CSNRI Snap Wrap is a multi-layered system of high-strength, corrosion-resistant fiberglass that forms a composite split sleeve. Designed for repair and reinforcement in tight quarters, on pipe that is difficult to access, and on subsea pipe, it is installed with a high-performance adhesive and filler material and works best on pipe operating to <1,000 psi.

The split sleeves can be applied quickly and easily even in challenging environments, such as underwater, in splash zones, and on pipe racks with limited clearance, and require no cutting, welding, or special tools
