Detailed Product Description: | Carbon steel seamless elbow, seamless stamping elbow, short radius elbow 45 degrees you still can not find good fitting to worry about it? ! ! If you worry I just want to say: Please contact me! ! ! Sales Manager: Wang welcome to consult the National Order Tel :0311-68031627 15373637303 QQ: 2015693327 tee price, wholesale carbon steel elbow, pipe manufacturers, pipe plant Cangzhou En Ti 24-hour reception you soon seamless elbow pipe fittings in of pipe fittings industry has an important position. According to incomplete statistics, China's existing seamless elbow pipe approximately 240 manufacturing enterprises, seamless elbow pipe about 250 sets of units, with an annual capacity of about 4.5 million tons from the caliber of view, <φ76, accounting for 36%, <φ159-650, and accounted for 26% from the varieties, the general purpose of more than 190 million tons, accounting for 55%, oil pipe 770,000 tons, accounting for 6%, hydraulic prop, precision tubes 15 million tons, accounting for 4.5%, stainless steel stamping elbow pipe fittings, bearing tubes, automobile tubes total of five million tons, accounting for 1.5%. seamless elbow pipe manufacturing process because of different, is divided into hot-rolled (extrusion) seamless elbow pipe and cold drawn (rolled) seamless elbow pipe two kinds of cold drawn (rolled) pipe is divided into circular pipe and shaped pipe. now its simple process are described below: a. cold drawn (rolled ) seamless elbow pipe fittings: round tube perforation → → heating → → annealing → pickling → Heading oiled (copper) → multi-pass cold drawn (rolled) → billet tube → heat treatment → straightening → hydrostatic test (testing) → mark → storage cold drawn (rolled) seamless steel pipe rolling method than hot-rolled (extruded seamless elbow pipe) complex. Their first three steps of the production process is basically the same. differs from The fourth step begins, round tube through the gun empty, to begin with, annealing after annealing to use a special acidic pickling liquid. pickled, oiled and then followed through many times drawn (cold roll) and then blank tube, special heat treatment after heat treatment, will be straightening. pipe belt sent by straightening the metal detection machine (or water pressure test) for internal testing and if the internal pipe cracks, bubbles and other issues will be detected. pipe through strict quality control even after hand-selected. pipe inspection, the use of spray paint number, size, batch number, etc. into the warehouse by a crane hanging stainless steel stamping elbow is used with pipe of the same material as sheet metal stamping stamping die halves with annular elbow, then two half-rings welded elbow for group forming due to different types of pipe welding standards, which is usually fixed by group of semi-finished factory to the point, construction site welding of the pipe weld level, therefore, also known as the two halves welded elbow. stamping elbow by means of conventional or special processing equipment, power press, the plate material in the mold and be directly affected by the deformation of the deformation force, to obtain a certain shape, size, and performance parts of the production technology products. sheet metal, stamping dies and equipment are the three elements. punching processing is a processing method of metal cold deformation, so called cold stamping or sheet material stamping, punching short it is a metal plastic processing (or pressure processing) one of the main methods, also attached to material forming engineering stainless steel stamping stamping process using elbow with elbow tube outer diameter equal to, the use of pressure machine directly in the mold press forming. before stamping, tube placed in the lower mold, the inner core and the end of the mold into the tube, the upper die downward movement began repression by the constraints of the outer mold and die within a supporting role the elbow shaped stainless steel stamping elbow of cold stamping and hot stamping are two, usually based on material properties and the ability to choose equipment cold stamping or hot stamping. cold stamping elbow forming process is to use a dedicated elbow forming machine, the tube billet into the outer mold, the upper and lower mold clamping after putter, driven along the inner tube and the outer mold mold space reserved for the movement to complete the forming process shown in Figure 15-8 for a manufacturer of stainless steel elbow before extrusion and extrusion after photos. elbow by cold stamping die cold extrusion manufacturing process inside and outside of the elbow appearance, uniform thickness, size deviation is small, so especially for thin-walled stainless steel elbow stainless steel elbow forming multi-use of this process. This process uses high precision mold inside and outside of the tube wall thickness deviation of the more demanding requirements. |
