I. Product Overview 
The stainless steel storage tank is a sealed material storage device made from SUS304 and SUS316L food-grade/industrial-grade stainless steel as the core raw materials. It is precisely cut, welded, polished, and tested under pressure through multiple processes to be refined. It has multiple functions such as material storage, mixing and blending, temperature control and insulation, and anti-corrosion sealing. According to the different usage requirements of different industries, it can be customized with various models including normal pressure/pressure, vertical/horizontal, single layer/layered, hygienic grade/industrial grade, etc. It has core advantages such as corrosion resistance, easy cleaning, long service life, and environmental friendliness without pollution. It is widely applicable to the storage and processing of liquid, semi-fluid, and powder materials in multiple industries such as food, pharmaceuticals, chemicals, dairy products, cosmetics, and water treatment, and is a necessary general equipment for modern industrial production and material storage and transportation. 
II. Product Classification and Specifications 
(1) Classification by structural form 
Vertical stainless steel storage tank: With a vertical cylindrical structure, it occupies a small area, has a large storage capacity, a stable center of gravity, and is easy to install. It is available in two models: flat bottom and conical bottom. The conical bottom design enables complete material discharge without any residue or liquid accumulation. 
2. Horizontal stainless steel storage tank: With a horizontal cylindrical structure, it has a low center of gravity and strong pressure resistance, making it easy to be moved and transported. It is suitable for vehicle transportation, scenarios with limited space, and high-pressure working conditions. It is the preferred choice for storing small-capacity materials. 
(II) Classification by Function and Purpose 
Single-layer stainless steel storage tank: A basic type of storage equipment with a simple structure and low cost. It is suitable for the sealed storage of regular materials at normal temperatures without the need for temperature control. 
2. Insulation/Heating Stainless Steel Storage Tank: Double-layer jacketed/multi-layer insulation structure, capable of being filled with insulation materials such as polyurethane and rock wool. It supports temperature control methods like steam, heat transfer oil, and electric heating, enabling constant temperature storage and heating insulation of the materials, preventing freezing and deterioration at low temperatures. 
3. Hygienic stainless steel storage tanks: Strictly adhering to GMP and FDA hygiene standards, the inner walls are electrochemically polished to a mirror finish, with no welding blind spots or burrs, easy to clean and disinfect, and capable of eliminating bacterial growth, suitable for high-cleanliness scenarios such as food, pharmaceutical, and dairy industries. 
4. Stirring type stainless steel storage tank: Equipped with a professional stirring motor and stirring paddle, it can achieve material mixing, homogenization, prevention of sedimentation, and simultaneous storage and stirring. It supports variable frequency speed control and can meet the processing requirements for different viscosity materials. 
(III) Core Specifications 
• Material selection: SUS304 stainless steel (general model), SUS316L stainless steel (high corrosion resistance model), specially customized duplex steel/titanium steel (for severe corrosive conditions) 
• Volume range: 50L - 500m³, supports customized production of any volume. 
• Design pressure: Atmospheric pressure 
• Design temperature: -20℃ to 160℃ 
• Standard accessories: manhole, feed port, discharge port, ventilation valve, liquid level gauge interface, thermometer interface, cleaning port, flange/fastening interface 
III. Core Product Advantages 
Durable and long-lasting: The surface of the stainless steel material forms a dense passivation film, which is resistant to acids and alkalis, anti-oxidation, anti-rust, and does not undergo chemical reactions with various materials. Compared to carbon steel storage tanks, its service life is extended by 3 to 5 times, and it is unlikely to deform or break even after long-term use. 
2. Sealed and clean, ensuring quality: The fully automatic argon arc welding process results in uniform and smooth welds. It undergoes 100% water pressure testing and air tightness inspection to prevent any leaks. The fully enclosed structure isolates external dust, impurities, and microorganisms, preventing material contamination and deterioration. The hygiene-grade design complies with food and pharmaceutical safety standards. 
3. Well-designed, easy to use and maintain: The tank has a non-angled design, with a smooth inner wall that does not adhere to materials. Cleaning and disinfection operations are simple; standardized interfaces can quickly connect to pipelines, pump bodies, and mixing equipment. The manhole design facilitates later maintenance and internal cleaning, and no special maintenance is required on a daily basis. 
4. Highly customizable and highly adaptable: Based on the material properties, storage capacity, installation site, and functional requirements, the product can be flexibly customized in terms of material, volume, structure, and accessories. It can be adapted to the individualized usage needs of different industries and working conditions, achieving multi-purpose use and reducing equipment investment costs. 
5. Environmentally friendly and safe, with high compliance: No harmful substances are released, it does not pollute materials or the environment. It complies with national environmental protection and food safety production standards. It can pass industry qualification tests and meet the compliance operation requirements of various manufacturing enterprises.
