Introduction
HDD drill pipe is a kind of hollow and thick-walled steel piping (HDD: Horizontal Directional Drilling). As a kind of trenchless tool, it is often used on drilling rigs and horizontal drilling to facilitate the drilling of a wellbore and comes in a variety of sizes. The drill rod is hollow to allow drilling fluid to be pumped through it. Wuxi Geotec Geological Equipment Company mainly supplies friction welding drill pipes. In addition to this type of trenchless equipment, we also provide drill collar, saver sub, drill bits, pulling swivel, hoisting plug, cutter head and drill reamer.
HDD Drill Pipe
Established in 1980s, Wuxi Geotec Geological Equipment Co., Ltd. specializes in producing drill rods, diamond drill bits, core barrels, drill rigs, and other drilling tools. Through more than 20 years’ production experience and marketing experience, we have gained the recognition of a large number of clients both home and abroad. Our trenchless drill pipes have been widely exported to America, United Kingdom, France, Canada, Australia, New Zealand, Indonesia, India, Russia, Malaysia, Thailand, Mongolia, Pakistan, etc. If you have interest in our drill rods, please feel free to contact us.
