Steel-Plastic Composite Product Introduction

The steel-plastic composite storage tank is made from polyethylene (PE) and polyolefin (PO) as raw materials, utilizing rotational molding technology to form a single piece. 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 or glass fiber-lined steel tanks, this steel-plastic composite storage tank boasts both high physical and mechanical properties and high resistance to chemical corrosion.

Steel-plastic composite lined steel products typically consist of the drum body, flat bottom, top closure, manway, inlet flange, outlet flange, and liquid level hole flange. Horizontal steel-lined plastic storage tanks usually 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 features a smooth, glossy, and robust plastic-laminated surface. Compared to traditional steel-lined plastic or glass-lined steel, it offers superior corrosion and wear resistance, and a longer service life. It is an ideal product for transporting corrosive liquids and is widely used in the chemical, rare earth, metallurgy, and pesticide industries for low-pressure tanks, vacuum vessels, reactors, and exchange columns below 100 degrees Celsius, enjoying great popularity among users.
