It is generally a single piece of material, suitable for use inside equipment that comes into contact with highly corrosive media. For tanks storing substances such as hydrochloric acid and dilute sulfuric acid, rubber or plastic linings are used, while steel tanks used for storing nitric acid are lined with thin stainless steel plates. Acid-resistant bricks (silicon bricks) are also widely used in villages; they can resist strong acids, and refractory brick linings can provide insulation. Enameling is actually a type of glass lining, known in industry as enameled glass. It has strong acid resistance and is widely used in industries such as food and pharmaceuticals to ensure product quality; however, it cannot be used to manufacture very large equipment.
In corrosion-resistant applications, linings are used as protective layers inside equipment that is in contact with highly corrosive substances; for example, rubber or plastic linings can be used in tanks for storing hydrochloric acid and dilute sulfuric acid. Stainless steel sheets are suitable for steel tanks used to store nitric acid. Acid-resistant bricks (silicon bricks) are widely used due to their resistance to strong acids, while refractory brick linings can provide thermal insulation. Enameling is a glass lining that is widely used in the food and pharmaceutical industries due to its excellent acid resistance, helping to ensure product quality; however, it is not suitable for manufacturing large-scale equipment. .
