Pipeline Internal Corrosion Inhibitor
Pipeline internal corrosion inhibitor is a specially formulated blend of imidazoline, quaternary ammonium compounds, and film-forming amines designed for continuous or batch injection into crude oil and gas transmission pipelines. It provides comprehensive protection against CO₂, H₂S, organic acid, and chloride-induced corrosion, achieving corrosion rates below 0.1 mm/year. Suitable for both water-wet and oil-wet pipeline sections under multiphase flow conditions.
