Tubular Joining Apparatus
First Claim
1. 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.

21. 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. - View Dependent Claims (22, 23, 24, 25, 26, 27, 29)
