Bidirectional Pigs are used for a wide range of applications, from flood, clean and gauging operations to dewatering, as well as operational maintenance.

ARR pig configurations can be modified to run dual-diameter and multi-diameter pipelines as well as through features such as Wyes, Unbarred Tees, and Check Valves. Typically built with four sealing discs and two guiding discs, this can be enhanced to provide greater sealing, increased wear life, or even hold backpressure. ARR has a reputation for reliability and expertise in pig design for difficult pipelines.
