Gaskets, Seals and Shims (GSS)

 
 

Customer Location:

South African Refinery

 
 

Application Date:

Various since 1994

 
 

Application Situation:

Plate heat exchangers

 
 

Problem:

Galvanic and crevice corrosion to the end covers of the heat exchangers was resulting in leaking around the titanium plates and loss of efficiency.

 
 

Products:

Belzona® 1341 (Supermetalglide)

Belzona® 9411 (Release Agent)

 

Substrate:

Carbon steel

 
 

Application Method:

Using a modified version of Belzona Know-How System Leaflet GSS-9, a plate is coated with Belzona® 9411 and used to form a thick layer of Belzona 1341 on the end cover. This procedure provides a perfect finish and excellent seal.

 
 

Belzona Facts:

The first application was undertaken in 1994 – following the successful trial this specification has been extended through all plants in the group. This particular example was carried out in July 1999.
