Introduction
Welding Water Tank is a water storage device that uses welding technology to connect metal plates into an integral structure. It is widely used in industrial, civil and commercial fields. Common welded water tank materials include stainless steel, carbon steel and galvanized steel plates. They have strong sealing and durability and can be used to store domestic water, fire water, industrial cooling water, etc.
Advantages
Good sealing performance
The welded water tank adopts a full welding process, and the plates are welded to form an integral structure. Compared with the assembled water tank connected by bolts or sealing strips, the welded water tank eliminates the gaps that may occur at the connection parts, greatly reducing the risk of leakage. This structure enables the welded water tank to maintain good sealing in long-term use, and is suitable for occasions that require high sealing, such as fire water tanks or industrial water storage equipment.
Strong corrosion resistance
The welded water tank uses high-quality stainless steel (such as SUS304, SUS316) or galvanized steel plates and other materials. It has strong anti-oxidation and anti-corrosion capabilities and can resist the erosion of air, water and some chemicals. Especially in occasions such as food processing and pharmaceutical industries that have high requirements for water quality, the use of stainless steel welded water tanks can effectively ensure water quality safety and prevent secondary pollution.
High temperature resistance
Since the welded water tank adopts rigid connection, no additional sealing strips or fasteners are required, so it can maintain stable operation even under special working conditions such as high temperature, low temperature or high pressure, and is not easy to deform or leak due to temperature changes or pressure fluctuations. Therefore, welded water tanks are widely used in boiler water supply systems, chemical liquid storage systems, and other industrial environments involving high temperature or high pressure.
How to maintain
1. Regular cleaning
The water tank should be thoroughly cleaned every 6 to 12 months to remove scale, sediment and microbial growth to prevent secondary pollution of the water quality. Food-grade disinfectants can be used for cleaning, and strong acid and alkali cleaning agents should be avoided to prevent corrosion of the inner wall of the water tank.
2. Check the welds and anti-corrosion layer
Regularly check whether the welds of the water tank are cracked, rusted or leaking, especially for water tanks that are subjected to high pressure or temperature changes for a long time. If the inner wall of the water tank has an anti-corrosion coating, check whether it is falling off, bubbling or damaged, and repair it in time if necessary to extend the service life.
3. Check the water inlet and outlet
Regularly check whether the water inlet, outlet, overflow pipe and drain pipe are unobstructed to prevent overflow or poor drainage of the water tank due to blockage. If the water tank is not used for a long time, the internal water should be emptied to prevent bacterial growth or damage to the water tank caused by freezing in winter.
4. Take winter antifreeze measures
If the water tank is located in a cold area, insulation measures should be taken, such as installing an external insulation layer or electric heating system to prevent ice from forming inside the water tank and causing weld cracks. For water tanks that have been idle for a long time, the water should be drained in winter to prevent damage to the tank structure due to ice expansion.

Q: Can welded water tanks be used for drinking water storage?
A: It depends on the material selection. If food-grade SUS304 or SUS316 stainless steel is used, and it undergoes strict welding process and non-toxic anti-corrosion treatment, it can be safely used for drinking water storage. Carbon steel or galvanized steel welded water tanks are generally not suitable for drinking water.
Q: Compared with welded water tanks and assembled water tanks, which one is better?
A: Welded water tanks have better sealing and higher strength, and are suitable for high pressure and long-term water storage occasions; assembled water tanks are easy to transport and install, and are suitable for projects with space constraints. Which type to choose depends on actual needs.
Q: What are the welding methods for welded water tanks?
A: Common welding methods include argon arc welding (TIG), arc welding (MMA), submerged arc welding (SAW), etc. Argon arc welding is often used for stainless steel water tanks, and the welds are smooth, beautiful, and have good sealing.
Q: Do the welds of welded water tanks need to be polished?
A: Yes. Welds should be polished to remove welding slag and burrs, improve corrosion resistance, and reduce the possibility of scale and impurities adhering, especially in industries with high hygiene standards such as food and medicine.
Q: Can welded water tanks withstand high-temperature liquid storage?
A: It depends on the material. Stainless steel welded water tanks (such as SUS304, SUS316) have good heat resistance and can be used for hot water storage within a certain temperature range. However, long-term storage of high-temperature water in carbon steel welded water tanks may accelerate corrosion.
Q: Does the welded water tank need anti-corrosion treatment?
A: It depends on the material. Stainless steel welded water tanks usually do not require additional anti-corrosion treatment, while carbon steel welded water tanks usually require anti-corrosion measures such as galvanizing, epoxy coating or plastic lining to extend their service life.
Q: What specifications can welded water tanks be customized?
A: Welded water tanks can be customized in size, shape (rectangular, round, special-shaped), wall thickness, inlet and outlet size, overflow and drain outlet location, etc. according to user needs.
Q: What is the pressure bearing capacity of welded water tanks?
A: Welded water tanks are generally used for normal pressure or low pressure water storage because of their stable overall structure and strong pressure bearing capacity. However, if they need to withstand higher pressure (such as boiler water supply system), special design is required to thicken the plate and strengthen the weld structure.
Q: Will the weight of the welded water tank affect the load-bearing capacity of the building?
A: This needs to be considered during the design stage. The weight of the welded water tank after it is full of water is large, and the structural engineer should evaluate whether the installation location can withstand the load. If necessary, the load-bearing support structure needs to be added.
Q: Can welded water tanks be used for chemical liquid storage?
A: It depends on the type of liquid. Stainless steel welded water tanks are resistant to weak acids and alkalis, but for strong acids and alkalis or highly corrosive chemicals, special corrosion-resistant materials (such as 316L stainless steel or plastic lining anti-corrosion treatment) need to be selected.
Q: How to prevent blockage of the inlet and outlet of the welded water tank?
A: A filter device should be installed at the water inlet to prevent impurities from entering the water tank. Check the drainage system regularly to prevent blockage caused by sediment deposition. Use appropriate pipe interfaces to prevent pipe pressure from affecting the smoothness of water inlet and outlet of the water tank.
