Corrosion Under Insulation – Process Conditions to Watch Out

Armorgelä premium anti-corrosion gels are engineered to mitigate critical CUI & CUF causative conditions such as all externally insulated and fireproofed Systems and those that are in intermittent service or operate between:

• 10°F (–23°C) and 350°F (176°C) for carbon and low alloy steels.
• 140ºF (60°C) and 400ºF (205°C) for austenitic stainless steels and duplex stainless steels.
• Environments that provide airborne contaminants such as chlorides (marine environments, cooling tower drift) or SO₂ (stack emissions) can accelerate corrosion and Plants located in areas with high annual rainfall or warmer, marine.
• Cyclic thermal operations, intermittent service and cryogenic service equipment that operate below the water dew point which create condense water on the metal surface resulting into wet insulation.
• Insulating materials that hold moisture and contaminants that may be leached out of the insulation, such as chlorides.
