Rotary drill pipes
Rotary drill pipes are included in a complete drill string and made by joining a pin end tool joint, a mid-body tube and box end tool. Different grades of raw material are used so the pipes are well suited to a variety of rock hardness and abrasiveness.
Features
Productive performance
Drill pipes prevent most operational drill string part failures through quality collaring, desk bushing and rod support. By matching the drill string tool componentry needs to your specific drill rig, you can achieve a balance between stability for column strength and optimum bit/drill string performance.
Premium quality
The drill pipes efficiently handle hard rock and abrasive formations in surface mines, quarries and construction, due to efficient engineering and high-quality components. Each component is optimized for application, which allows extreme torsional and axial loads to be transmitted through the rotary drill string.
Safety
All Roschen sandvik drill string tools have weight stamped on the component. Given the weight involved, use lifting aids when handling drill string tools.
