| Abstract | A pipeline pig suitable for use in cleaning deposits and buildup from an interior surface in a pipeline is also particularly suited for applications wherein the pipeline has a series of bends, right angles or even plug headers. The pig is suitable for bidirectional travel, having front and rear hemispherical noses. The pig is constructed in a manner that facilitates a greater degree of elongation and deformation than is possible with known pipeline pigs, while still providing the radially outward bias that is required to effectively scrape the sidewalls of the pipeline. A cover carries a plurality of metal studs arrayed about the cylindrical middle portion, and encloses an internal core. The core is formed in a mold from a mixture of resin and ISO, resulting in a pig having superior ability to elongate and deform, if needed, while still effectively scraping the sidewalls of the pipeline. |
