SLD NC-1 Automatic Torque Control System is a highly reliable torque signal processing, control, and recording system. It enables precise measurement, real-time display, data logging, and intelligent control of torque during pipe make-up (threading), ensuring that pipe joints achieve the optimal make-up torque value. The system provides full-process monitoring and data retention for the tightening of each joint, with graphical records (e.g., torque curves) generated during the process stored on a disk for future query and analysis.
The system can be used together with power tong and bucking unit, keeping the torque within the range required by AMERICAN PETROLEUM INSTITUE (API standard). It intends to protect tubing from damaging tubes when torque is out of the range.
