The Retractable Strip Corrosion and Scale coupon   a comprehensive range of weight loss coupons and holders covering applications in oil & gas, refinery and processing, water treatment and general industry.

Corrosion Inhibitor is a water based corrosion inhibitor formulated.

It will effectively inhibit corrosion caused by H2S, CO2 salt water and other elements. Designed to provide good film persistency and is dispersible in fresh and brine water. Low points in the bottom of flow lines where water has collected are protected because of the solubility of the product.

CHARATERISTICS:
Appearance Clear Liquid
Color Light Brown
Specific Gravity @ 25°C 0.95 – 0.99
pH 7 ~ 9
Solubility Water soluble, oil dispersible

APPLICATION:
A rule-of-thumb dosage rate is 10 – 20 ppm based on water production. This should be varied in accordance with the severity of the problem. Frequency and method of application vary over a wide range, depending upon individual characteristics.

STORAGE AND HANDLING:
Corrosion Inhibitor is non-flammable liquid. Use in well ventilated area. Keep container tightly closed when not in use. Wear appropriate PPE.

PACKAGING
Packaging in 200 liters drum.
