SYSTEMS AND METHODS FOR SWAB TRANSPORT IN PIPELINE REHABILITATION

摘要

A method for transporting a swab through a pipeline, or through an insert within a pipeline, according to the present invention may include coupling a swab launcher to the pipeline, the swab launcher having a launch chamber with a first inner diameter large enough to receive a swab when the swab is substantially uncompressed and a narrowing portion configured to compress the swab to fit within the pipeline, inserting the swab into the launch chamber, pressurizing the launch chamber with a compressed fluid behind the swab, and advancing the swab with the compressed fluid through the narrowing portion and into the pipeline.
