Brush cleaning pigs are used during pre-commission and on-stream pipeline cleaning where rust, mill scale, sand, wax, organic growth, mud, oxides, and other foreign matter exist
Brushes are added to pipeline pigs for aggressive cleaning of the internal diameter of pipelines. They come in a variety of configurations; from a rotary brush – a full circle mounted as one piece on a urethane pig – to wrap brushes, to spring-loaded brushes mounted to a Super Pig or steel mandrel body pig. Brushes can be made from flat wire for more aggressive cleaning of tenacious deposits, or fine wire for more flexibility or corrosion pits.
Our Brush Cleaning Pigs are highly efficient and are based on a bi-directional pig design, being fitted with polyurethane guide and seal discs. The guide discs support and centralise the pig as well as providing a cleaning action on the internal pipewall to loosen and push most medium to hard deposits in front of the pig. The sealing discs maintain a tight seal within the pipeline to provide the pig with the drive to traverse the line.
