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 pressure (including vacuum), depending on the design pressure of the steel body.
Steel-lined plastic storage tanks offer advantages such as seamless construction, non-leakage, non-toxicity, resistance to aging and impact, corrosion resistance, long service life, and compliance with hygiene standards. They address the shortcomings of fully plastic rotational molding tanks, such as poor rigidity and strength, poor pressure resistance, and temperature sensitivity. The inner lining of the product is flat, smooth, and sturdy. Compared to traditional steel-lined plastic board tanks, rubber-lined storage tanks, and glass fiber reinforced plastic storage tanks, they have 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 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 overall plastic 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.].
