Geological Exploration Drill Rods / Geological Drill Pipes
- Product Description
-
Applied to Geological exploration, Well Drilling, Geothermal well Drilling Engineering
There is Geological drill pipe /The drill collar is connected to the Kelly, transmitting the rotary table's torque to the bit at the bottom of the well while also serving as a conduit for circulating drilling fluid. The material used for the collar is selected— Shanghai Baosteel STM-R780 (42MnMo7) is resistant to fatigue, bending, or fracture, and delivers consistently stable and reliable performance. Rod The end undergoes intermediate-frequency heating, hydraulic upsetting for thickening, and then proceeds to… 12 Hours Burial-type tempering ensures the compactness of drill rods, Improve Mechanical properties. All Adopt Precision imported CNC lathes equipped with custom-molded cutting tools for threading operations, Precision also ensures a tight connection with the locking connector.
We Both is possible Production Different Materials, Length, diameter 、 Drill pipes with wall thickness can also be customized according to the customer’s specified material, length, and wall thickness. 、 Thread Come Custom drill rods.
