     In order to improve the corrosion resistance and service life of steel tanker tanks, corrosion-resistant materials or anti-corrosion linings can be sprayed on the surface of the tank body. Common methods of processing are:

       (1) Zinc coating: It is used to transport gasoline, benzene, mixed xylene, cement, water, excrement and other materials.

       (2) Tin coating: used for shipping light oil, heavy oil, lubricating oil and other petroleum products.

       (3) Lead: Pure lead is a good corrosion resistant material. Lead-coated tanks are suitable for shipping dilute sulfuric acid, chlorinated benzylic materials, and are not suitable for shipping hydrochloric acid and alkalis. Lead and its alloys are toxic and should not be exposed to food items. They are also harmful to humans and should be protected when used.

       (4) Aluminum coating: used for shipping chemical products such as methanol, ethanol, aviation fuel, concentrated nitric acid, glacial acetic acid, benzene, aldehydes, organic solutions, and food products.

     (5) Plastic lining: used for shipping water, liquid fuels, and some corrosive items. Different plastic varieties, its applicability is also different.

       (6) Rubber lining: The corrosion resistance of rubber varies depending on the type. Vulcanized natural rubber can resist corrosion of most inorganic acids, organic acids, alkalis, salts, alcohols, etc., but strong oxidants (nitric acid, concentrated sulfuric acid, chromic acid, hydrogen peroxide, etc.) and certain solvents (benzene, carbon disulfide , carbon tetrafluoride, etc.) have poor corrosion resistance. Nitrile rubber in synthetic rubber has good oil resistance; neoprene rubber is better in acid and alkali resistance; polyether rubber is more stable in water, oil, ammonia and alkali.

       In order to improve the corrosion resistance of aluminum cans, magnesium, manganese and other elements can be coated on the inner walls.

       The use of the tank should pay strict attention to its performance. Shipment of the corresponding items; care should be taken in the maintenance of the spray layer or lining to prevent damage, otherwise it should be repaired.
