Bi-Directional PIPeLINE 

 Cleaning Pigs

Various sizes and configurations available

Enduro’s Bi-Directional Cleaning Pigs are versatile, steel-bodied pigs most commonly used as fill and displacement pigs during hydrostatic testing, but they can also be run in unidirectional service when required. Built for flexibility, these tools support multiple cleaning and batching configurations and are available in a broad size range to suit a wide variety of pipelines

Key Features


  • Steel-Bodied Design – Available in sizes 2"–60", with replaceable components in 4-disc or 6-disc configurations.
  • Fill & Displacement Ready – Ideal for use as fill and displacement pigs during hydrostatic testing, while remaining fully capable in cleaning and batching applications.
  • Configurable Cleaning Options – Optional gauging plates, magnetics, and wrap-around brushes (3" and up) can be added to tailor the pig to your cleaning objectives.
  • Tracking Compatible – Enduro transmitters can be installed in sizes 4" and larger (special body available for smaller sizes), enabling reliable pig tracking.
  • Pipeline Tolerance – Designed to traverse pipe reductions of up to 25%, helping maintain pig passage and performance in lines with diameter changes.

FAQs

  • What’s the primary use of Bi-Directional Cleaning Pigs

    They are most often used as fill and displacement pigs during hydrostatic testing, but they can also be used in unidirectional cleaning and batching runs.

  • Can Bi-Directional pigs be configured for more aggressive cleaning?

    Yes. Optional wrap-around brushes, magnets, and gauging plates can be added to enhance cleaning performance, especially in lines with debris or scale. 

  • Are these pigs transmitter-compatible?

    Steel-bodied versions can be fitted with Enduro transmitters in sizes 4" and up, and UreFlex versions in sizes 6" and up, allowing you to use your tracking receivers and geophones for pig location.
