Storage tanks are sealed container equipment used for long-term or temporary storage of liquids, gases, slurries, and some solid materials in industrial and civilian fields. They often serve as storage, buffering, and blending units in the production chain. Their design and manufacture must comply with national/industry standards for pressure vessels/atmospheric pressure storage tanks (such as GB 50341, API 650, GB 150). They are characterized by high strength, good sealing, resistance to medium corrosion, and stable operation, and are widely used in industries such as petrochemicals, food and pharmaceuticals, environmental water treatment, energy, and agriculture.
