Abstract: An improved method of making up a pressure sealing threaded connection for oilfield country tubular goods is provided. A threaded connection is of the non-shouldered type, and includes a pin member having an external tapered thread and a box member having an internal tapered thread. The actual pitch diameter of the pin thread and the box thread are measured and preferably recorded on the outer cylindrical surface of each respective member. An indicator is positioned on the pin member at a preselected location with respect to the pin face end surface. The pin member and box member are made up to form the threaded connection, while the position of the box face end surface is monitored. Make-up of the connection is terminated in response to this position and as a function of the recorded deviations on the pin and box members.
