ABSTRACT:
A self-extracting service module for piping infrastructures comprises a platform on which is mounted equipment for controlling and or monitoring the flow of liquid or gaseous media throughout the piping infrastructures. A first remote-controllable pipe coupling system is interconnected with the equipment inlet and a second pipe coupling system is interconnected to the equipment outlet. The platform is attached to actuators positioned near each corner of the platform. The actuators cooperate with at least one pressure-driven device. The service module is extracted from the piping infrastructure by isolating the equipment from the flow of liquid media after which, the pipe coupling systems are remotely disengaged from the piping infrastructure inlet and outlet. The actuators are operated to move the platform from within the piping infrastructure to a position where service work is easily performed on the equipment without the attendant hazards and constrictions associated with confined spaces.
