The raw material is rolled seamless round tube, tube embryos subjected to cutting a length of about 1 meter cutter blank, and by the conveyor belt to the furnace heating. The billet is fed in the heating furnace, a temperature of about 1200 degrees Celsius. Fuel for hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube came out to go through the pressure punching machine wear empty. Generally more common punch is tapered roller punching machine, high production efficiency of this puncher 316l stainless steel pipe, product quality, perforated expanding capacity, can be worn a variety of steels. After perforation, round tube has been three-roll rolling, rolling or extrusion. To take off the tube after extrusion sizing. Sizing machine rotating at high speed into the embryo through a tapered drill steel perforated to form the pipe. Pipe inner diameter is determined by the outer diameter sizing mill drill length. After sizing pipe after entering the cooling tower, cooling by water stainless steel pipe, steel pipe, after cooling, it will be straightened. After straightening steel belt sent by metal detection machine (or hydrostatic test) for internal testing. If there is a crack pipe inside a stainless steel tube, bubbles and other issues, will be detected. After the pipe through strict quality control but also the selection of hand. After the pipe inspection, spray paint on number, size, batch number and so on. By a crane into the warehouse in 304 stainless steel pipe classification there are many, the first is seamless and straight seam welded 304 stainless steel tube, followed by basic classification structure 304 stainless steel pipes and industrial fluid transport 304 stainless steel tube. There is a division of the national standard, Japanese standard, American Standard and the like. Steel numbers and representation ① chemical element with the symbol of international and national symbols to represent the chemical composition, using the Arabic alphabet to represent the content: such as: China, Russia 12CrNi3A ② with a fixed number of digits to represent the steel type series or digital; as : The United States, Japan, 300 series, 400 series, 200 series; ③ with the Latin alphabet and numbers sequence composition, use only that Our professional agents 201.304 stainless steel decorative tube.
