Introduction to Steel-Plastic Composite Products
Steel-plastic composite tanks are made from polyethylene (PE) and polyolefins (PO) as raw materials, utilizing rotational molding technology for one-time overall shaping. The 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-lined steel tanks, these steel-plastic composite tanks offer both high physical and mechanical strength and high chemical corrosion resistance.
Steel-plastic composite lined steel products generally consist of the barrel body, flat bottom, top cover, manhole, feed inlet flange, discharge outlet flange, and liquid level opening flange. Horizontal steel-lined plastic storage tanks usually also feature 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, as per 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 sturdy. 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.
