The petrochemical industry involves corrosive fluids such as acids, alkalis, and salts. Stainless steel pipes have the characteristics of corrosion resistance and oxidation resistance. In the petrochemical industry, stainless steel pipes are mainly used in pipeline transportation systems, including high-pressure furnace tubes, piping, petroleum cracking tubes, fluid transportation pipes, heat exchange tubes, etc. At the same time, in the equipment manufacturing, oil extraction, refining and other aspects of the petrochemical industry, stainless steel pipes play an important role. Stainless steel is required to perform well in wet and acidic service conditions.
