Introduction to Steel-Plastic Composite Products

The steel-plastic composite storage tank is made from polyethylene (PE) and polyolefin (PO) materials, utilizing spinning molding technology for a one-time integral forming process. The steel mesh is welded to the surface of the tank, creating an integrated structure with the tank surface, steel mesh, and plastic. Compared to traditional steel-lined plastic and steel-lined glass fiber tanks, this steel-plastic composite storage tank boasts both high physical and mechanical properties and high chemical corrosion resistance.

Steel-plastic composite lined steel products generally consist of the cylinder body, flat bottom, top cover, manhole, inlet flange, outlet flange, and liquid level opening flange. Horizontal steel-lined plastic storage tanks usually 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 has a smooth, glossy, and sturdy plastic-lined surface. Compared to traditional steel-lined plastic and steel-lined glass, 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, enjoying great popularity among users.
