OLKLIN®-OLCI
Oil Line Corrosion Inhibitor
Description:
The corrosion typically encountered in the transport of a fluid containing one or more fluid (corrosion agents) is flow-induced corrosion. In the case of flow-induced corrosion, the degree of corrosion that occurs is generally depend on a variety of factors like corrosiveness of the fluid itself, the metallurgy of the pipeline and the shear rate, temperature, and pressure of the fluid.
A corrosion inhibitor is frequently introduced into the fluid to reduce the rate of corrosion of the metal vessel, pipeline and/or equipment used to store and transport the fluid.
Chemical Composition:
It is composition of organic specified amines with dispersant.
