Knapp Pipeline Cleaners

摘要

Knapp Polly Pig founded in the 1950's by Mary Knapp, is a recognized leader in the manufacturing of all types of pipeline utility pigs. Knapp is the original manufacturer of the Polly Pig, the urethane foam-bodied internal pipeline cleaner that is used daily by pipeline operators throughout the world to maintain the flow efficiency of their lines.rnOver the years, the original foam pigs have evolved along with a number of innovative cast elastomer pigs, and metal mandrel pigs to a point where Knapp has held over 50 patents, both U.S. and foreign.
