The steel-lined plastic storage tanks have a wide range of applications. They are suitable for media such as pure water, liquid food, acids, alkalis, salts, and some organic solvents [resistant to certain concentrations of hydrochloric acid, phosphoric acid, hydrofluoric acid, etc.].
Temperature Resistance: -65℃ to 98℃. Pressure Resistance: Positive and negative pressures (including vacuum), depending on the steel body design pressure.
Steel-lined plastic storage tanks offer numerous advantages such as seamless construction, non-leakage, non-toxicity, resistance to aging and impact, corrosion resistance, long service life, and compliance with sanitation standards. They address the shortcomings of fully plastic rotational molding tanks, which lack rigidity, pressure resistance, and temperature resistance. The inner lining of the product is flat, smooth, and strong. Compared to traditional steel-lined plastic plate tanks, rubber-lined storage tanks, and fiberglass-lined storage tanks, they exhibit superior corrosion resistance, non-leakage, non-peeling, wear resistance, pressure resistance, high-temperature resistance, and longer service life. Their price is lower than that of traditional storage tanks of the same specification, making them an ideal container for storing corrosive liquids. Therefore, they are an extremely excellent corrosion-resistant storage tank. The entire rotational lining is formed in one piece, ensuring seamless construction, durability, cleanliness, and resistance to various acids and alkalis [resistant to any concentration of hydrofluoric acid, hydrochloric acid, phosphoric acid, etc.].
