Stainless Steel Water Tank
Stainless steel water tank is a kind of water storage equipment widely used in household, commercial and industrial fields. It is made of stainless steel material, which has the advantages of corrosion resistance, anti-aging, no leakage, clean water quality, etc., so it can maintain good performance in various environments.
Main features
Corrosion resistance: Stainless steel material itself has excellent corrosion resistance, which can effectively prevent the erosion of water tanks by chemicals in water.
High strength: Stainless steel material has high strength and can withstand greater pressure, ensuring the safety and stability of water tanks.
Hygiene and environmental protection: Stainless steel has a smooth surface and is not easy to breed bacteria and algae, ensuring clean and hygienic water quality, which is very suitable for storing drinking water.
Long life: Due to its material characteristics, stainless steel water tanks have a long service life and relatively low maintenance costs.
Beautiful and generous: The appearance is simple and generous, and different shapes and sizes can be customized according to needs, suitable for a variety of occasions.

Water Wank Board Performance
Core materials and technical advantages
Food-grade safety and hygiene
Using 304/316L stainless steel, it has passed the GB/T 17219 drinking water hygiene standard to prevent secondary water pollution. It is suitable for food processing, hospitals, hotels and other high-hygiene scenarios.
The surface is mirror-polished (optional Ra≤0.6μm), smooth and scale-free, inhibits bacterial growth, and has extremely low cleaning and maintenance costs.
Ultra-high strength and durability
It has excellent compression and seismic resistance and can withstand a pressure of ≥100kPa (2-3 times that of ordinary water tanks). It is suitable for high-rise building fire water tanks and elevated pressure water storage.
High temperature resistant (-200℃~800℃), suitable for high-temperature scenarios such as boiler water supply and solar heat storage, without deformation risk.
Corrosion resistance and long life
316L stainless steel has a 30% increase in resistance to chloride ion corrosion, and is suitable for corrosive environments such as coastal areas and chemical plant wastewater storage.
The service life is more than 30 years, far exceeding galvanized steel plates (10-15 years) and fiberglass water tanks (20 years).
Function and scenario adaptation
Full scenario coverage
Construction engineering: The high-pressure design meets the GB50016 fire protection specification and supports fire water storage in high-rise buildings.
Municipal water supply: Large assembled water tanks (1000 tons +) are adapted to urban water supply peak regulation and rainwater recycling systems.
Commercial projects: Customized arc/special-shaped water tanks are perfectly integrated into the roof design of hotels and shopping malls, and run silently without disturbing residents.
Industrial field: Acid and alkali resistance and high temperature resistance meet the special liquid storage needs of electroplating plants and chemical plants.
Flexible customization and intelligence
Support non-standard sizes (diameter, height, interface position), capacity (1-5000 tons)
Stainless Steel Water Tank Installation Steps
Site confirmation
Ensure that the installation site is flat and solid to avoid ground subsidence or tilt.
Reserve enough operating space (generally leave more than 50cm of space around for later maintenance).
If the water tank is installed on the roof, it is necessary to confirm that the roof's load-bearing capacity meets the requirements.
Foundation production
Concrete foundation:
Cast concrete foundation (C20 or above), thickness ≥20cm, surface level (error ≤3mm/m²).
The foundation size should be slightly larger than the bottom plate size of the water tank (10-15cm wider on each side).
Channel steel foundation (suitable for large-capacity water tanks or special sites):
Use hot-dip galvanized channel steel to weld into a grid-shaped bracket, with a grid spacing of ≤50cm×50cm to ensure overall levelness.
Tools and material preparation
Tools: lifting equipment (such as forklifts, cranes), rubber hammers, spirit levels, wrenches, sealant guns, etc.
Materials: Stainless steel water tank plate, sealants (food-grade silicone), bolts, flange interfaces, etc.
1. Installation of bottom plate
Lay the bottom plate flat on the foundation, check whether it is level, and adjust it to an error of ≤2mm.
The bottom plates are connected by bolts, and sealant is applied to the joints (both inside and outside are required).
After installation, let it stand for 24 hours for the sealant to cure.
2. Installation of side plates
Assemble the side plates according to the order of the water tank design drawings, starting from the bottom layer and splicing upward layer by layer.
Fix each side plate with bolts, and tighten the bolts evenly (avoid deformation caused by local overtightening).
Sealant is also applied to the joints to ensure no gaps.
For each layer of side plates installed, the verticality needs to be corrected with a level (error ≤5mm).
3. Installation of top plate
The top plate and side plates are connected by bolts, and the joints are sealed.
4. Installation of accessories
Inlet and outlet: Install the flange interface according to the design position to avoid uneven force when connecting the pipes.
Overflow pipe, sewage pipe: The installation height meets the design requirements, and the overflow pipe must be higher than the highest water level.
Ladder and manhole: install in a reasonable location to ensure safe maintenance.
