Contour Apex is a custom-engineered and optimized composite system for high-pressure pipeline repairs. It employs the proprietary Apex, optimized, bi-directional fiberglass in conjunction with a specially formulated and toughened epoxy system to address external corrosion and mechanical damage such as dents, wrinkle bends, and gouges on distribution and transmission lines.

Light-weight, corrosion-resistant Contour Apex makes maintenance easier, helping to prevent leaks and corrosion that lead to shutdowns. Repairs are fast, restoring line integrity and making the pipe stronger than it was before it went into service.

Contour Apex is compliant with ASME PCC-2 Article 4, and ISO 24817, and like all CSNRI products, it has been rigorously tested to ensure repeatable, reliable performance with durability for decades.
