  • Device for pipeline interior cleaning
    Patent number: 6553602
    Abstract: The present invention relates to a pipeline interior surface cleaning device that is propelled through the pipeline by the operational properties of the transported medium. A speed regulator controls the rate of forward motion of the device and a series of off-axis wheels enables the device to travel in a spiraling motion through the pipeline. A series of sealing members, scraping elements, brushes and magnets loosen and collect particles on the interior pipeline surface as the cleaning device spirals through the pipeline.
