Product Description
The non-grooved double-wall drill rod is composed of an inner drill rod and an outer drill rod (called inner drill rod and outer drill rod).
The inner cavity hole of the inner drill pipe is a channel for pumping water or mud to the construction hole during operation.
In engineering operations, the outer drill rods are connected to each other by threads, and the inner drill rods are connected by male and female joints of internal and external hexagonal structures.
When the inner and outer drill rods are driven by the time-sharing power output, they rotate independently and transmit torque by shifting.
