    Application

    Stainless steel seamless pipes are widely used in industrial transmission pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food processing, light industry, papermaking, ships, aircraft, mechanical instruments and so on. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in the production of various conventional weapons, barrel, shells…etc.
