Steel-lined plastic storage tanks, also known as turtle shell lined tanks (turtle shell - steel, mesh, plastic integrated), are the essence of the steel-plastic composite product series. They are produced using a special rotational molding process. This process involves welding steel mesh (turtle shell) to the surface of the steel body, then using pure polyethylene (linear low-density polyethylene LLDPE, high-density polyethylene HDPE) as the material, and integrating the steel plate, steel mesh (turtle shell), and polyethylene into a single unit through rotational molding. The polyethylene adheres firmly to the surface of the steel body. The product boasts advantages such as seamless joints, no leakage, non-toxicity, resistance to aging and impact, corrosion resistance, long lifespan, and compliance with hygiene standards. It addresses the drawbacks of plastic-lined storage tanks, such as poor rigidity and strength, pressure resistance, and temperature resistance. The inner lining of the product is flat, smooth, and strong. Compared to traditional steel-lined plastic board storage tanks, steel-lined rubber storage tanks, and steel-lined fiberglass storage tanks, it offers superior corrosion resistance, non-leakage, non-peeling, wear resistance, pressure resistance, high-temperature resistance, and longer lifespan. It is priced lower than traditional storage tanks of the same specification and is an ideal container for storing corrosive liquids. Therefore, it is an extremely excellent corrosion-resistant storage tank.

2. Application Scope

a. Media: 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 per the designed pressure of the steel body.

3. Unique Advantages

The overall lining is molded in one piece, seamless, sturdy, durable, hygienic, and clean; 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

Steel-lined plastic storage tanks are available in a series of products including vertical (flat bottom, conical bottom) and horizontal types, with various tanks customizable as required. Generally, the specifications for vertical steel-lined plastic storage tanks, steel-plastic composite vertical storage tanks, and turtle shell lined storage tanks range from approximately 1 cubic meter to around 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 wastewater treatment.
