Abstract
A method of and apparatus for making up two members having mating threaded connections, such as pipe joints or bolts, for insuring that a specified number of threads have been engaged and a specific torque has been applied. The mating threaded connections are threadably engaged while measurements are made of the torque required to turn one of the members relative to the other, and measurements are made of the number of turns of the members relative to each other. In order to insure that a bad joint is not made up, the measurements of torque and turns must remain within specified parameters or the threaded interconnection is discontinued. The method and apparatus further includes avoiding erroneous turn measurements that may occur such as due to bending or swaying of one of the members during makeup.
