A process vessel, in America, experienced a brick and mortar lining failure resulting in the process environment consuming the carbon steel shell 90ft above ground. A full repair would have required over a week of unscheduled downtime, so a quotation request was sent out to contractors for an external patch that would not further degrade the internal liner.

All proposed options, other than that from Corrocoat USA called for welding, risking further damage to the liner. Corrocoat’s proposal – to apply a composite patch to withstand the corrosive 80C environment – required less time and eliminated the risks of welding while requiring less than half the investment. The proposal was accepted.

The area was scraped carefully by hand, exposing a five foot vertical void in the shell surrounded by smaller voids. The thinner areas near the voids were prepared with power tools to protect the integrity of the liner, the surfaces washed to remove salts prior to abrasive blasting and priming with Corroglass 600 Series.

Corroglass 600 Series is specifically developed for process internals, resisting chemical laden environments. It includes a lamination resin and barrier linings of three different viscosities that can hang up to 3mm without sagging, and be applied wet-on-wet in films of up to 8mm. This eliminates the long wait times between layers with other composite repairs.

The work was successfully completed without the need for potentially damaging hot work in a very exacting time period.

As well as our specialist range of paints and coatings, we’re proud to offer a wide selection of corrosion engineering services, including everything from inspection, cleaning and manufacturing, to repair, refurbishment and support. When it comes to protection, we are solid in our approach – and our performance.
