OIL AND GAS
Gasket, Seals and Shims
Exposure to the elements and oil & gas process systems caused severe corrosion to exterior of sump tank bottom. Damage resulted in thin wall and through hole areas.
The Solution
Belzona 1121 was used to cold bond pre-fabricated replacement bottom on the tank. Sump Tank had to be repaired or taken out of service. Welding was not suitable option because it would have required unit shut down and loss of production, and replacement would also have caused loss of production plus cost of new tank. Off site fabrication of a new tank bottom and temporary by pass of this tank during application was the most cost effective alternative.

Separators
Wemco separators use an agitator to help separate oil from water. The agitators create flow patterns on the bottom of the vessel that cause aggressive erosion.

Heat Exchangers
The Crude oil heat exchangers operate at up to 110°C and are prone to rapid corrosion. The separator channels and tube face can all suffer extreme corrosion decreasing the life of the equipment.
The Solution
Masking tape was placed at the outer edge of the rebate grooves in order to highlight the area to be coated and to give a neat and clean finish. Then, the selected Belzona product was mixed and an even coat was applied at the specified thickness, using stiff short bristled brushes. Then, it was made sure that the coating was finished into the rebate grooves. Wet film thickness gauges were used to ensure the recommended film thickness was achieved. The masking tape was removed immediately. Allow to cure before applying a second coat, where specified, of the selected Belzona product, again ensuring that it is correctly finished within the rebate grooves.
