The steel-lined plastic storage tank in the existing technology has the advantages of no welding seams, no leakage, no toxicity, anti-aging, impact resistance, corrosion resistance, long life, and compliance with health standards. It makes up for the shortcomings of poor rigidity, poor pressure resistance, and temperature resistance of all-plastic rotational molding storage tanks. The inner lining surface of the product is flat, smooth, and strong. Compared with traditional steel-lined plastic plate storage tanks, steel-lined rubber storage tanks, and steel-lined fiberglass storage tanks, it has better corrosion resistance, no leakage, no peeling, wear resistance, resistance to certain pressure, resistance to higher temperatures, and longer life. Its price is lower than that of traditional storage tanks of the same specifications, and it is an ideal container for storing corrosive liquids. Therefore, it is an extremely excellent corrosion-resistant storage tank. The overall rotational lining plastic layer is formed in one step, without joints, strong and durable, sanitary and clean, resistant to various acids and alkalis, and resistant to any concentration of hydrofluoric acid, hydrochloric acid, phosphoric acid, etc.
