    Corrosion in Steam and Condensate Piping TLV - A Steam erosion of stainless steel piping with steam and oxygen

    Corrosion of Steel Steel piping, which is commonly used in steam systems, contains a significant amount of iron and is vulnerable to rust under certain conditions. Iron rust occurs due to the oxidation of the surface of the metal upon exposure to air and water. How does stainless steel piping work?How does stainless steel piping work?Erosion Occurring in Piping. As liquid droplets hit the inner wall of the pipe, the wall slowly wears away.
