Steel-Plastic Composite Product Introduction

The steel-plastic composite storage tank is made from polyethylene (PE) and polyolefin (PO) as raw materials, utilizing spinning molding technology for one-time integral molding. The steel mesh is welded to the surface of the tank, forming an integrated structure with the tank surface, steel mesh, and plastic. Compared to traditional steel-lined plastic or glass fiber-lined steel 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 drum body, flat bottom, top cover, manhole, inlet flange, outlet flange, and liquid level hole flange. Horizontal steel-lined plastic storage tanks typically also include standard steel supports. 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 requirements, ranging from 0.5 to 80 m³.

Features of steel-plastic composite steel-lined plastic products

The product has a smooth, glossy, and sturdy plastic-coated surface. Compared to traditional steel-plastic and steel-glass lined products, 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 users.
