Abstract
A wrench and method of using the wrench to properly make up threaded connections is provided. The wrench includes at least a strain gauge coupled thereto, such that when the wrench is used to turn one part of a threaded connection, the strain associated with different states of the making up of the connection is monitored, to establish a baseline condition after which the one part of the threaded connection is turned an additional number of degrees, turns, or fractions of a turn. The wrench and method may be used to make up fluid tight connections, where previously the threaded parts were finger tightened, followed by turning thereof an additional number of degrees, turns, or fractions of a turn.
