KHIA ID: 10333
Industry: Chemical & Petrochemical (PETR)
Application: VPF-Valves, Pipes and Fittings (VPF)

Problem: A 30-inch glass-lined steel elbow used in aggressive chemical service had sustained localized damage to the internal glass lining, exposing the underlying steel substrate. If left unaddressed, the damaged area would have been vulnerable to chemical attack, leading to accelerated corrosion, loss of containment, reduced equipment reliability, and potentially unplanned downtime. Replacing the elbow would have been costly and required extended lead times, so the customer required a repair solution capable of restoring the damaged lining while extending the service life of the existing component.

Inspect and identify damaged lining.

Mechanically prepare the repair area.

Rebuild the damaged substrate using Belzona 1511.

Apply Belzona 1593 over the repaired section.

Application Situation
The customer had a damaged 30-inch glass-lined steel elbow in aggressive chemical service. Replacing the elbow would have resulted in significantly higher costs, longer lead times, and extended downtime. Belzona provided a practical repair solution that restored the damaged lining and returned the component to service without the need for replacement. The repair was completed at the AAS workshop, allowing the customer to minimize outage time while extending the service life of the existing asset.
Application Method
The damaged area was inspected and mechanically prepared by removing loose or damaged lining and creating a suitable surface profile. The damaged section was rebuilt using Belzona 1511 Super HT-Metal, restoring the original profile and filling defects. After curing, the repair area was prepared for coating and overcoated with Belzona 1593 to provide a chemically resistant lining. The repair was completed using standard surface preparation equipment, abrasive tools, mixing equipment, and hand application tools including spatulas and brushes to achieve the required finish.
