Detailed Product Description

 

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

  1,The only one in China who do heat treatment for the whole body of the drill rod. Our special Design heat treatment line is highly valued by Vermeer in China.

  2,Excellent forging tech in China.

  3, Adopting double shoulder for improving mechanical property.

 

Features and advantages:

 

1.excellent comprehensive mechanical properties. 

2.wear resistant.

3.high fatigue strength and long fatigue life. 

4.good flushing effect to ensure high drilling rate.

5.widely application and accurate size.

6.origin of material: our materials are come from bao steel which is the best steel factory in China.
