Substrate: Cast iron and steel
Customer Location: Fossil fuel power station in Australia
Application Date: November 1993
Belzona® 1341 (Supermetalglide)
Problem: Corrosion damage to the end covers and impeller, as well as heavy souring of the gland packing locations on the impeller shaft caused insufficient vacuum pumping and loss of pressure.
- Scored area of the shaft
- Undercoat area of the damaged shaft
- Application of Belzona® 1131
- The rebuilt shaft after machining of Belzona® 1131
Water ring vacuum pump for main condenser.
The application was carried out in accordance with Belzona Know-How System Leaflets MPT-1 and CEP-7.
Customer achieved an increase in efficiency. In particular the end covers were rebuilt with Belzona® 1131 for additional security in service. As the clearances increase between the vanes of the rotor and the end covers, the Belzona® 1131 will prevent hang up, and provide a smooth hydrodynamic surface.
