How is the wall thickness of plastic storage tanks determined

Plastic storage tanks are used to store refined chemical substances such as acids, alkalis, alcohols, and gases. We have observed that their wall thickness varies, as it depends on the type of liquid being contained. The wall thickness of plastic storage tanks can be adjusted according to the density of the liquid they hold. They are commonly used for storing water or alkaline/acid liquids with concentrations below 30%, and can accommodate solutions at temperatures below 60°C. If plastic storage tanks are used to store acidic or alkaline chemical liquids, the wall thickness should be appropriately increased.

The performance of plastic storage tanks surpasses that of traditional fiberglass and welded plastic containers. Fully plastic PE tanks exhibit twice the corrosion resistance and service life of fiberglass, making them capable of replacing materials such as stainless steel, titanium, nickel, and alloy steel within a wide range.

Compared to traditional corrosion-resistant storage tanks, plastic storage tanks are cost-effective and offer high value for money. Fully plastic PE storage tanks can store and transport the majority of inorganic acids, alkalis, salt solutions, and some organic solvents. During the winding process of plastic storage tanks, in addition to circumferential winding, spiral winding is also introduced. The winding angle can be designed based on the stress conditions of the product and adjusted within the range of 65° to 85°.

This helical winding breaks through the traditional concept that storage tank products are laminated structures, not only enhancing the axial strength of the products but also significantly improving the overall structural performance of the tanks, such as interlaminar shear strength, bending strength, creep resistance, wind resistance, and seismic resistance.

Currently, such plastic storage tanks are primarily suitable for material storage and temporary storage in industries such as chemicals, petroleum, pharmaceuticals, food, oils, printing and dyeing, metallurgy, environmental protection, and light industry. They not only ensure the quality of solutions but also extend the service life of the containers.
