114mm 4.5'' Stainless Steel Wear Resistant RC Drill Pipe with Reverse Circulation Mechanism for Mining

RC Reverse Circulation (RC) Drill Pipe is a specialized drilling component used in mineral exploration, geotechnical drilling, and water well construction. It enables efficient reverse circulation drilling, a method where cuttings are brought to the surface inside the drill pipe rather than through the annulus, ensuring faster and cleaner sample recovery.

1.Reverse Circulation Mechanism

Cuttings travel up through the inner tube of the drill pipe, while drilling fluid (air or water) is pumped down the annulus between the inner and outer pipes.

Provides high-quality, uncontaminated samples for accurate geological analysis.

2.Dual-Wall (Double-Wall) Design

Outer Pipe: Provides structural strength and stability.

Inner Pipe: Smooth-bore tube for efficient cuttings transport.

Annulus Gap: Allows pressurized fluid to reach the bit.

3.High-Strength Materials

Made from high-grade alloy steel for durability in harsh drilling conditions.

Often wear-resistant to extend service life.

4.Threaded Connections

Precision threads (e.g., Metzke or Remet) ensure strong, leak-proof joints.

5.Compatibility with RC Hammers

Works with RC drilling hammers that use compressed air to drive the bit and lift cuttings.

Product Advantages

Faster Penetration Rates – Efficient cuttings removal reduces downtime.
Superior Sample Quality – Minimizes contamination compared to conventional drilling.
Reduced Fluid Loss – Ideal for dry or fractured formations.
Versatile Applications – Used in mining, water wells, geothermal, and geotechnical projects.
