Belzona® Repairs Vent Gas Pipework

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Gaskets, Seals and Shims (GSS)

 
 

Customer Location:

North Sea gas producer

 
 

Application Date:

2003

 
 

Application Situation:

3" pipespool on gas platform vent system.

 
 

Problem:

External corrosion had led to severe wall thinning in numerous parts of the pipework. In addition several areas were holed and were being contained with a temporary fix. The welded nature of the pipework would have made replacement of the pipespool impossible as the vent gas pipework forms part of the platform’s safety system.

 
 

Products:

Belzona® 1111 (Super Metal)

Belzona® 9341 (Reinforcement Tape)

 

Substrate:

Mild Steel

 
 

Application Method:

During a recent platform shutdown the temporary repair was removed and the pipe and surrounding areas were cleaned by grit blasting. Belzona® 1111 was applied to the area and Belzona® 9341 wrapped around the pipe to prevent further deterioration of the corroded area.

 
 

Belzona Facts:

This was pressure tested to the design pressure of the system before allowing gas back into the system.All tests were successfully completed.
