High Strength Φ69/Φ75 Drilling Rod For Mining Drilling Gas Water Drill
Core drilling rod introduction
The water-producing drill pipe generally refers to a round steel drill pipe, and a high-efficiency spiral drill
pipe. The water-producing drill pipe is made of high-quality steel, wear-resistant and pressure-resistant,
and has good long-lasting performance. A good water-producing drill pipe plays a very important role in
completing the drilling work. Great role..
Characteristics
1. Light weight (45% lighter than the old drill pipe).
2, the footage is fast, the dust is small, and the plumb holes are drilled without leaving cuttings and clear holes.
3, card bean connection is convenient and fast, saving strapping materials.
4. The separation between the rod body and the drill tail can be used upside down to extend the service life.
5, good water permeability during wet operation
