‌High-Toughness Triangular Spiral Groove Center Cable-Through Drill Pipe‌

‌High-Toughness Triangular Spiral Groove Center Cable-Through Drill Pipe‌

‌Product Description‌

The triangular spiral groove high-toughness center cable-through drill pipe is directly milled from the drill pipe body. The spiral grooves primarily reduce resistance during pipe advancement/retraction. When encountering jamming or burial incidents requiring rotational pulling, the groove edges crush trapped coal blocks while utilizing the grooves for cuttings removal, effectively addressing drilling obstruction phenomena.

‌Product Features‌

Integrated structure enhances torsional strength and bending resistance.

Excellent sealing ensures stable signal transmission under 12 MPa pressure.

Constructed with Baosteel specialty steel, delivering high strength and impact toughness.

Large-pitch trapezoidal thread design improves transmission efficiency and root strength.

Triangular spiral groove structure effectively agitates borehole walls for rapid coal debris discharge.

‌

Applications‌

Primarily used for:

Directional long-hole drilling in underground coal mines

Water exploration/drainage boreholes

Near-horizontal directional engineering drilling in surface/tunnel environments.
