Abstract
An apparatus for making and/or breaking a threaded connection between a first tubular and a second tubular according to one or more aspects of the present disclosure may include a spinner operable to spin the first tubular relative to the second tubular; a zero-side-load (“ZSL”) device operable to relieve the transverse force induced on the threaded connection in response to the spinner spinning the first tubular; a torque wrench operable to rotate the first tubular relative to the second tubular; and a back-up wrench operable to grip the second tubular.
Claims28
An apparatus for making and/or breaking a threaded connection between a first tubular and a second tubular comprising:
- a spinner operable to spin the first tubular relative to the second tubular;
- a zero-side-load (“ZSL”) device operable to relieve the transverse force induced on the threaded connection in response to the spinner spinning the first tubular;
- a torque wrench operable to rotate the first tubular relative to the second tubular;
- and
- a back-up wrench operable to grip the second tubular.
The apparatus of claim 7, wherein the external frame is a cassette.
An apparatus for making and/or breaking threaded connections between a first and a second tubular comprising:
- a spinner operable to spin the first tubular relative to the second tubular;
- a torque wrench;
- a back-up wrench;
- and
- a torsion device connected with the torque wrench and the back-up wrench, wherein the torsion device is operable to relieve a transverse force induced in response to rotating the torque wrench relative to the back-up wrench.
A method for making-up a threaded connection between a first tubular and a second tubular, comprising:
- providing a tubular joining device comprising a spinner, a torque wrench and a back-up wrench;
- gripping the second tubular with the back-up tong;
- spinning the first tubular via the spinner to advance the pin relative to the box;
- gripping the first tubular with the torque wrench;
- rotating the first tubular with the torque wrench to complete the threaded connection;
- and
- relieving a transverse force induced on the threaded connection in response to spinning the first tubular.
