Why is stainless steel coil used on storage containers

source：m.tzjbxx.cn | Release time：2025年01月01日

The use of stainless steel coils on storage containers is mainly based on the following reasons:
1. Excellent corrosion resistance
Anti medium erosion: Storage containers often need to hold various liquids, gases, or solid materials, such as acid-base solutions in the chemical industry, fruit juice and milk in the food industry, and various pharmaceuticals in the pharmaceutical industry. The surface of stainless steel coils will form a dense and stable oxide film, which can effectively block external water vapor, oxygen, and these corrosive storage media, prevent the tank from being corroded and rusted, maintain the structural integrity of the storage container, and greatly extend its service life. For example, 304 stainless steel coils can resist general atmospheric corrosion and freshwater corrosion, ensuring long-term stability of the container in daily environments; 316 stainless steel coil contains molybdenum element and has good resistance to more corrosive substances such as chlorine containing media and seawater.
Maintaining material purity: The corrosion resistance of stainless steel not only protects the container itself, but more importantly, prevents chemical reactions between the container material and the stored material, prevents impurities from entering, and ensures that the material maintains its original quality and purity. This is extremely important in industries such as food and pharmaceuticals that have strict requirements for product quality.
2. Good mechanical performance
High strength and toughness: Stainless steel coils have high strength and can withstand the weight of stored materials, pressure changes during filling and emptying, as well as external impacts that may be encountered during transportation and handling, without easily deforming or breaking. At the same time, its good toughness enables it to absorb energy through its own deformation instead of brittle fracture when subjected to sudden external forces, ensuring storage safety. For example, when a large vertical stainless steel storage tank is filled with liquid, the tank wall must withstand enormous hydraulic pressure, and the high strength and toughness of stainless steel ensure the stability of the tank body.
Strong processing adaptability: Stainless steel coils have excellent ductility and can be easily processed into various shapes and specifications of storage container components through rolling, welding, stamping, bending and other processes, such as cylindrical tanks, elliptical heads, various pipeline interfaces, etc., to meet different design and usage needs. They can also achieve complex internal structures, making it easy to install functional components such as mixing, heating, and cooling.
3. Sanitary and easy to clean
Surface characteristics: The stainless steel coil material has a smooth and flat surface, making it difficult for microorganisms and dirt to adhere. Daily cleaning only requires simple wiping and rinsing. In industries with high hygiene requirements such as food and pharmaceuticals, this ease of cleaning can eliminate the hidden dangers of bacterial growth and cross contamination, fully complying with the hygiene standards and regulations of relevant industries. For example, stainless steel tanks for storing yogurt can be maintained in a clean and sterile state by regularly rinsing them.
No harmful substance release: Stainless steel itself is non-toxic and harmless, and will not release heavy metals, harmful chemicals, etc. into stored materials, effectively ensuring the safety and quality of sensitive materials such as food and medicine.
4. Beautiful and durable
Appearance advantage: The stainless steel coil has a metallic luster and a simple and modern appearance. After being made into a storage container, it does not require additional decorative treatments such as painting or coating, and can present a beautiful and elegant visual effect, which complements the modern industrial plant and clean workshop environment.
Long lifespan: With comprehensive advantages such as corrosion resistance and mechanical properties, storage containers made of stainless steel coils are durable and reduce the adverse effects of frequent container replacement, such as cost investment and production stagnation. In the long run, the cost-effectiveness is very high.
