SLIPPAGE SENSOR AND METHOD OF OPERATING AN INTEGRATED POWER TONG AND BACK-UP TONG
Method and apparatus to make-up or break-out a threaded tubular connection using an integrated power tong and back-up tong (10). The power tong (20) may be disabled upon sensing a predetermined threshold amount of displacement of at least a portion of a back-up tong (14). The sensed displacement ind...

description | Method and apparatus to make-up or break-out a threaded tubular connection using an integrated power tong and back-up tong (10). The power tong (20) may be disabled upon sensing a predetermined threshold amount of displacement of at least a portion of a back-up tong (14). The sensed displacement indicates that the back-up tong (14) is slipping, and power tong (20) rotation may be disabled to prevent damage to the pipe string (16) or surrounding equipment. A slippage sensor (40) may be disposed to sense displacement of at least a portion of the back-up tong (14) relative to a supporting frame (12). In one embodiment, the slippage sensor (40) may be operatively coupled to a valve (50) disposed in communication with a fluid line (46) supplying power fluid to the power tong (20). The power tong (20) may be disabled by impairing flow to the power tong (20) upon sensing a predetermined displacement of the back-up tong (14). |
