1. According to the requirements and surface conditions of stainless steel elbows, different methods such as alkaline cleaning, chlorine solvent sandblasting, water-soluble cleaning agent, shot blasting, etc. are used for cleaning.

2. When cleaning Stainless Steel Weld Elbow, pickling is generally not used for cleaning. Mastering the key points of cleaning stainless steel elbows can improve their safety performance and extend their service life. The welding rod must be kept dry at all times during use. The titanium calcium 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 many times, otherwise the skin will easily crack and peel off. Prevent the welding rod skin from sticking oil, so as not to increase the carbon content of the weld and affect the quality of the weldment. When welding stainless steel elbows, if they are repeatedly heated, carbides will precipitate, which will reduce their corrosion resistance and mechanical properties.
