ABSTRACT:
A pressurized fluid line servicing tool assembly consists of a tool insertion adaptor, a cap removal tool and a plug setting tool. The tool insertion adaptor connects to a pipe of a pressurized fluid line and enables tools to be inserted and removed without releasing pressurized fluids, such as natural gas, to atmosphere. It has a tool insertion chamber which is divided into an upstream portion and a downstream portion by a valve. The cap removal tool connects to the tool insertion adaptor to enable service personnel to pass a cap removal wrench through the valve to remove a cap from an end of the pipe of the pressurized fluid line. The plug setting tool connects to the tool insertion adaptor to enable service personnel to pass a torque settable plug through the valve to set a plug into the end of the pipe.
