  Stainless steel water tank The water inlet is usually connected from the outer wall, or from the bottom or top. When the insulation water tank leaks under the working pressure of the pipeline network, the water level control valve or floating ball switch of the hydraulic press shall be installed at the inlet and outlet of the water inlet as far as possible. The top of the pressure regulating valve is connected with the water storage tank. When the pipe diameter is ≥ 50 mm, the total number is generally no less than 2. Each pressure regulating valve shall be equipped with maintenance gate valve. The water level control valve should not be installed when the heat preservation water tank leaks water under the working pressure of the pressurized water pump by using the water level line elevator automatic control system.


The drain pipe of stainless steel water tank shall be connected from the bottom at least. The tap water pipe is equipped with screw or flange gate valve (stop valve is not allowed). The drain water pipe can be connected with the overflow water pipe, but can not be connected with the drainage equipment immediately. When there is no special requirement, the drain water pipe shall be no less than 50mm. In the water containing Cl -, the weak stage of corrosion of stainless steel water tank is the welding area. Due to the prohibition of high temperature heating, the mechanism and function are deteriorated, and the anti-corrosion effect is also reduced.

Therefore, the application life of the water storage tank mainly depends on whether the grain boundary corrosion, in-situ stress corrosion and point (GAP) corrosion can occur at the weak stage (welding area) of the water storage tank. The experimental discussion shows that crevice corrosion is the most common corrosion method in water storage tank when the concentration of Cl - ionization in water is high.


There are many types of stainless steel water tanks. The selection and introduction of the logo of stainless steel plate comprehensively considers the compressive strength, plastic deformation, welding weldability and rationality, which is the unique adhesion resistance in the salt water containing sulfate. 304 stainless steel plate, widely used in chemical plants, food industry production and kitchen equipment, belongs to austenitic stainless steel plate, with excellent compressive strength, plastic deformation and good welding performance. Nowadays, most of the non pressure water storage tanks in China are made of 304 stainless steel plate.
