Application of Forged & Friction Welding HDD Drill Rod:
HDD drill rod makes up the string that pushes and steers the bore on horizontal directional drilling jobs, from utility crossings under roadways to installations through congested urban areas.
Features of Forged & Friction Welding HDD Drill Rod
– Manufactured as forged one-piece or friction-welded construction.
– S135-grade steel, quenched and heat-treated.
– No paint finish on the rod body.
– Compatible with Vermeer, Ditch Witch, Case, and Chinese drilling rig thread standards.
More Introduction of Forged & Friction Welding HDD Drill Rod
Forged one-piece rod and friction-welded rod trade off differently on cost and repairability — forged rod is a single continuous piece, while friction-welded rod joins a separate tool joint to the tube, which can make joint replacement more practical if that’s the part that wears first.
