IP.BD bidirectional pig
Réf. DIP-165
IP.BD bidirectional pig Ø2" to 48" with four polyurethane discs, for swabbing during hydrostatic testing (water filling and dewatering). Alternative to spheres.
IP.BD bidirectional pig: overview
The IP.BD bidirectional pig (Ø2" to 48") has four polyurethane discs, a polyurethane end-protection nose and a towing eye at each end to ease removal. The in-house polyurethane mouldings have exceptional physical properties and chemical resistance, with high wear resistance; the carbon steel body is coated with two layers of anti-corrosion paint. It passes through full-bore and direct-passage valves as well as barred tees: sizes 2"-6" negotiate bends from 3D, 8" and above from 1.5D.
In use, it provides bidirectional swabbing during pipeline hydrostatic testing, allowing both water-filling and dewatering operations. It is an alternative to spheres, which removes the need to fit sphere tees at branches.
