Bi-directional Disc Pigs

Designed to be used for the displacement of water or air during hydrostatic testing of a pipeline IK’s range of Bi-directional disc/scraper pigs offer excellent high sealing qualities.

The range is comprehensive 2” through to 60”, with a variety of body constructions available. In sizes 2” up to 14” a spindle (bolt) body can be offered or alternatively the complete range up to 60” can be supplied as a multi bolt design.

The standard model is supplied with six polyurethane discs: two support/guide discs which assist loading and centralization in the pipeline and four sealing discs which drive, seal and scrape.

The scraping action of the sealing discs has proved successful in removing light deposits from the pipe wall; this cleaning ability can be further enhanced by the addition of brushes, plough blades or pin wheel discs. Other design options include the attachment of magnets (for debris collection), gauge plates and transmitter housings.

Extra sealing and guide discs can be added if the pig is to be used over long distance (150km) or the pipeline conditions are particularly arduous.

All IK’s pigs are supplied with polyurethane bumper noses as standard.
All IK’s pigs are designed to pass minimum 1.5D radius bends and negotiate full bore branches.
All multi bolt pig body assemblies are welded to code standard BS EN ISO 15614-1:2004+A1:2008. NDT testing (MPI) of the welds can be performed if requested.
