Steel-plastic lined storage tanks, also known as turtle shell lined tanks (turtle shell lining - steel, mesh, plastic combined), are the essence of the steel-plastic composite product series. They are manufactured using a special rotational molding process. This involves welding a steel mesh (turtle shell) to the surface of the steel body, and then using pure polyethylene (linear low-density polyethylene LLDPE, high-density polyethylene HDPE) as the material, to integrate the steel plate, steel mesh (turtle shell), and polyethylene into a single unit through rotational molding. The polyethylene is securely bonded to the surface of the steel body. The product features seamless joints, non-leakage, non-toxicity, resistance to aging and impact, corrosion resistance, long lifespan, and compliance with hygiene standards. It overcomes the drawbacks of plastic-lined storage tanks, such as poor rigidity, low pressure resistance, and temperature sensitivity. The interior lining is smooth, flat, and robust, offering superior corrosion resistance, non-leakage, non-peeling, wear resistance, pressure resistance, high-temperature resistance, and longer lifespan compared to traditional steel-lined plastic plate tanks, steel-lined rubber storage tanks, and steel-lined fiberglass storage tanks. Its price is lower than that of similar traditional storage tanks, making it an ideal container for storing corrosive liquids. Therefore, it is an extremely excellent corrosion-resistant storage tank.
2. Application Scope
a. Medium: Pure water, liquid food, acids, bases, salts, and some organic solvents (resistant to certain concentrations of hydrochloric acid, phosphoric acid, hydrofluoric acid, etc.).
b. Temperature Resistance: -65℃ to 98℃
c. Pressure Resistance: Positive and negative pressure (including vacuum) as determined by the design pressure of the steel body.
3. Unique Advantages
The entire lining is formed in one piece, seamless, sturdy and durable, hygienic and clean, and resistant to various acids and alkalis [resistant to any concentration of hydrofluoric acid, hydrochloric acid, phosphoric acid, etc.].
Advantages: Long lifespan, excellent insulation, and the reaction medium does not come into contact with metal ions.
4. Specifications and Models
Vertical steel-lined plastic storage tanks (flat bottom, conical bottom) and horizontal models are available in a series. Various storage tanks can also be customized as required. Generally, the specifications for vertical steel-lined plastic storage tanks, steel-plastic composite vertical storage tanks, and tortoise shell-lined storage tanks range from 1 cubic meter to about 150 cubic meters.
5. Application
Steel-lined plastic storage tanks are widely used in industries such as chemicals, dyes, metallurgy, rare earths, machinery, electricity, electronics, environmental protection, textiles, brewing, food, water supply, and drainage.
