Flange Repair

Belzona flange repair systems reform damaged flange faces subjected to harsh chemicals, crevice corrosion, galvanic corrosion, and high-pressure steam.

Corrosive fluids, crevice corrosion, bimetallic corrosion, and steam can all result in deterioration and subsequent leaking of flanges. By utilizing a Belzona flange face repair solution, you can reform damaged flange faces subjected to harsh chemicals, crevice corrosion, galvanic corrosion, and high-pressure steam. Where long-term corrosion protection is required from the external environment, flanges, fastenings, and associated pipework can be encapsulated with a peelable and resealable coating specifically designed to exclude moisture and prevent atmospheric, galvanic, and crevice corrosion. Belzona flange face repair solutions offer long-term protection of the flange which is far less susceptible to damage and leakage in the future.
