Corrosion protection

Belzona products have been applied to pressure relief valves on the turbine spiral casing at Ffestiniog Power Station to protect them from corrosion.

Belzona 1111 (Super Metal), a machinable repair composite was used to rebuild the heavily pitted areas of the valve before an overcoat of Belzona 5811 (immersion grade) was applied to protect against further corrosion. The latter is designed for the protection of metallic and nonmetallic surfaces operating under immersion.
