Abstract
A modular pipeline pig provides scraping cup having holes therethrough, adapted to retain a plurality of scraper studs. Positioned a well-defined distance behind the scraping cup is a driving cup defined by a slightly larger diameter than the scraping cup. The studs in the scraping cup may be of any appropriate shape or material, depending in the particular job. The driving cup is preferably mounted on the forward end of a mandrel, and another driving cup mounted to the back end of the mandrel. The pig is modular, so that other scrapers and or cups may be mounted to suit the needs of a particular job.
