Pigs Unlimited International, LLC. is proud to say that since our inception, all of our pigs have been manufactured in the USA, and that has not changed. From our one location in Tomball, TX we can manufacture all styles of pigs and are able to service a worldwide customer base

Since their conception, pigs have been cleaning pipelines in the oil and gas industry for well over one hundred years. Now, pigs have branched into other industries, such as municipalities, power plants, mining, refineries, chemical plants, pulp and paper mills, food and beverage, and cosmetic and pharmaceutical. Also, over the years pigs have evolved from basic “plugs” to being fairly sophisticated pipeline cleaning devices. Standard sizes range from 2″ to 48” (but larger sizes can easily be designed and manufactured), and they can be manufactured in varying lengths, diameters, styles and configurations to best suit the customer’s application.
