Trenchless Pipeline construction projects
Drill pipe plays a key role in trenchless pipeline construction, especially horizontal directional drilling (HDD), which installs pipelines underground without extensive trenching. A rig first drills a pilot hole, which is then enlarged so the pipeline can be pulled through. The drill pipe carries the drilling fluid that cools and lubricates the bit, removes cuttings and keeps the borehole stable.
HDD drill pipe must be made of high-strength steel, with tool joints and coatings designed for efficient fluid flow and structural integrity. Compared with trenching, HDD reduces environmental disruption and surface restoration, and allows pipelines to be installed in difficult terrain or congested areas.
Command Tubular can manufacture drill strings up to 7 5/8” in diameter for challenging HDD pipeline projects.
