Abstract
The invention relates to a method and apparatus for continuously monitoring the making-up a joint between two mutually-engageable threaded members (12,13,14,22,23), the threaded members having co-operating shoulder seal elements (18,19,20,21). The invention involves the application of torque to the mutually-engaging members and detecting when a shoulder-engaging position has been reached. A predetermined additional torque is then applied if a good joint is indicated as being achievable. If a good joint is indicated as not being achievable, the application of additional torque is terminated.
