Fermented Tank Steel Lined Polyethylene Material: Made from polyethylene, utilizing rotational molding technology, it forms a single piece on the steel surface. It is an excellent corrosion-resistant product. It combines the mechanical properties of steel tanks with the corrosion resistance, slow scaling, and difficulty in microbial growth of plastic tanks, making it an ideal storage tank for transporting acidic, alkaline, saline, and corrosive liquids.

Steel-lined polyethylene storage tanks can be designed in various shapes, subject to design specifications such as appropriate diameter-to-height ratios and ease of transportation. The steel plate thickness can also be determined based on the working pressure of the tank. Rotomolded storage tanks are not widely produced due to the current challenges in technology, equipment, quality control, and the lack of unified standards. As a result, finding manufacturers with large production volumes, extensive experience, and good reputation is crucial for clients. All-plastic storage tanks are mold products, with the external dimensions and interface flanges being relatively fixed, determined by the manufacturer's molds. To ensure product quality, it is generally specified that if additional interface flanges are required: submerged flanges should be mold-formed flanges.(Proper placement)Liquid-level flanges can be used with焊接flanges. The wall thickness of the tank can be appropriately adjusted within a certain range.
