Product details

The drill rod of a core drill rig is a very important part of drilling engineering, mainly used to transmit drilling power (such as rotation and impact) to the drill bit, and bring the drilled core samples back to the surface. Drill rods are usually made of high-strength steel pipes to withstand working environments with high pressure, high temperature, and high torque.

The drill rod of a core drilling rig mainly has the following characteristics:

1. Material selection: In order to ensure the stability and durability of the drill pipe in harsh environments, high-strength alloy steel or other high-performance materials are usually used for manufacturing.

2. * * Structural design * *: The drill rod is hollow inside to facilitate the extraction of core samples; There is usually a spiral groove design on the outside, which helps with the circulation of coolant or flushing fluid, improves drilling efficiency, and protects drilling tools.

3. * * Connection method * *: Drill rods are connected through specific threads or quick couplings to ensure good sealing and stability even under high pressure and high torque conditions.

4. * * Length and diameter * *: Depending on different drilling requirements, drill rods will have different length and diameter specifications to accommodate drilling requirements at different depths and diameters.
