ABSTRACT:
An improved cleaning pig with selectable debris flushing action for use in a pipeline to be moved through the pipeline by the flow of fluid therethrough, the pig being formed of a cylindrical body of semi-rigid material having shallow depth channels formed in paralleled spirals on the cylindrical surface, the spirals extending less than the full length of the body leaving an uninterrupted portion of the cylindrical surface, and an elongated, brush member positioned in each of the channels, each of the brush members having bristles which extend generally radially outward from the pig body, the width of the brush members being less than the width of the channels providing fluid flow passageways within each of the channels whereby segments of said uninterrupted cylindrical portion of the body may be cut away to establish communication of the flow passageways with both ends of the body to permit fluid to flow past the pig as it is moved through a pipeline to thereby flush debris which has been brushed from the pipeline sidewall forwardly of the pig so that the debris will be carried out of the pipeline, the amount of fluid flow past the pig being selectable by the width and depth of the uninterrupted cylindrical portion which has been cut away.
