V-Wrap™ Carbon Fiber Pipe Strengthening System
V-Wrap™ Carbon Fiber is a structural strengthening system for the restoration and renewal of concrete, metallic and polymer-based pipelines. The system has been tested and meets or exceeds durability requirements (ICC-ES) 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 2-part 100% solids epoxy 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.
- Fully structural repair system – custom designed to address all internal pressure and external loads
- Low profile system (typically 3/8-inch to 1-inch)
- Long term lifecycle extension of pipeline assets
- Segmental repairs or extended reaches of pipe, fits straight and curved pipe sections (virtually any pipe geometry)
- Restores full functional capacity of distressed, degraded or damaged pipelines
- Upgrade the structural capacity of an existing pipe allowing increased operating pressure
- Maintains water tightness of pipe under changing conditions of original pipe
- NSF 61 and Annex G certified for drinking water pipelines
- ICC-ES approved – meeting or exceeding industry standards for long-term durability
- No excavation needed – access through standard manholes
- Minimal downtime and impact to operations
