Drill Pipe for Water Well Drilling Rig
- Drill Rod Diameter: 34-60mm
- Length:500-3000m/piece
- Production process:Friction welding/Threading of ontology
- Connection form:Lash connection/Joint connection
Features
- 1The drill rod body is made of high quality geological special alloy steel pipe, and the drill rod joint is made of high quality alloy structural steel. After vacuum quenching and tempering treatment, the fatigue strength and shear strength are largely improved.
- 2Adopting advanced friction welding technology, the drill pipe has the characteristics of high bending strength and strong welding.
- 3The production equipment completely adopts advanced CNC processing equipment, high production efficiency, high quality and stability.
- 4It can guarantee the straightness requirements in deep hole drilling. This product has high fatigue strength and long service life.
- 5According to the actual needs of users, we can design and produce various special specifications and performance drilling tools.
