Maximize efficiency and tackle complex drilling challenges with our HDD Dual Wall Drill Pipe (Dual Rod). Engineered for advanced horizontal directional drilling, this system integrates a high-strength outer drill pipe with an inner casing or rod, allowing for simultaneous drilling and casing operations or efficient dual-fluid circulation. Designed for compatibility with leading rig brands like Drillto, Vermeer, Ditch Witch, and XCMG, and fully customizable, it is the ultimate solution for projects demanding speed, stability, and versatility in unstable soils, utility bores, or environmental drilling.
The HDD Dual Wall (Dual Rod) system revolutionizes standard drilling by performing two critical functions in one pass. The robust outer rod transmits torque and thrust, while the inner rod facilitates efficient spoil removal via air/fluid circulation or acts as a temporary casing. This design significantly recreases drilling time, enhances borehole stability, and minimizes fluid loss in unconsolidated formations, offering a faster return to grade and lower total project cost.
Simultaneous Drill & Case: Install temporary or permanent casing while drilling, perfect for unstable top soils, sand, or gravel beds. Saves time and eliminates separate casing runs.
Superior Borehole Integrity: The outer pipe stabilizes the borehole in real-time, reducing risk of collapse and ensuring accurate pilot hole alignment for product pipe pullback.
Efficient Spoil Removal: The annular space between the dual walls allows for optimized drilling fluid or air flow, improving cutting transport and reducing the risk of stuck pipe.
Adaptable & Customizable: Available in a range of standard diameters and lengths. We offer full customization of outer/inner diameters, thread types (e.g., API, proprietary), and lengths to match your specific rig (Drillto, Vermeer, etc.) and project geology.
Rugged Construction: Manufactured from high-grade steel, with precision-machined, wear-resistant connections to handle high torque and tensile loads.
Product Type: HDD Dual Wall Drill Pipe / Dual Rod System
