HDD Drilling Rod
  • Describtion
  • Size Available
  • Quality Control
Trenchless Technology or we may call it NO-Dig is developed rapidly these 20 years. Geotec Wuxi started HDD industry since 2008, and we are specialized in manufacturing forged one-piece and friction welding drill rod and our rod can be compatible for both of chinese and oversea drill machines and all terrain machines.We have build a long-term and stable raw material supplier which is also our authorised supplier.

We understand QUALITY is much more important than QUANTITY. So all the manufacture processes are checked and controlled by ourselves, such as raw material check, end-upsetting, quenching,shot blasting and package.In order to track and review our processes, we record laser mark on each pipe,for a better after sales survey.

Eco-friendly drill pipe is our principal issue to support environemnt. Our dark silver color of drill pipe is our unique color and present our mission.
