Solid cast urethane combination cup and disc scraping pipeline pig.
The ideal combination of scraping and sealing capabilities in one tough, long-lasting pipeline cleaner.
The Knapp Ultra-Cast Pig is a one-piece design with a sealing cup at the front and rear of the pig and two scraping discs between them.
A cup shape is the most effective design to allow a pig to run long distances yet maintain a good drive seal.
A disc shape is the most effective design to scrape foreign materials off pipe walls. Ultra-Cast discs are thicker at their base to keep the edge of the discs from bending too much.
The Knapp Ultra-Cast pipeline pig is available with circular, wrap-around steel brushes and various tracking options.
Knapp’s Ultrathane is a premium grade polyurethane elastomer custom formulated for specific job requirements.
