Knapp’s patented single-piece, bi-directional scraping pipeline pig. The K-Disc is unmatched for paraffin scraping ability.
To insure unparalleled quality, the patented and proven K-Disc is manufactured exclusively by Knapp Polly Pig in Houston, Texas, USA and Monterrey, Mexico.
The Knapp K-Disc Pig has no metal parts which could damage the pipewall or costly pipeline ancillary equipment like pumps and compressors. The solid, one-piece polyurethane elastomer construction prevents the pig from coming apart
in the line.
Tough line-sized scraping discs located at each end of the pig remove stubborn deposits while the over-sized central discs provide the flexible seal necessary to propel the K-Disc through the pipeline.
The K-Disc’s patented design allows the pig to seal and scrape equally regardless of the direction it is moving in the pipeline.
The K-Disc pig was designed to be used as an on-stream maintenance tool capable of being propelled by the produced media whether it is a gas or a liquid.
The K-Disc pig is available in many different formulations of Ultrathane, Knapp’s exclusive Ultra Performance Urethane, which are fine-tuned for the job requirements. Ultrathane’s superior elastomeric physicals characteristics in tear and tensile strength provide the ultimate in long wear and scraping ability.
