Corrosion Scale Inhibitor - Amersperse Corrosion And ...
Corrosion and deposition are common problems associated with these systems. If not properly controlled, corrosion of process equipment and mill piping can negatively impact equipment life, pumping efficiency and maintenance costs. Metals such as iron, manganese and calcium, which may be present in the mill water, can cause deposition.

Abstract. While NaNO 2 addition can greatly inhibit the corrosion of carbon steel and ductile cast iron, in order to improve the similar corrosion resistance, ca. 100 times more NaNO 2 addition is needed for ductile cast iron compared to carbon steel. A corrosion and inhibition mechanism is proposed whereby ion is added to oxidize. The ion can be reduced to nitrogen compounds and these ...
