Process vessel and drum linings
Process vessels, knock-out drums, and clarifiers corrode at welds and access ports where the product chemistry thins the original liner.
What is failing
Process vessels, knock-out drums, and clarifiers corrode first at welds and access ports, where the product chemistry thins the original liner. Stagnant product and turbulence at nozzles concentrate the attack. When the liner gives out, the unit leaks or fouls and the whole process train waits on it.
How AAS does it
Our crew prepares the interior and lines it with a cold-cure system chosen for the specific service, drawing on the Belzona 4341 and 5811 immersion-grade coatings. Welds and access ports get the same continuous film as the shell, with no recoating seam left behind. The work cures at ambient temperature with no hot work in the vessel.
Typically applied with Belzona 4341, Belzona 5811, matched to the service conditions.
The vessel goes back into the process inside the existing shutdown, with welds and ports protected under one lining.
