Fiberbuilt Composite Pigging Seals

  • How Does the Composite Pig Seal Work?
    • Seal Diaphragms are captured between rows of support brushes. The brushes provide support and shape for the seal, and support the pig inside the pipeline.


  • How is it different from a standard urethane pig seal?
    • The seal is made up of several parts: diaphragms provide the seal barrier, and brushes provide all of the support. The Seal assembly is very flexible and can flex to move around any inconsistencies in the inside geometry of the pipeline.


  • How is it low-drag, how much pressure is required to push it through my pipeline?
    • The flexibility of the seals, the low wall forces, and the steel on steel sliding contact all work to reduce the friction between the seals and the pipe wall. In small diameter applications (3-inch to 8-inch), the differential pressure has been estimated from field measurements at between 2-15 psi to move the pig through the pipeline depending on the pipeline flowing conditions, and level of debris encountered.


Batching, Dewatering and Light Utility Cleaning Pigs

  • How is this pig different from a urethane pig?
    • The seals are much more flexible and work across a wide range of pipe schedules. A typical seal can operate in pipe ID +/- 25% from the nominal size.  For applications requiring this size flexibility, contact the Fiberbuilt Engineering team to determine the best pig configuration for your pipeline concerns.


  • Does it last longer than a standard pig?
    • Field trials have shown that a Fiberbuilt Light Utility Cleaning Pig (Batching/Dewatering) will generally last as long as a standard Urethane type pig. This depends somewhat on the line conditions.


  • Does it clean better than a standard pig?
    • The Fiberbuilt Light Utility Cleaning Pig (Batching/Dewatering) has a flexible seal design that provides light wall cleaning. This pig should be deployed in light cleaning applications that require a flexible pig to traverse complex pipeline geometry.


Fiberbuilt Corrosion Pit Cleaning Brush

  • How does the brush work to clean corrosion pits?
    • The brush has a unique design that causes the brush fibers to penetrate into the bottom of any corrosion pits encountered in the pipe wall. The design, orientation, construction and materials have been optimized to effectively perform this pit cleaning.


  • Why does it work better than a regular brush?
    • Regular brushes use radial brush fibers with a limited oversize to the pipe ID. Radially oriented brush fibers will not effectively penetrate outwards into the corrosion pits.


  • What kind of measurements on the cleaning are available?
    • Fiberbuilt has performed many pipeline flow loop tests to quantitatively measure the ability of the corrosion put cleaning brush to remove debris and penetrate to the bottom of the corrosion pits. Please see the R&D/Presentations section to view some of these results or contact the engineering team at Fiberbuilt to discuss the corrosion pit cleaning brush performance.


  • Can I put Fiberbuilt Corrosion Pit Cleaning Brushes on my Pigs?
    • The Fiberbuilt Corrosion Pit Cleaning system has been designed to work as a complete system. IF you require a custom configuration for your pipeline pigging needs please contact the engineering team at Fiberbuilt.


  • How long does the Corrosion Pit Cleaning Brush last?
    • Field trials have shown that a Fiberbuilt Corrosion Pit Cleaning Pig will generally last as long as a standard Urethane type brush pig. This depends somewhat on the line conditions.


Fiberbuilt Cleaning and Scouring Brushes

  • Aren’t all Pipeline cleaning brushes the same? What’s different about Fiberbuilt Brushes?
    • Fiberbuilt uses advanced ILI style brush designs and construction methods to produce pipeline cleaning brushes that perform much better than existing pig brushes. The brush fiber materials and brush configurations are optimized for pipeline cleaning.  Fiberbuilt brushes are made from high strength steel wires that resist permanent deformation from the pipeline ensuring a consistent cleaning performance along the pigging run.


  • Can I put Fiberbuilt Brushes on my own Pig?
    • Fiberbuilt brushes are available in custom designs and configurations for mounting to any existing pig.  Contact the Fiberbuilt engineering team to discuss your custom application and get the right brush produced for the job.
