Product Description:
Double-arm drill pipe is also called double-layer drill pipe. It consists of inner and outer drill pipes (called inner pipe and outer pipe). The inner and outer pipes form an annulus, which is a channel for pumping the flushing medium to the bottom of the hole during hydraulic rock drilling and center sampling drilling. The central hole of the inner tube is used to discharge the flushing medium and is integrally fixed, and the threaded button of the outer tube is connected between each double-wall drill pipe to ensure the transmission of torque and pressure.

Advantage
This series of reverse circulation pipes can increase the permeability of the lost stratum, reduce the consumption of drilling fluid, protect the reservoir stratum, and save the cost of other consumable tools. In addition, the pipeline can be drilled in two directions to control the drilling. The reverse circulation kill method can transfer heavy mud directly to the bottom of the well without periodic circulation, saving time.
