Foam disc pigs have a series of ridges or discs that help to provide extra wiping and sealing capabilities. Because this foam pig provides such a good seal, foam disc pigs are ideal for a number of applications including, product recovery and removal, de-watering, and nitrogen purges. Foam disc pigs are available in both medium and heavy density urethane foam. Foam disc pigs can be modified to accommodate transmitters, magnets and/or radioactive sources. Foam disc pigs can also be outfitted with ropes or pull straps to make pig removal easier.
