Solid cast urethane cup and disc fluid control pipeline pig.
The Ultra-Flex pipeline pig was designed with flexible urethane cups and discs so that can pass easily through pipeline joints, valves and bends.
Economical one-piece construction means no costly
spare parts to inventory or lose in the line
Lighter than conventional metal pigs, the Knapp Ultra-Flex does not sacrifice strength or endurance for the convenience of light weight.
The hollow body of the Ultra-Flex pipeline pig expands with line pressure to further improve the pig’s seal.
The Ultra-Flex pipeline pig is also available with an additional cup on the front of the pig to accommodate eccentric launchers. The Ultra-Flex can be ordered with handling strap and various trackiing options.
Knapp’s Ultrathane is a premium grade polyurethane elastomer custom formulated for specific job requirements.5
