Stainless steel material into ordinary carbon steel, high-quality carbon steel, alloy pipe, steel pipe, bearing steel, stainless steel, and to save precious metals and meets bi-metal composite pipe, coatings and coated pipes and other special requirements . Many types of stainless steel pipes, stainless steel pipes for different purposes decoration, its technical requirements vary, production methods are also different. Pipe diameter range of current production 0.1-4500mm, wall thickness 0.01 ~ 250mm. To distinguish its characteristics, usually by the following method for steel classification. Production of stainless steel seamless pipe according to the mode of production and pipe into two categories, can be divided into hot-rolled seamless steel tubes, cold-rolled, cold drawn tubes and squeeze tubes, cold drawn, cold-rolled steel pipes secondary processing; Longitudinal and spiral welded pipe and so divided. Products according to national standard GB / T14976-2002 (fluid transport stainless steel seamless pipe), GB / T14975-2002 (structure seamless stainless steel), GB / T13296-91 (boiler, heat exchanger with stainless steel seamless pipe), decorative welded stainless steel pipe (GB / T 18705-2002), architectural decorative stainless steel welded pipe (JG / T 3030-1995), have to undergo rigorous testing, in line with national standards of technical requirements Material 321 / 1Cr18Ni9Ti 304 / 0Cr18Ni9 310S / 0Cr25Ni20 316L / 00Cr17Ni14Mo2 301 304L stainless steel is a long hollow circular steel, mainly used in petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial pipes and mechanical structural components. In addition, bending, torsional strength 316l stainless steel pipe, stainless steel pipe lighter, so it is widely used in the manufacture of mechanical parts and engineering structures. Also used in producing a variety of conventional weapons, stainless steel exports are an important part of China's export economy, its driving China's economic growth has an important role, however, from the current situation of China's foreign trade of stainless steel, the country's steel exports encountered a more large resistance.
