About Us

Of the many pigs we offer, our line of foam pigs, with sizes ranging from 2″ to 48″, are available in standard designs of bare swabs, criss-cross, wirebrush, silicon carbide, plastic bristle, and total-wire designs. Our foam mixing and pouring machines allow us to offer light, medium, and heavy densities, as well as, special densities for unique applications. Our abrasive series of foam pigs for cleaning applications, include standard carbon steel wire, stainless steel wire, silicon carbide (in loose grit or bonded strap), and plastic bristle for internally coated lines and various plastic pipe types (PVC, fiberglass, HDPE).

Our line of solid-cast pigs include cup-type, disc-type, combination cup-and-disc type, as well as, modular pigs with all individual components of the pig being manufactured from polyurethane. All styles of our utility solid-cast pigs are able to accommodate brushes for cleaning applications and transmitters for tracking applications.

As for steel-mandrel pigs, we manufacture sizes ranging from 2″ to 48″ nominal pipe diameters with configurations including, but not limited to, two-cup, four-cup, two-disc, four-disc, conical-cup, multi-disc, articulated pigs, and pigs with wire brushes or paraffin-removal blades. These pigs can also be equipped with gauging plates, magnets for ferrous debris pickup, and transmitter cavities. We also offer special designs for unique applications.

Complementing our line of steel pigs, Pigs Unlimited International, Inc. is the only full-line pig manufacturer that builds replacement pig brushes in-house. These include carbon steel, stainless steel, and prostran for internally coated lines and plastic pipes. Various design types are wire-wheel, circular-hub, wrap-around, and spring-loaded. Replacement brushes can be manufactured for use with our steel pigs or for other manufacturer's pigs.

As a standard, our field-proven cups, discs and other polyurethane spare components are manufactured to an 80 Shore A durometer. However, varying durometers can be supplied for other specific customer applications. In addition to our standard polyurethane, other compounds for spare-component construction include neoprene, epdm, buna-n, hypalon, and viton for extreme high-temperature and low-temperature applications, or for special chemical-resistant requirements.

Besides our standard line of pipeline pigs, we also have the capacity and willingness to manufacture specialized products under contract where required by client companies. We appreciate the opportunity to offer our services and look forward to the challenge. Some of these include special pig designs where either private labeling is desired or special designs for applications requiring a new design style of pig. Additionally, we offer pigging-related products, such as launchers, receivers, pig trackers, pig detectors, closures and pigging valves, as well as, other products directly related to pigging operations. As for our customers, they span all types of industries all over the globe. In these names, you will see end-users, distributors, service companies, intelligent pigging companies and even competition — for we manufacture pigs and/or components for which they do not. The following is a small sampling of the companies, location, and type of industries we have served. We look forward to adding you to our list of satisfied clients.
