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.

A pumping system comprising a motor, wherein the motor has an operating speed, a pump coupled to the motor, wherein the pump has a volumetric displacement, a fluid end coupled to the pump, wherein the fluid end is operable to draw fluid from an input and provide fluid to an output, and a control system operable to regulate the motor and the pump in order to provide fluid to the output at a selected pressure and flow rate within a continuous range of pressures and flow rates between the peak horsepower output and peak torque output of the motor.

An apparatus for rotating a threaded tightening device includes a guide and an anvil utilized to impact a lug on the threaded tightening device to rotate the tightening device onto or off of a threaded member. The guide has a frame with a support sleeve attached thereto. A reciprocating device is received in and is supported by the support sleeve. The anvil is attached to the reciprocating device. When the reciprocating device is received in and is supported by the support sleeve, actuation of the reciprocating device will cause the anvil to repeatedly impact a lug to rotate the threaded tightening device in the desired direction.
