Introduction to Steel-Plastic Composite Products
The steel-plastic composite storage tank is made of polyethylene (PE) and polyolefin (PO) as raw materials, and is formed in one piece through rotational molding technology. A steel mesh is welded to the surface of the tank, integrating the tank surface, steel mesh, and plastic into a single unit. Compared to traditional steel-lined plastic or glass fiber-reinforced steel, this steel-plastic composite storage tank offers both high physical and mechanical strength and high resistance to chemical corrosion.
Steel-plastic composite lined steel products generally consist of the drum body, flat bottom, top cover, manhole, inlet flange, outlet flange, and liquid level opening flange. Horizontal steel-lined plastic storage tanks typically also include standard steel supports. The steel-plastic composite products are generally designed and manufactured according to customer requirements.
Steel-plastic Composite Steel Lined Plastic Product Specifications
Manufacture and produce non-standard anti-corrosion equipment such as steel-plastic composite storage tanks and reactors according to customer specifications, ranging from 0.5 to 80 m³.
Steel-Plastic Composite Steel Lined Plastic Product Features
The product's plastic-coated surface is flat, smooth, and durable. Compared to traditional steel-plastic and steel-glass linings, it boasts excellent corrosion and wear resistance, as well as a longer lifespan. It is an ideal product for transporting corrosive liquids and is widely used in industries such as chemicals, rare earths, metallurgy, and pesticides. It serves as low-pressure tanks, vacuum tanks, reactors, and exchange columns below 100 degrees Celsius, and is highly favored by customers.
