Belzona® Replaces Ptfe Lining And Cuts Downtime

 
 

Industry:

Petrochemical (PETR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Chemical Plant, Ferrara, Italy

 
 

Application Date:

April, 2015

 
 

Application Situation:

Reactor operating between 70°C and 80°C at a Polyolefins petrochemical plant. Process fluids included salt, caustic and titanium tetrachloride.

 
 

Problem:

The original hot applied PTFE Lining required maintenance due to localised disbondment. The plant was facing a long downtime as it was not possible to conduct an in-situ repair of such a lining.  The customer was looking for a solution that was faster and easier to apply.

 
 

Products:

Belzona 1593

 

Substrate:

Steel

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet TCC-5 for protecting and rebuilding steelwork. After grit blasting to SA 2.5, a two-coat system of Belzona 1593 was hand applied to an area of 25 m².

 
 

Belzona Facts:

Belzona was chosen to replace PTFE as it reduced downtime from weeks to days and was also much easier to apply. Any future mechanical damage will be repairable in-situ.
