BC Bi-Directional Cup Pig
Bi-directional cup pigs are manufactured with a steel or polyurethane body and symmetrical polyurethane sealing cups at both ends, allowing the pig to run in either flow direction. They are primarily used for pipeline cleaning and removal of loose debris. Additional applications include batching and product displacement, line dewatering, and operating in pipelines where flow reversal may occur or where the pig must be recovered from the launch end.
Optional configurations include different cup profiles and hardness grades, bypass ports, brush or magnet attachments, transmitter or pinger cavities, pulling eyes, and custom diameters or lengths to suit specific pigging requirements.
BD Bi-Directional Disc Pig
Bi-directional disc pigs are manufactured with a steel mandrel body and multiple polyurethane sealing and guiding discs arranged symmetrically along the body. They are commonly used for pipeline cleaning, batching, and product displacement. The disc arrangement provides stable sealing and good centering through bends, valves, and fittings in both forward and reverse runs.
Available options and configurations include sealing and guiding disc combinations, bypass ports, brush or scraper attachments, magnets, transmitter or pinger cavities, and custom diameters or lengths to suit specific pigging requirements.
