Conductor torquing system |
摘要 |
A conductor torquing system is provided for large diameter threaded conductor casing which comprises a lower chain vise adapted to grip a first joint of conductor casing, a plurality of movable arms operable to apply a retaining force to a second joint of conductor casing to maintain the latter in rotational contact with a spinning means. The spinning means is operable to rotationally make-up the second joint of conductor casing to the first joint of conductor casing to an initial make-up torque value. The apparatus also includes an upper chain vise for gripping the second joint of conductor casing and applying a final make-up torque to the threaded connection. The apparatus will allow a conductor connection to be made-up in a safe and efficient manner and generally assist in reaching the final torque stage more rapidly.
