CSNRI Atlas Wrap

Description

CSNRI Atlas Wrap Permanent Carbon Fiber Composite Repair for Pipelines

CSNRI Atlas Wrap is the most tested carbon fiber composite solution for the permanent repair and rehabilitation of pipelines and piping structures. Engineered to permanently restore original pipeline strength, CSNRI Atlas Wrap is designed to address both common and complex pipeline anomalies while maintaining strict compliance with international codes and regulatory standards .

The Atlas system utilizes high-strength carbon fiber fabric saturated with advanced epoxy resin to create a structural composite repair that reinforces pipelines without welding or cutting. The system includes Atlas UA, a unidirectional fabric engineered for axial reinforcement while installing in the hoop direction, improving installation quality and structural performance compared to traditional composite alternatives.

Product Benefits

• Permanent Structural Repair – Restores pipeline integrity and original strength
• No Hot Work Required – Safer alternative to welding
• Minimal Operational Disruption – Install without shutting down pipeline operations
• Flexible Composite System – Conforms to complex deformations and low-clearance areas
• Cost-Effective Field Installation – Reduces labor and equipment requirements
• Reduced Repair Length vs. Steel Sleeves – Installs over non-injurious hard spots and laminations
• High Strength Carbon Fiber System – Circumferential tensile strength of 166.7 ksi
• High Glass Transition Temperature (216°F / 102°C)

Engineering Performance Data

• Circumferential Tensile Strength: 166.7 ksi (1.15 GPa)
• Circumferential Tensile Modulus: 9.81 Msi (67.6 GPa)
• Axial Tensile Strength: 19.9 ksi
• Ply Thickness: 0.017” (0.43 mm)
• Glass Transition Temperature: 216°F (102°C)
• Max Recommended Application Temperature: 140°F (60°C)
• Shelf Life: 24 months

These properties confirm CSNRI Atlas Wrap as a high-performance carbon fiber composite repair system engineered for demanding pipeline environments .

Typical Applications

CSNRI Atlas Wrap is ideal for permanently restoring serviceability to pipelines experiencing:

• External corrosion and pitting
• Dents, gouges, and scratchesWeld defects and manufacturing flaws
• Wrinkle bends and deformations
• Cracks (conditional cases)

It is suitable for transmission pipelines, process piping, and piping structures transporting oil, gas, chemicals, water, and steam.
