Customer Location:

Pulp and paper mill - South Africa

 
 

Application Date:

March 2001

 
 

Application Situation:

Corrosion protection at elevated temperatures.

 
 

Problem:

Magnesium Oxide fan and casing were being destroyed by a serious corrosion/erosion cycle. The process temperature was 150-165C. Although the process is dry, moist air was being sucked in through the shaft hole, corroding the steel.

 
 

Products:

Belzona® 1391

Belzona® 6111 (Liquid Anode)

Belzona® 5111 (Ceramic Cladding)

 

Substrate:

Mild Steel

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflets FBC-2 and FBC-5.

 
 

Belzona Facts:

An imitation product had been previously used and only lasted for 10-12 months. The engineers chose Belzona for a more long lasting, cost effective solution for the fan and casing. The fan blades were coated with Belzona® 1391 for outstanding erosion/corrosion protection.
