Industry:

Application:

Ships and Offshore Structures (SOS)

 
 

Customer Location:

Dockyard, Bulgaria

 
 

Application Date:

February, 2009

 
 

Application Situation:

Oversized housing and keyway of rudder pintle.

 
 

Problem:

Keyway and rudder pintle housing were oversized due to erosion corrosion and impact.

 
 

Products:

Belzona® 1111 (Super Metal)

Belzona® 1221 (Super E-Metal)

 

Substrate:

Cast Iron

 
 

Application Method:

Application procedures were made according to Belzona Know-How System Leaflet SOS-3. The oversized housing and keyway were rebuilt  using the rudder pintle with a false key as former. Belzona® 1111 was used for the main repair and Belzona® 1221 was used to fill some voids along keyway.

 
 

Belzona Facts:

The repair was done on-site and completed in a few hours. In this situation conventional repair by welding and then machining was considered to be time consuming, complicated and too expensive.
