304/316 Stainless Steel Storage Tank

1. Multi-media safe water storage 

Made of food-grade 304/316 stainless steel, it can safely store drinking water, food processing liquids, and pharmaceutical purified water. It is also suitable for industrial circulating water, fire-fighting backup water, and other media. The smooth inner wall prevents impurities from falling off, thus eliminating secondary pollution of water bodies.

2. Corrosion-resistant and long-lasting protection 

It has excellent corrosion and rust resistance, can withstand weak acid and alkali and humid environments, and is suitable for special scenarios such as coastal high salt spray areas and chemical plant areas. Compared with fiberglass and concrete water tanks, its service life is extended by 5 to 10 years.

3. Flexible expansion and customization 

It supports modular combination and size customization, with various structures such as vertical, horizontal and square available. The capacity can be adjusted according to the installation space (from tens of liters to thousands of cubic meters) to meet the water storage needs of different scenarios such as home, commercial and industrial.

4. Thermal insulation and energy saving (optional function)

It can be equipped with a polyurethane insulation layer and an outer color steel plate to achieve constant water temperature, reduce heat loss, and is suitable for applications requiring constant water temperature storage, such as solar water heating systems and hotel hot water supply, thus saving energy consumption.

5. Easy maintenance and cleaning 

The smooth inner wall is resistant to scaling and bacterial growth, requiring only periodic rinsing for routine maintenance. Access ports and drain outlets are provided for easy internal cleaning and troubleshooting, reducing future maintenance costs. (English trade version)

1. Medium 

304 Stainless Steel: Suitable for storing weakly acidic or alkaline media (pH 5-9), such as drinking water and industrial circulating water. 316 Stainless Steel: Suitable for storing seawater, chemical solutions, and other chlorine-containing corrosive media (pH 4-10). Do not store in strong acids, strong alkalis, or high-concentration organic solvents.

2. Installation 

Indoor: Dry and well-ventilated, with a flat concrete base and a maintenance space of ≥0.5m. Outdoor: Sunshade and rain protection installed; 316 stainless steel for coastal high-salt fog areas; Custom reinforced steel plates for high altitudes (>2000m).

3. Temperature 

Standard use: -20℃ to 80℃ for hot water storage / Extremely cold environments: Install insulation and take antifreeze measures.

4. Load-bearing capacity

Placed on a load-bearing base that meets the standards, large water tanks are equipped with reinforced concrete foundations; avoid areas prone to settlement and strong vibration.

1. Hygienic and clean, with no secondary pollution. 

Made of 304/316 stainless steel, it meets food-grade standards. The smooth inner wall is not prone to bacterial growth, rust, or peeling, and can be used to directly store drinking water and pharmaceutical purified water, preventing water pollution.

2. Corrosion resistant and long service life 

Withstanding weak acids and alkalis, humidity, and high salt spray environments, 304 models are suitable for civilian/general industrial scenarios, and 316 models can cope with seawater and chemical media, with a lifespan 5-10 years longer than fiberglass/concrete water tanks.

3. Lightweight and easy to install, flexible customization 

Weighing only 1/10 of a concrete water tank of the same capacity, its modular design supports vertical, horizontal, and square structures, and its size and capacity can be customized as needed. Installation requires no complex civil engineering.

4. Easy to maintain and low cost

The inner wall is not prone to scaling and only requires regular rinsing; it has a reserved inspection port and a drain port, making cleaning and troubleshooting convenient, and the later maintenance costs are far lower than those of traditional water tanks.

5. High strength and resistance to deformation 

The sheet metal is stamped and welded to form a stable structure with good impact and earthquake resistance. It is not prone to deformation or leakage when the box is empty or full of water.

1. Residential and commercial buildings 

Used for secondary water supply storage in high-rise residential buildings, and for storing domestic drinking water in hotels, hospitals, and schools. Made of food-grade 304 stainless steel to ensure water safety, the square modular structure is suitable for small spaces such as rooftops and basements.

2. Industrial production sector

For industrial circulating water storage and temporary storage of raw materials in the chemical, electronics, and metallurgical industries, the 316 stainless steel version can withstand chlorine-containing and weakly corrosive media; it can also be used with boiler systems to store softened water to prevent scaling from affecting equipment efficiency.

3. Fire protection engineering support 

As a backup fire water tank, it stores emergency water for fire fighting. Its large-capacity square modular design can meet the fire water demand of building complexes and is compatible with indoor and outdoor fire protection systems.

4. Solar/Heat Pump Hot Water System 

The addition of a polyurethane insulation layer is used for hot water storage in solar thermal collectors and air source heat pump systems to maintain stable water temperature and reduce heat loss, making it suitable for hot water supply in hotels, swimming pools, and bath centers.

5. Agriculture and Animal Husbandry 

It can be used for irrigation and water storage in farmland, and for drinking water storage in livestock farms. When installed outdoors, it can be fitted with a rainproof and sunproof shed. It can withstand humid outdoor environments and has a long service life.

6. Special application scenarios 

Seawater desalination and storage in coastal high-salt fog areas, purified water storage in the pharmaceutical industry, and temporary storage of raw materials in food processing are all made of 316 stainless steel, which is corrosion-resistant, easy to clean, and meets industry hygiene standards.

1. Initial water injection 

Clean the tank → close the drain valve, open the inlet valve and vent valve → slowly fill the tank with water using an external water pump to 90% of the rated capacity → close the valve and let it stand for 2-4 hours to check for leaks.

2. Routine inspection 

Maintain water level between 50% and 90%; check for deformation of the tank body, weld cracks, and aging of sealing strips weekly; calibrate the automatic liquid level control device monthly.

3. Drainage cleaning 

Empty and flush out wastewater every 3-6 months to remove sediment; clean food/medical water tanks monthly; completely empty tanks during winter shutdown to prevent freezing.

4. Ancillary equipment (optional) 

Heat preservation and heat tracing: turn on at low temperature (5-10℃), turn off when heating up; Disinfection device: turn on the drinking water tank for 30-60 minutes daily.

5. Safety Precautions 

Climbing is prohibited; warning signs should be set up for maintenance and two people should operate the equipment; keep away from open flames.
