Stainless - steel seamless steel pipe is a long - strip steel product with a hollow cross - section and no seams on the periphery. It is a steel pipe resistant to weak corrosive media such as air, steam, and water, as well as to chemical corrosive media such as acids, alkalis, and salts. It is also known as stainless acid - resistant steel pipe.
According to the rolling method, it can be divided into hot - rolled, hot - extruded, and cold - drawn (rolled) stainless - steel pipes.
According to different stainless - steel metallographic structures, it can be divided into semi - ferritic - semi - martensitic stainless - steel pipes, martensitic stainless - steel pipes, austenitic stainless - steel pipes, austenitic - ferritic stainless - steel pipes, etc.
