Hebei Bohai Tube Co., Ltd. specializes in producing carbon steel elbow 20. Buy 20 carbon steel elbow went to Hebei Bohai Sea. Carbon steel elbow 20 specification, the principles of determining the heating temperature of the carbon steel elbow bend of the inner wall of the principal compressive stress is less than the yield limit of the material at this temperature austenitizing temperature or higher, and when the push system. Material austenitizing temperature, the higher the heating temperature; yield limit of the material temperature, the higher the heating temperature. Induction heating, the maximum temperature WB36 steel is 850 ~ 900 ℃ factory 20 # carbon steel elbow, A335P22 steel is 900 ~ 950 ℃, the heating temperature is the highest point A335P91 material for 900 ~ 1000 ℃. Temperature measurement methods for fixed and manual far-infrared thermometer combines far-infrared thermometer. Temperature distribution is an important process parameters, by the induction coil and the induction coil shape and relative position of the direct control of the mandrel head. Induction loop shape is a major factor, the induction coil and the relative position of the mandrel head is a secondary factor. Radial temperature distribution along the mandrel head low, medium and high. Heating temperature is high, the wall thickness increases stamping elbow. Hebei Bohai Tube Co., Ltd. specializes in producing carbon steel elbow 20. Buy 20 carbon steel elbow went to Hebei Bohai Sea. 20 carbon steel elbow bend radius specifications on (R): R = 3D, 4D5D6D ,,, 7d, 8D, 9D, 10D. Bending angle (θ): 15O, 30,45,60o, 90o, 135 and 180 degrees 20 # carbon steel elbow four times, you can also give the manufacturer according to the customer's perspective. An outer diameter (D): D≤1800mm wall thickness (T): T≤120mm groove: According pipe groove welding construction Weight: weight (kg) = [0.0433 (DT) TRθ] / 100000 + L (ends curved straight weight) is used to change the bending direction pipe.it advantage is that you can run long distances matach transfer requirements, so it is usually bent, size can be designed according to customer requirements. Usually offer 20 # carbon steel elbow, bend, including 3d, 5d, 7d or 12d. 20 # carbon steel elbow, Cangzhou Bohai, short radius 20 # carbon steel elbow pipe fittings provided by Cangzhou Bohai Limited.
