Hebei Bohai Tube Co., Ltd. specializes in producing carbon steel elbow 20. Buy 20 carbon steel elbow went to Hebei Bohai Sea. Principle 20 carbon steel elbow to determine the manufacturer of the heating temperature is less than the elbow inner wall of the main stress in the material yield strength of the material at this temperature austenitizing temperature or higher, and when to push the system. Material austenitizing temperature, the higher the heating temperature; yield limit of the material temperature, the higher the heating temperature. 20 carbon steel elbow manufacturers technical parameters of information leave a comment below influence of the technical parameters of the carbon steel elbow dash shape. Carbon steel elbow with a blank material, thickness and outer dash right elbow to push the shape of the thermal occupation of the raw material used to push the system elbow A335P22 have WB36 and so on. Based on the volume of the plastic deformation of metal at the same, pushing molding constant wall thickness (micro thinning practice), elbow outside the arc length and flat tube length features, the outside diameter of the tube to push the system to derive the formula: where D --- elbow-sectional diameter; δ --- elbow wall thickness; R --- bend radius of curvature; Dp --- tube outer diameter. If the practice is smaller than the outside diameter of the tube selected according to a formula accounting Dp values ??obtained with the mold fit function is good, but in the elbow arc simple wrinkling. If the practice of selected tube diameter ratio Dp value calculation formula obtained by large national standard 20 # carbon steel elbow, the results are the opposite happened. Based on the above criteria 20 # carbon steel elbow, for this experiment with the elbow to push the system to push the system chosen tube. Simulation medium is water at room temperature, Reynolds size: 0.498 × 105 ~ 4.98 × 105, and the upper reaches of the baseline research program comprises a single 90 ° elbow into two categories, a total of 15 groups using uniform discharge coefficient relative error and additional uncertainty as the device condition. The primary assessment specification given length of straight pipe upstream of a single 90 ° elbow, and with foreign research findings were compared with the use of carbon steel elbow with device use: small to large companies in each family bent steel. Head has its own interests and usefulness, warmly welcome new and old friends come to buy carbon steel elbow pipe device is commonly used as a link with the elbow bend pipe for convergence of other titles: 90 degree bend head, right angle bend, bend, etc. love. 1. The manufacturing process can be divided into push the system, pressing, forging, casting and so on. 2. manufacturing standards can be divided into GB, electricity standard, ship standard, technology standard, water standard, American standard elbow, German standard, Japanese standard, the Russian standard and so on. 3. It's the radius of curvature of points: can be divided into long radius elbows and short radius elbows. Long radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the tube, ie R = 1.5D; short radius elbow refers to its radius of curvature equal to the pipe diameter Marine 20 # carbon steel elbow, namely R = 1.0D . Seamless carbon steel elbow in the process should pay attention to the problem of determining the principles of carbon steel elbow heating temperature is above austenitizing temperature material and the inner wall of the elbow to push the system when the main stress is less than the material at this temperature, the yield limit. Material austenitizing higher the temperature, the higher the heating temperature; material yield higher temperature limit, the heating temperature, the higher carbon steel elbow GB 20 #, 20 # carbon steel elbow, Ltd.
