Introduction:            ( 1) Electrochemical corrosion       The corrosion caused by the action of metal in contact with electrolyte solutions such as acid, alkali and salt is called electrochemical corrosion. It is characterized by the current generated during the corrosion process, and the corrosion products are not covered on the surface of the special-shaped tube as anode, but at a certain distance from the anode metal.      ( 2) Intergranular corrosion       This kind of corrosion is carried out along the grain edge inside the pipe, which usually does not cause any change in the shape of the metal
