Water Well Drill Pipe

Short Description:

Our self-developed perforated drill pipe improves drilling efficiency and drilling speed by reducing water pressure loss. The inner diameter of the upsetting end of the tool joint is basically the same as the inner diameter of the drill pipe body, and the pressure loss is reduced by 20%-50%. Flushing the internal structure reduces corrosion and improves fatigue resistance, enabling continuous sampling and wire rope drilling.
