Belzona® Flange Repair System Saves Money

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Offshore Oil Company - UK North Sea

 
 

Application Date:

November 2003

 
 

Application Situation:

Flange faces on 16”, 300lb crude oil transfer hoses

 
 

Problem:

External corrosion on the flange faces had resulted in the hoses not being able to seal correctly and as a result were considered no longer fit for purpose.

 
 

Products:

Belzona® 1321 (Ceramic S-Metal)

Belzona® 9411 (Release Agent)

 

Substrate:

Galvanised steel.

 
 

Application Method:

A procedure based around Belzona Know-How System leaflet VPF-9 was used to reform the flange faces.

 
 

Belzona Facts:

The four hoses shown in the picture represent a cost to the customer if replaced of approximately £100,000 ($160,000). All four hoses were effectively covered and tested to 18 bar according to International (OCIMF 1991) and Dunlop Oil & Marine Test Guidelines. This was done for a fraction of the cost of replacement hoses.
