A system for accurately determining the torque applied to threadable pipe members, the system applied in connection with a pair of threadable pipe members, such as oilfield tubular goods, to be threaded together, a torque wrench (24) having a first end secured to the end of one of the pipe members, and a second end forming an extendable handle portion (32), a pulling means (26), such as a cable secured to the handle portion (32) for pulling the handle (30) in the direction to impart rotational force on the pipe members to complete the connection, means (38) intermediate the end of the handle (32) and the pulling means (26), for recording the torque being applied to the pipe member by the torque wrench (24) in all instances as a 90 degree relationship between the torque wrench (24) and the cable member (26), and means (36) for visually recording the force being applied to the threadable members (12). |
