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) 316l stainless steel pipe, tube 304 for some special stainless steel tube, to compensate for the impact strength of the thread on the pipe end, usually in front of the car to make the pipe ends thicker wire (inside thickened, outside or inside and outside the thick thick ). 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. 304 stainless steel has good cold and hot processing performance, can be common to a variety of hot and cold processing production forgings, rod, wire, sheet, strip and wire and other metallurgical products of stainless steel pipes, thermal processing temperature range of 900 -1180 ℃. Easier cold stainless steel, no special difficulties, because of two cold-hardened steel is easy, when excessive cold deformation required intermediate annealing treatment, in order to facilitate further processing.
