Industry:

Power (POWR)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Power Station, UK

 
 

Application Date:

May 2001

 
 

Application Situation:

Main intake pipework drawing sea water into the power station.

 
 

Problem:

As a relatavely new power plant on the banks of tidal estuary, the CW pumps and ancillary pipe work were showing significant erosion and corrosion after a short period of service. They were pumping large volumes of water from the river, which is very erosive even after it has been screened.

 
 

Products:

Belzona® 1311 (Ceramic R-Metal)

Belzona® 1321 (Ceramic S-Metal)

 

Substrate:

Mild Steel

 
 

Application Method:

Application was carried out in accordance with Belzona System Leaflets VPF-1 & VPF-2. Particular attention was paid to washing and blasting to remove salts, then badly eroded areas were re-built with Belzona® 1311 and then two coats of Belzona® 1321 applied.

 
 

Belzona Facts:

The first bend, which is shown in the photographs, was opened up in March 2007 with a view to being refurbished. However when it was inspected, it was found to be in perfect condition.
