Stainless steel pipe according to the pipe end state can be divided into light pipe and threading pipe (with steel pipe). Threading pipe threading pipe can be divided into ordinary (for conveying water, gas and other low-pressure pipe, using ordinary cylindrical or tapered pipe thread connection) and special threaded pipe (petroleum, geological drilling pipe, pipe threading for important, the use of Special threaded connection), for some special tube, to compensate for the impact strength of the threaded end of the tube, usually in front of the car wire to make the pipe end thickening (thickening inside, outside or inside and outside thickening thickening). Use classification by purpose can be divided into OCTG (Casing, tubing and drill pipe, etc.), line pipes, boiler tubes, mechanical structure tube, hydraulic prop tube, cylinder tube, geological pipe, chemical pipe (high pressure chemical fertilizer pipe, oil cracking tubes) and ships with tubes. Stainless steel tube is safe and reliable, environmental health, affordable stainless steel pipes, thin-walled pipes and new reliable, successful development of simple and convenient method of connecting to other pipes with more irreplaceable advantages will increasingly Engineering more use will become increasingly popular 316l stainless steel pipe, a good prospect. Since stainless steel materials already have many desirable properties required, it can be said that in the metal is unique, and its development continues. For the stainless steel in the traditional applications with better performance, has been the improvement of existing types of 310s stainless steel pipe, and, in order to meet the stringent requirements of advanced architectural applications, is developing new stainless steel. Due to the continuous improvement of productivity, quality, continuous improvement, stainless steel pipe has become the most cost-effective choice of material architects is a long hollow circular steel stainless 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, lighter weight, 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.
