V-Wrap™ Carbon Fiber System

V-Wrap™ Carbon Fiber is a structural strengthening system for the restoration or renewal of pressure pipe. The system has been tested and meets or exceeds durability requirements necessary to provide the desired service life for pipeline structures.

V-Wrap™ Carbon Fiber (CFRP) systems are comprised of high-strength carbon fibers fully saturated in a resin matrix. These thin, low-profile laminates are bonded to the interior or exterior of pipelines forming a composite lining with the existing host pipe structure.

Applied both longitudinally and circumferentially, the V-Wrap™ system is layered to meet specific design requirements. Working with STRUCTURAL TECHNOLOGIES, owners and consultants receive comprehensive design and technical support from project start to implementation in the field.

Features:
  • V-Wrap layers in pipeApplicable internally for pipe diameters 30” (760 mm) and above. For diameters below 30” (760 mm), please contact STRUCTURAL TECHNOLOGIES.
  • NSF-61 approved
  • Low profile system typically 1/2-inch to 1-inch - maximizes pipe diameter and reduces flow loss
  • Corrosion resistance creates long operational life
  • Rapid installation process
  • Custom designed to provide up to full structural capacity including internal pressure and external loads
  • Fits straight and curved pipe sections
  • Withstands high design pressure
Functions:

V-Wrap CFRP

  • Restores full functional capacity of pressure pipelines
  • Can be used to increase the structural capacity of an existing pipe allowing increased pressure and flow rate
  • Increases bending capacity and strength of the pipe
Benefits:
  • No excavation or shafts required to perform internal repairs
  • Excellent for localized repairs
  • Minimal downtime and impact to operations
  • Polymer coating improves flow
