Description

CSNRI SnapWrap

Composite Split Sleeve System for Non-Welding Pipe Repair

CSNRI SnapWrap is a multi-layered, high-strength fiberglass composite split sleeve designed for fast, non-welding pipeline repair and reinforcement. Engineered for challenging environments, CSNRI SnapWrap provides structural reinforcement and corrosion protection for pipe operating up to < 1,000 psi.

This advanced composite sleeve system is internally coated with a high-performance adhesive and filler material that bonds directly to the parent pipe, forming a durable structural repair. Designed specifically for tight access areas, subsea environments, splash zones, and congested pipe racks, CSNRI SnapWrap eliminates the need for cutting, welding, or special installation tools.

Available in diameters ranging from ¾ inch to 56 inches, CSNRI SnapWrap can be quickly installed in onshore, offshore, and underwater environments making it one of the most versatile non-welded pipe repair systems available today.

Product Benefits

• No Hot Work Required – Eliminates cutting and welding for safer on-stream repairs
• Minimizes Unplanned Downtime – Fast installation reduces production interruptions
• Designed for Tight Access Areas – Ideal for congested pipe racks and difficult-to-reach piping
• Subsea & Splash Zone Capable – Lightweight system easily installed by divers
• Corrosion-Resistant Composite Construction – High-strength fiberglass provides long-term durability
• Extends Asset Life – Reinforces aging and corroding pipelines
• Prevents Future External Corrosion – Composite barrier protects from environmental exposure
• No Environmental Hazards – Clean installation process without sparks or emissions
