Foam Disc Pig

This foam disc pig offers pipeline operators the scraping ability of a disc pig and the flexibility of a foam pig. The disc's multiple scraping surfaces provide wiping power in a pig that can be inserted into the system without the necessity of an expensive launcher. The pig is available in a variety of foam densities and coatings.

The disc removes condensate from gas flowlines, water after hydrotesting, scale in water piping, grease from force mains, and paraffin from oil flowlines. The pig can be run in either direction within the pipeline. It has no additional pieces that can come apart in the line. It is ideally suited for use in pipelines with varying wall thickness.
