[0002] Compared with other water tanks, stainless steel water tank has many advantages, such as beautiful appearance, light weight, high strength, corrosion resistance, high temperature resistance, clean water quality, anti-seepage, shock resistance, never moss, no secondary pollution of water quality, easy installation, no maintenance, easy to clean and so on. The welds on the traditional stainless steel water tank have a high risk of aging during long-term use. The outside of the water tank is damaged, causing the internal layer to come into contact with the outside world, which can accelerate the corrosion of the internal oxidizable part and reduce the service life of the product.

[0003] After searching, a new type of anti-corrosion square stainless steel water tank with welds is disclosed in Chinese utility model patent (publication number CN212244696U). The number of tanks to be installed can be adjusted according to actual needs to adjust the overall capacity of the water tank. The corrosion-resistant coating inside the tank improves the corrosion resistance. A waterproof layer is added to the weld to improve the sealing performance. The tank exterior is manually treated with wire drawing to improve the wear resistance. The inlet and outlet are provided with detachable filter screens, which not only reduce the amount of impurities entering the tank and maintain stable water quality, but also facilitate cleaning of the filter screen.

[0005] After the adjacent tanks are welded and connected, only the joints on the outside of the tank are welded and coated with a waterproof layer, which leaves small gaps inside the inside joints of the tank. Water can easily seep into the gaps during use, forming a long-term humid and oxygen-deficient closed environment, which can easily induce crevice corrosion. Even if the inside joints are welded, if effective protective measures are not taken, the weld heat-affected zone may still form corrosion weak points due to changes in the microstructure, residual surface oxidation scale and other problems, leading to pitting corrosion, stress corrosion and other local damage, affecting the sealing performance and structural reliability of the water tank.
