With their unique design, both dual-diameter and multi-diameter pigs are capable of negotiating varying diameter piping configurations that other pigs cannot. Available in sizes of 3″ x 4″ and larger, they can also be equipped with brushes for cleaning operations.

Note: As with all special pigging applications such as dual-diameter or multi-diameter projects, it is best to discuss in more detail the characteristics of the pipe to determine the best-suited pig and/or pigging method.
