Pigs Unlimited International, Inc.
Pigs Unlimited Inc., with its over 50 years combined in pig manufacturing, manufactures a full-line of pipeline pigs for internally cleaning pipes in the water industry.
Pigs have been used in cleaning pipes for over 30 years. With the basic design originally being that of a "plug", they have now evolved to being fairly sophisticated pipeline cleaning devices. Ranging in standard sizes from 2" to 48," they can be manufactured in varying densities, lengths, diameters, styles and configurations (including swab, criss-cross, and abrasive) to best suit the application. They are capable of negotiating short-radius bends, valves, tees, and multi-dimensional piping.
