After 10 years in service these "ducks feet", situated at the bottom of the CW pipework, were found to be in very bad condition. There were 4 units to re-furbish.

Belzona® 1321 (Ceramic S Metal) 

 

Substrate:

Steel

 
 

Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflets VPF-1 and -2. Substrate was washed and blasted several times to remove salts and to provide correct surface for application. The badly eroded areas were re-built with Belzona® 1311 and then each was given 2 coats of Belzona® 1321.

 
 

Belzona Facts:

The power station were not only delighted with the re-furbished items, but the speed of the service and significant savings on new equipment. At the time Belzona contractor were coating the CW Pumps.
