Hot Dip Galvanized Water Tank
Hot Dip Galvanized Water Tank Structure
Water Tank Performance
Core materials and technical advantages
High strength and durability
The Q235 steel plate is treated by hot-dip galvanizing process to form a dense galvanized layer on the surface, which significantly improves corrosion resistance and can last for more than 15 years.
The compression molding process enhances the strength of the plate, and its pressure bearing capacity is better than that of traditional water tanks. It has strong seismic and impact resistance and is suitable for high-rise buildings and earthquake-prone areas.
Water quality safety guarantee
Good sealing, avoiding the breeding of algae and red worms, eliminating secondary water pollution, and meeting the sanitary standards for domestic water and fire water storage.
The hot-dip galvanized layer is smooth and easy to clean, suitable for scenes with high water quality requirements (such as hotel hot water and food industry).
Resistant to extreme environments
Excellent acid and alkali resistance, can store corrosive media such as industrial wastewater and pesticide ratio liquid.
A wide range of applicable temperature (cold water to 100℃ hot water), meeting high temperature requirements such as boiler water and solar heat storage.
Function and scope of application
Flexible customization and installation
Supports non-standard size customization, with a capacity of 1-2000 cubic meters and a height of up to 5 meters, adapting to different space requirements (such as underground, roof, and basement).
Modular assembly design, convenient on-site assembly, no welding equipment required, and short construction period (saving more than 50% time compared to concrete water tanks).
Multi-scenario adaptation capability
Construction engineering: Fire water tanks meet the specifications, have strong pressure resistance, and are suitable for high-rise fire water storage.
Industrial field: High temperature resistance and corrosion resistance meet the acid and alkali liquid storage needs of chemical plants.
Municipal and agriculture: Lightweight design reduces building loads and is suitable for rural irrigation and rainwater recycling systems.
User experience and cost advantages
Low maintenance and long-term benefits
Maintenance-free design, no leakage, no deformation problems, and long-term use costs are lower than concrete water tanks.
Hot-dip galvanizing process reduces the risk of rust and avoids the trouble of regular anti-rust paint for traditional steel plate water tanks.
Energy saving and environmental protection
The galvanized layer reflects heat, reduces heat loss, and is suitable for solar thermal storage systems.
The material is recyclable and meets green building standards
Hot Dip Galvanized 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: Hot dip galvanized sheet, 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.
