The steel-lined plastic storage tanks have a wide range of applications. They can be used for media such as pure water, liquid food, acids, bases, salts, and certain organic solvents [resistant to certain concentrations of hydrochloric acid, phosphoric acid, hydrofluoric acid, etc.].
Temperature Resistance: -65℃ to 98℃. Pressure Resistance: Positive and negative pressure (including vacuum), depending on the design pressure of the steel body.
Steel-lined plastic storage tanks offer advantages such as seamless construction, no leakage, non-toxicity, resistance to aging and impact, corrosion resistance, long service life, and compliance with hygiene standards. They address the shortcomings of all-plastic rotational molding tanks, such as poor rigidity and strength, pressure resistance, and temperature resistance. The inner lining of the product is flat, smooth, and sturdy. Compared to traditional steel-lined plastic plate tanks, rubber-lined storage tanks, and glass-fiber reinforced plastic tanks, they have superior corrosion resistance, non-leakage, non-peeling, wear resistance, pressure resistance, higher temperature resistance, and longer service life. They are priced lower than equivalent traditional tanks and are ideal containers for storing corrosive liquids. Therefore, they are an extremely excellent corrosion-resistant storage tank. The overall steel-lined plastic layer is formed in one piece, with seamless construction, durability, cleanliness, and resistance to various acids and alkalis [resistant to any concentration of hydrofluoric acid, hydrochloric acid, phosphoric acid, etc.].
