NC-COR C corrosion inhibitor is an all-purpose, water-soluble organic phosphorous compound. It is a passivating type of inhibitor which forms a protective film on metal surfaces to guard against corrosion attack.
PHYSICAL & CHEMICAL PROPERTIES
|pH||7.0 - 8.0 (5% aqueous solution)|
|Solubility||Soluble in water|
NC-COR C is effective at relatively low concentrations in all water-based muds. It has proven to be particularly useful in reducing oxygen corrosion in aerated muds; low-solids, non-dispersed, polymer muds; and potassium muds.
The recommended initial treatment of NC-COR C is 2 to 4 gal/100 bbl (0.5 - 1.0 l/m3) depending on anticipated conditions, other chemicals used in the system, and the corrosive environment, i.e. salinity, pH, temperature, oxygen content and acid gases.
NC-COR C is available in 55 US gallon (208-l) drums, palletized as 4 drums per pallet.
