    Cortec VpCI®-637 GL | Inhibitor for Gas Flow and Transmission Lines | 5 Gal (CUSTOM PRODUCT)

    VpCI®-637/637 GL provides effective internal corrosion control in natural gas and crude oil gatherings and transmission lines.

    VpCI®-637/637 GL are a combination of vapor phase, neutralizing, and film-forming corrosion inhibitors to combat the broadest range of corrosive attack from moisture and condensation, oxygen, carbon dioxide, hydrogen sulfide, and other corrosive contaminants in natural gas and petroleum. These non-emulsifying formulations offer the benefits of filming inhibitors that form a tenacious protective film on metal surfaces; neutralizing inhibitors that combat corrosive fluid formation and vapor phase inhibitors that reach areas inaccessible by direct contact to protect areas subject to varying flow ratios.

    The unique chemistries of VpCI®-637/637 GL allow these products to provide excellent protection in “sweet/ sour” saturated carbon dioxide/hydrogen sulfide environments.

    According to results obtained from the Wheel Test (NACE test method publication ID182), VpCI®-637/637 GL provides excellent protection in both continuous and intermittent treatments; due to exceptional film persistency.

    Cortec is a world leader in rust and corrosion removal and protection. Cortec VpCI® products offer cost-effective and environmentally friendly corrosion protection solutions that are bio-degradable, self replenishing and provide multi-metal protection.


    • Effective for a wide range of systems and corrosive conditions
    • Provides maximum control over long distances for highly corrosive systems having a high ratio of water- to-hydrocarbons, including low areas in systems where water collects and extreme corrosive attack occurs
    • Form an adsorbed, protective layer that protects ferrous and non-ferrous metals
    • Effective against water, corrosive gases, and halogens
    • Vapor phase action provides protection from atmospheric conditions and moisture condensation to areas not accessible by filming inhibitors
    • Recommended concentrations do not cause foaming or upsets in gas sweetening or glycol dehydration processes
    • Does not contain heavy metals, chlorinated hydrocarbons, or volatile amines
    • Provides cost effective solution
    • VpCI®-637 GL does not affect foaming properties in the natural gas processing

    PACKAGING AND STORAGE: This product is packaged in 5 gallon (19 liter) containers. VpCI®-637 GL is also available in 55 gallon (208 liter) metal drums, liquid totes and bulk.
