摘要： The thread engagement verifier system provides for verifying the quality of a threaded connection 12 between upper and lower for tubular member 16, 18. One or more thermal radiation sensors 14 are used in combination with a data acquisition and processing computer 20 and an output device, such as a video display 12. The thermal radiation is generated by sliding friction between the tubular members, and the sensors 14 sense radiation at a plurality of external locations and output heat intensity signals to the computer 20. Torque may also be sensed via a sensor 32 and input to the computer 20.

摘要： A tong assembly having a powered tong mounted over a backup tong is supported at its rear by a post with torque measuring means. The powered tong is supported at its front, near its throat, by one or more struts that extend downwardly to the backup tong. Such strut (s) provide support for the powered tong when the assembly is placed on a support surface for storage. The struts each have a joint with a retracted condition in which the joint is rigid when the tong is placed on a support surface, and an extended condition in which the joint allows a degree of lateral displacement when the tong assembly is applying torque to a pipe string. This maximizes the amount of torque passing through the rearward post, and therefore ensures a more accurate sensing of applied torque by the torque-measuring device.

摘要： A tongs monitor for monitoring the tightening of tubing, casings, and sucker rods of a well is selectively operable in a learning mode and a monitoring mode. A target tightness value is determined during the learning mode. Subsequent tightness values are then compared to the target value. For example, a first connection is tightened in a conventional manner, while its tightness is monitored during the learning mode. If the tightening process went well, then an operator pushes a button that tells the monitor to remember how tight the first connection was tightened. The tightness value of that first joint then becomes the target tightness value for any subsequent joints. As additional joints are tightened, their tightness are monitored and compared to the first one to ensure that all the joints are as good as the first one within an allowable tolerance.

The apparatus may include a positioning apparatus for determining the position of the tubular relative to the tong. The positioning apparatus comprising a plunger movably disposed on a base and coupled to a visual indicator. The plunger includes a contact member disposed at one end, whereby contact with the tubular causes the plunger to move along the base and the distance traveled is indicated by the visual indicator. The apparatus may further include a torque measuring flange. The flange comprising a top plate and a bottom plate. The flange further includes one or more cylinders disposed between one or more wedges, whereby rotating the top plate causes the wedges to compress a piston in the cylinder. In another aspect, a positioning tool may be mounted on a lower portion of the tong. The positioning tool includes a centering member for determining a position of the tubular and a positioning member for engaging the tubular. The positioning tool further includes means for actuating the centering member. The position of the tubular may be actively adjusted by actuating the centering member.

The system is also preferably provided with a backup tong. The sides of the power tong are preferably provided with rollers to prevent friction between the power tong and the guide. In a second power tong system, a load cell assembly is provided in which a load cell is linked by a series of links to the power tong such that movement by the power tong in either of two transverse directions loads the load cell. In a third power tong system, an improved backup tong is provided in which jaws, preferably symmetrically disposed on the backup tong and each carrying dies, are moved about pivots by a rigid link between the jaws and a linear actuator. The dies are preferably provided with more than one die seat for locating the dies at different positions on the jaws. A third die may be provided, preferably symmetrically arranged with the dies on the jaws. The third die may be located on the linear actuator.

摘要： A control system for power tongs comprises two tongs torque limiters, one of which limits tongs torque to a very low (hand-tight) level; the other limits torque at full makeup to, for example, 2000 ft. lb. The hand-tight torque limiter is manually or automatically disabled after the hand-tight level is reached. The system enables the operator to verify that the threads are properly engaged before applying full torque to the connection. The tongs have a very high reduction ratio, so that torque rises very slowly and can be more accurately controlled.
