Three principles to follow when selecting materials: a) The material’s corrosion resistance must meet the requirements of production. b) The material’s mechanical properties and workability must satisfy the needs of equipment design and manufacturing. c) Cost savings should be considered. When choosing materials, priority should be given to those metals and alloys that have corrosion resistance suitable for the working environment, good overall performance, and relatively low costs. 2. Protective coating: The anti-corrosion coating must meet the following requirements: a Good adhesion to the metal ； b Good electrical insulation properties ； c Waterproof, high chemical stability ； d It is heat-resistant, possesses high mechanical strength and toughness, and can be protected from damage due to collisions during construction ； The e structure is compact and completely pore-free.
