Abstract: A pipeline pig has a body with two symmetrical, flexible end portions which give the pig a generally ovate appearance. The end portions are separated by and contain a flexible core. The end portions have a rounded exterior surface and an internal cylindrical cavity. Each cavity has a beveled entry portion for receiving the core. Each end portion also has an outer cleaning area for an abrasive band with teeth for scrubbing a pipeline. Polishing teeth are on an upper portion of the band while coarse teeth are on a lower portion of the band. The core allows the pig to flex as it passes through nonlinear pipeline. The core has a flexible linkage which gives the pig the ability to undergo extensive flexing while maintaining the integrity and strength of the pig. Each end of the linkage receives a bolt which extends through an axial hole in each end portion for fastening the end portions to the core. As the pig moves through pipeline with light build-up, the polishing teeth gently remove it.
