Quaternary Ammonium Oilfield Corrosion Inhibitor

Quaternary ammonium-based corrosion inhibitor provides effective protection of carbon steel equipment and pipelines in oilfield water injection, production, and transportation systems. It functions through adsorption onto metal surfaces, forming a hydrophobic barrier against corrosive species including chloride ions, dissolved oxygen, CO₂, and H₂S. The product combines corrosion inhibition with bacteriostatic activity.
