| First, the thicker the wall thickness of the product, it becomes an economic and practical, the thinner wall thickness, it will greatly increase processing costs; Secondly, the product of the process to ***ermine its limitations, the general low precision seamless steel pipe: uneven thickness, the tube surface brightness is low, the high cost of fixed length, and there are pits in appearance, difficult to remove black spots; Third, it must be off-line ***ection and plastic processing. Therefore it is high pressure, high strength, mechanical aspects of structural material reflects its superiority. Stainless steel tube type: sub-rolling method then rolled, hot extruded and cold drawn (rolled) stainless steel tube. By stainless steel microstructure of ferrite and a half different half-Markov system, stainless steel, martensitic stainless steel, austenitic stainless steel pipes, austenitic - ferritic stainless steels tubes. Stainless steel tubes and appearance quality: £¨1£© according to GB14975-94 "stainless steel seamless pipe," provides that the length of pipe is usually (not length) hot-rolled steel 1.5 ~ 10m, hot extruded pipe is equal to and greater than 1m. Cold drawn (rolled) pipe wall thickness 0.5 ~ 1.0mm were, 1.0 ~ 7m; wall thickness greater than 1.0mm were, 1.5 ~ 8m.£¨2£©, hot-rolled (hot extrusion) and the diameter 54 ~ 480mm total of 45 species; wall thickness of 4.5 ~ 45mm A total of 36 species. Cold drawn (rolled) and the diameter 6 ~ 200mm total of 65 species; wall thickness of 0.5 ~ 21mm total of 39 species. £¨3£© steel inner and outer surface shall not crack, fold, crack, crack, rolled off, there is separation and scarring defects, these defects should be completely removed (except for tube machining), cleared the wall and not outside diameter than the negative deviation. Which do not exceed the allowable negative deviation of the other minor surface defects do not cleared. £¨4£© straight to allow depth. Hot-rolled, hot extruded steel tube, 140mm in diameter and is equal to not more than 5% of the |
