How Flange Isolation Kits Work

How Flange Isolation Kits Work

Flange isolation kits are designed to prevent electrical conductivity between flanged pipe connections, helping control corrosion and improve the effectiveness of cathodic protection systems. At Flange ISO, our isolation solutions (EVOLUTION®, LineBacker™, Pikotek®) are engineered for demanding pipeline environments where long-term reliability, sealing performance, and corrosion protection are essential.

A flange isolation kit typically includes an isolating gasket, insulating sleeves, and insulating washers. When installed between two flanged pipe sections, these components create a complete electrical barrier that prevents stray currents from passing through the connection. This isolation helps reduce galvanic corrosion and ensures cathodic protection systems function as intended across the pipeline network.

By interrupting the electrical path, flange isolation kits help maintain system integrity in oil and gas pipelines, water and wastewater systems, chemical processing facilities, and other industrial applications where corrosion control is critical.

Flange ISO kits are commonly used across various Industries to extend asset life, reduce maintenance costs, and improve pipeline reliability. When properly specified and installed, they play a key role in comprehensive corrosion management strategies.
