treatment process
3. Precision machined pin & box connections
The final stage of the manufacturing process for our drill rods is a rigorous quality control inspection process. We manufacture the highest quality drill pipe that technology will allow.
Friction Welded Drill Pipe
Friction welded drill pipe is made from three separate pieces that include the mid-body tube and two threaded connections or tool joints. The interim weld process is a solid-state welding technique that forges metal together without causing a melt to occur. Because there is no melt product produced during the inertia weld, there is no recast metal or grain enlargement after the weld is completed.
The Best Horizontal Drill Rod
Forged and friction Welded drill rod. Internal & External (IEU) Forged Drill Pipe
Our IEU integral forged or forged drill pipe is made up solely from one piece of material. The pipe has the same chemical makeup for the threaded joints and the mid-body tube with no weld zone between them.
