摘要： A "dump" or bypass system for use with fluid-powered tongs utilized to apply torque forces to threaded connections during pipe installation operations employs a multi-stage dump valve assembly (100). A computer (300) having a data processor monitors and analyzes rotations of, and torque forces applied to, pipe sections being assembled. The dump valve assembly includes a pilot-operated relief valve that actuates a bypass dump valve. The bypass system operates in "real-time", quickly and efficiently dumping fluid supplying a power tong and stopping the application of torque forces on a pipe section once a predetermined measured torque value is achieved.
