摘要
A method for sensing and launching pipeline pigs into a pipeline. The method includes pressurizing a pressure accumulator in a pig launching system that includes a pig chamber, a plurality of pigs, a launch tube, and the pressure accumulator. The method further includes sensing a pressure within the pipeline and applying pressure from the pressure accumulator to force a pig through the launch tube and into the pipeline.
