| Hydro Turbine Guide Vanes Repaired And Protected With Belzona | | | Industry:Power (POWR) | | | Application:Centrifugal Pumps (CEP) | | | Customer Location:Power plant, Ukraine | | | Application Date:January-February 2012 | | | Application Situation:Erosion/corrosion and cavitation by pressure to the face of turbine guide vanes revealed during annual inspection | | | Problem:Erosion and cavitation of turbine vanes | | | Products:Belzona 1311 (Ceramic R-Metal)
Belzona 1321 (Ceramic S-Metal) | | | Substrate:Cast iron | | | Application Method:The application was carried out according to Belzona Know-How System Leaflet CEP-1 and FBC-2. Belzona 1311 was used to resurface the profile. Belzona 1321 was applied to improve efficiency and protect against erosion/corrosion. | | | Belzona Facts:Replacement was considered unacceptable due to a short shut down. Belzona was the only alternative. All work has been conducted in a short time, and this has allowed to minimize time and money | | | Photographs Description
