Flange insulation kits that are fire-safe are a sealing bundle for flange connections and provide fire safety by preventing electric conductivity or isolating possible galvanic corrosion in pipeline systems. Engineered for high-temperature resistance and made from robust, flame-resistant architectural materials to meet industry requirements, these kits are recommended for oil and gas, petrochemical, and related industrial applications to provide an additional safety margin and a long life for the systems.
