  • Patent number: 4738145
    Abstract: The torque imposed on premium thread connections between tubular goods is monitored and plotted as a function of time rather than the number of turns. In this manner, the torque at which "shoulder", either by metal-to-metal sealing contact or otherwise, is achieved during make-up of the premium connection can be detected. Further, torque response of the connection after shoulder may be monitored. In addition, torque conditions during back out or disconnection may be monitored. Data obtained indicate if connections and seals are acceptable or not and often furnish evidence of the reason for certain types of unsatisfactory connections.
