WebCorr provides corrosion consultancy services, corrosion expert witness and corrosion short courses for in-house training, online and distance learning. corrosion types, corrosion forms, pipe corrosion, generalized corrosion what causes corrosion?Corrosion of Metals: Causes, Factors, Theories, Forms and what causes corrosion?The term corrosion is defined as an act or process of gradual wearing away of a metal due to chemical or electro-chemical reaction by its surroundings such that the metal is converted into an oxide, salt or some other compound. A substance known as the rust results from such a process.
Uncontrolled humidity and corrosive gases are the primary causes of corrosion in industrial environments. Condensation of water vapor on metal surfaces and corrosive gases such as ammonia, chlorine, hydrogen oxides, sulfur oxides, etc. can result in corrosion of electronic equipment, rusty corners, and corroded parts. Sustained exposure to humid conditions in combination with polluted air Copper Pipe Corrosion - US Water SystemsOne of the main symptoms of pipe corrosion is blue-green stains on your sinks, showers, faucets, drains, and other plumbing fixtures. The copper pipe green corrosion is caused by the copper being dissolved out of the pipes and then deposited elsewhere. You may also find tiny, pinhole leaks in your pipes as the copper is slowly worn away.Causes of Corrosion - Mountain Empire Community CollegeCarbon dioxide in water also tends to cause corrosion. The carbon dioxide gas can combine with water to form carbonic acid, which lowers the pH of the water. As mentioned in the last section, a low pH promotes corrosion.
Hydrogen-sulfide corrosion, or H2S corrosion, occurs as an acid attack caused by the biological conversion of hydrogen-sulfide gas (H2S) to sulfuric acid (H2SO4), in the presence of moisture.
