Tankroof Cold Repair

Problem

Almost all roof surface has large and small holes due to corrosion and deterioration.

Application situation was cold repairing is required as the tank can not be taken in shut down. Hot work is not permitted except drilling and grinding on some areas.
Different size of metal plates were used to strengthen the corroded area and repaired the holes with recommended cold weld / repaire product. Nine tanks roofs from 50ft to 120ft diameter have been protected.
