The lining of a vessel at a Glasgow-based brewery required a complete overhaul. The coating started to flake and the underlying substrate was left exposed.
A new system that prevents metal loss or contamination needed to be installed. The coating also needed to have food and water grade approvals for use in high temperatures.
The brewery turned to Belzona.
“The maintenance manager discussed the vessel lining issue and we were happy to propose our solutions for further testing,” said Douglas Potts, field sales engineer for Belzona UK. “Sample plates were required to taint test the Belzona coating, whilst a ‘supply and fit’ proposal from our application arm, Belzona Technosol, also had to go through vetting and approval.
“Our recommendation, Belzona 5892, passed with flying colors.”
The application on the 24.7-foot tall vessel – which is also 10.7 feet in diameter – took two weeks to complete. The existing lining was coated.
The hand-applied Belzona 5892 allowed the vessel to remain in place for the application.
This helped “[avoid] the costs associated with dismantling and transportation elsewhere,” Potts said.
To get the tank back in service quickly, infrared heaters were employed to conveniently reduce the cure time.
Using sponge blasting in lieu of grit kept dust levels down. This was further helped by tenting.
“By coating, we have significantly extended the life of the vessel and we are already in discussions for future tanks,” Potts said.
This WRAS-approved system can be installed in two coats without the need for any specialist equipment.
The one challenge was the door – the 40 mm x 500 mm access hatch needed to be removed during the recoating.
Cleanliness is extremely important in the brewing process.
Belzona 5892 is formulated with a smooth and glossy surface which aids in cleaning. The product has good all round chemical resistance which means it is resistant to commonly used cleaning solutions/chemicals. It is also resistant to steam cleaning; high heat resistance (high HDT and Tg) and steam-out resistant (96hrs at 210°C).
Five major breweries in the UK – and others worldwide – use Belzona coatings.
