Cangzhou Bohai Steel Pipe Co., Ltd. production and supply elbow, and cheap. Stamping elbow, welding elbow (elbow butt) and so on. 16mn elbow first selected size, tube material made, for example, of 90 ° elbow, through which the curvature can be calculated how long the material can be processed at a bend of 90 °, then the length of cut length. Finally, the expected heat to push the system. Pushing machine is a horn-shaped core head or mandrel, the mandrel by thin thicken, pushing the system process is a process of expanding the band bending, behind a support, the lower section of the feed tube mandrel penetration, there is an arch frame behind the fixed mandrel, the middle of a car, the car and some by hydraulic transmission, some by mechanical transmission that screw drive, and then push the car forward, pushing the car along the mandrel tube to move forward, there is an induction coil outside the mandrel , the tube heats up well, and then push the car down the tube, it is a good process. After a good push, shaping the next bend to be this hot state, because some elbow treated properly, it will distort the price of steel elbow, which is not allowed. Another production of alloy steel elbow, usually after Tuitou outer diameter of the front, to be shaped by plastic molding. Plastic mold is actually a press, to have a mold, two semi-circular, up and down each one. After shaping the outer diameter of the finished size is reached. Here were the finishing process, after shot peening, the inner and outer surfaces of the oxide scale removal elbow to make the groove in order to deal with both ends of the weld. Then after checking, 15CrMo alloy steel elbow hit the word, spray paint, and packaging processes, you can factory up. Cangzhou Bohai Steel Tube Co., Ltd. specializes in the elbow called 16Mn high strength low alloy steel structure knot 16Mn high strength low alloy structural steel: carbon content of 0.1% -0.25%, to join the main alloying elements manganese, silicon, vanadium, niobium and titanium and so on. No signs 16Mn old country will now be classified as a low-alloy high-strength structural steel alloy steel elbow, now called grade Q345, Q345 steel but is 12MnV old number, a number of steel 14MnNb, 18Nb, 16MnRE, 16Mn, etc. kind of alternative, and not a substitute only 16Mn steel material. 16Mn alloy steel elbow, Cangzhou Bohai (certified), alloy steel elbow Ltd provided by Cangzhou Bohai fittings.
