Features of HDD Drill Rods:
1). Double-step structure is used for its male and female threads,
so this kind of drill rod has optimal sealing property and after
torsion, there is little transformation in the rod.
2). Pipe end upsetting technology, self connecting mode and heat
treatment have been used in the manufacture of this kind of HDD
drill rod. Thus, our drill rods in different specifications possess
excellent mechanical properties.
3). Our HDD drill rods can work together with various horizontal
directional drill rigs within and beyond China.
4). Chemical plating (electroless plating) is used on the surfaces
of threads so as to improve the hardness of surface and abrasive
resistance of thread.
