Drill pipes, as a part of OCTG(oil country tubular goods) are essential components in the drilling process for oil and gas exploration and extraction. They serve as conduits for drilling fluids, house the drilling bit, and provide a means for transmitting rotational torque and axial force to the drill bit. The application of drill pipes is primarily in the drilling of boreholes, including oil and gas wells, geothermal wells, and water wells.
