CORROSION INHIBITOR

Asset Integrity

CORROSION INHIBITOR


The effectiveness of an FFCI is partly determined by the strength of its adsorption to the metal surface(or a ferrous scale such as siderite, iron carbonate), forming a protective layer that physically prevents corrosive chemicals such as water and chloride ions from penetrating to the metal surface.

DESHI has developed a broad range of products that can be used to tackle oilfield corrosion. They can provide corrosion inhibition in a variety of forms, including oil-soluble, oil-soluble/water-dispersible and water soluble.
