Sour gas is natural gas or any other gas that is corrosive due to significant content of hydrogen sulfide (H2S). Natural gas is considered sour if there are more than 5.7 milligrams of H2S per cubic meter of natural gas (4 ppm H2S by volume). Natural gas that contain less amounts of hydrogen sulfide is ...
WebThe following are common forms of specialized corrosion. 1. Galling. This corrosion occurs when stainless steel parts are forced together. Commonly seen with nuts, bolts, and other fasteners, corrosion isn’t visible until the parts are separated or disassembled. The process uses repeated passes to adjust the dimensions of the steel slowly.
