Pencil Brush Cleaning Pig
Pencil Brush Cleaning Pigs are heavy duty, aggressive cleaning pigs equipped with a steel body, spring steel wire brushes and polyurethane bumpers and discs.
The Pencil Brush Cleaning Pig is offered in three standard configurations and available in sizes 6-inch and larger. The 5D-1BR will traverse a 1.5 DR bend while the 4D-2BR and 4D-2BR PitBoss™ will traverse 3 DR or larger bends. Special configurations are available to meet virtually any customer specification.
Both the Pencil and PitBoss™ brushes (in the case of the 4D-2BR PitBoss™ Pencil Brush Pig) are very effective at removal of black powder and cleaning deposits from internal pits.
All Pencil Brush Pigs are equipped with removable bypass plugs, which provide a jetting action to improve cleaning effectiveness.
This pig is rugged and easy to maintain. The brushes and discs provide excellent support to the pig, increasing the life of the discs.
All brushes and scraper discs provide 100 percent circumferential cleaning. Brushes are designed to conform to the inside diameter of pipe, thus ensuring effective cleaning of the pipe wall. The pigs are equipped with nonmetallic bumpers to protect the bolts and prevent metal-to-metal contact during pigging operations.
