BELZONA REPLACES PTFE LINING AND CUTS DOWNTIME
Industry: Chemical & Petrochemical (PETR)
Application: TCC-Tanks and Chemical Containment Areas (TCC)
Customer Location: Chemical Plant, Ferrara, Italy
Application Date: April, 2015
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.
- PTFE lining removed
- Belzona lining applied
- Coating thickness measured
- Inspected after 6 months in service
Reactor operating between 70°C and 80°C at a Polyolefins petrochemical plant. Process fluids included salt, caustic and titanium tetrachloride.
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 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.
