Belzona® Flange Repair System Eliminates Blushes On New Process Vessel

 
 

Industry:

Marine (MRNE)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Vessel manufacturer - UK

 
 

Application Date:

April 2004

 
 

Application Situation:

Nozzle flange faces on offshore process vessel due for urgent delivery

 
 

Problem:

During surface preparation prior to the installation of a Belzona coating, grit blasting damage had occurred to four internal nozzle flange faces. As a result of this the sand recovery system due to be installed could not be fitted.

 
 

Products:

Belzona® 1591 (Ceramic XHT Metal)

 

Substrate:

Stainless steel.

 
 

Application Method:

The flange faces were reblasted fully and Belzona® 1591 was installed using a forming process according to Belzona Know-How System Leaflet VPF-13.

 
 

Belzona Facts:

Four flange faces were formed using this technique, and were allowed to cure prior to breaking out. Once complete they were protected, the vessel was grit blasted for a second time and Belzona® 1591 applied to the whole vessel. The alternative would have required on-site machining of the flange faces at significant cost.
