High Performance HDD Drilling Tools , No Dig Drill Pipe Friction Welding
Description:
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.
Advantage:
A: Ablity
From 2009,we provide OEM service for Vermeer China,now we also have cooperation with Ditch Witch Asia Agent. We also have relationship with many China main HDD manufactures.
B: Quality
