Steel pigs can be manufactured in nearly any configuration, provided pipeline constraints are considered. Cups, discs, and brushes can be assembled in various combinations. Sealing and scraping discs can be combined with conical cups, scraper cups, brushes, and magnets to meet specific needs. Pigs Unlimited offers in-house custom manufacturing. Have a design idea? We can help build it. Need a custom urethane mold, special bolt holes, or unique attachments? We can help with those, too. Our experienced team can guide you through the design considerations and help solve challenging pipeline problems. Transmitters on steel pigs are usually mounted with a flange, although drop-in designs are available on some smaller models. Please consult us to determine the best option.
