ABSTRACT:
A threaded connection assembly comprises a nut, a multiplier connected to the nut via a first threaded interface having a first number of threads per inch and a well servicing pipe coupling connected to the multiplier via a second threaded interface having a second number of threads per inch. A method of forming a threaded connection for a well servicing application comprises forming a pipe coupling between two well servicing pipe sections and threading a connector to the pipe coupling to form a threaded connection without impact loading the connector. Another method for forming a threaded connection comprises disposing a first pipe section partially within a nut, threading a multiplier into the nut, threading the multiplier onto a second pipe section, and leveraging the multiplier against the nut, or vice versa.
