Rust is an iron oxide, usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture.Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances.ther forms of rust exist, like the result of reactions between iron and chloride in an environment deprived of oxygen â rebar used in underwater concrete pillars is an example â which generates green rust.
Rust. Just as with any metal pipe that comes directly into contact with wastewater, the interior of cast iron pipe will rust over time. Rusting on the interior of the cast iron pipe has a two-fold effect which reduces the flow of the sewer line. First, rust on the interior of the pipe constricts the interior diameter of the pipe as it builds up. Secondly, this rust creates a rough surface which slows down the rate at which wastewater can flow across the surface. Corrosion. The real danger for cast iron pipes is corrosion.
