When cleaning the sanitary ball valve, we need to pay attention to the following two aspects: 1. According to the requirements of the sanitary valve and the surface condition, use different methods such as alkaline cleaning, chlorine solvent sandblasting, water-soluble cleaning agent, shot blasting, etc.; stainless steel elbow 2. When cleaning the sanitary ball valve, the pickling method is generally not used for cleaning. Mastering the key points of cleaning stainless steel ball valves can improve its safety performance and extend its service life. Welding rods should be kept dry at all times during use. The calcium-titanium type should be dried at 150°C for 1 hour, and the low-hydrogen type should be dried at 200-250°C for 1 hour. Be careful not to repeat the drying, otherwise the skin will easily crack and peel. Prevent the electrode skin from sticking to oil, so as not to increase the carbon content of the weld and affect the quality of the weldment. When the sanitary ball valve is installed, if it is repeatedly heated, carbides will be precipitated, which will reduce its corrosion resistance and mechanical properties.
