Industry: Power
Problem: Corrosion / Erosion
Project Goal: Eliminate Corrosion
Location: Chile
Status: Completed
Products Used: CeramAlloy CP+AC used for Rebuilt, CeramAlloy CL+AC used for Protection
Project Description

These wicket gates for a Francis turbine, used in the hydroelectric industry, direct high flowing water so it hits the blades of the turbine at the most efficient angle. They suffer from constant erosion / corrosion when they are not protected properly. Most companies would toss worn wicket gates into their ‘bone yards’ and buy very expensive new gates for their turbines. ENECON contacted to prescribe a more cost effective and fast solution. It was decided to prepare the surfaces by grit blasting to remove all of the fatigued and corroded metal. CeramAlloy CP+AC was then used to rebuild the gates. CeramAlloy CL+AC, in gray, was applied as a first coat followed by CeramAlloy CL+AC, in blue, as the second and final coat.

METALCLAD CeramAlloy CP+AC is a two component, 100% solids, polymer composite specifically formulated to provide effective repair and rebuilding characteristics on all types of fluid flow equipment. For more information about METALCLAD CeramAlloy CP+AC please visit: METALCLAD CeramAlloy CP+AC
