Cangzhou Bohai Pipe Co., Ltd. specializing in the production of 20 steel stamping elbow elbow with a certain degree of corrosion (oxidation acids, organic acids, cavitation), heat and wear resistance. Typically used in power plants, chemical, oil and other equipment and materials. Chromium stainless steel stamping elbow welding poor, should pay attention to the welding process, heat treatment conditions and choose the appropriate welding. Fifth, stamping elbow with titanium calcium type coating and low hydrogen type. Titanium calcium type can be used for AC and DC, but AC weld depth shallower 20 # carbon steel elbow, while easy redness, stainless steel stamping elbow so far as possible dc power supply. 20 carbon steel elbow should be used to keep dry sales 20 # carbon steel elbow, titanium calcium type should be dried 150 ℃ 1 hour should be dried with low hydrogen 200-250 ℃ 1 h (not repeated drying, or medicated skin peeling easy to crack), stainless steel stamping elbow coating prevents sticky oil and other dirt in order to avoid causing stainless steel stamping elbow weld carbon content increases the quality and impact of the weldment. Hebei Bohai Pipe Co., Ltd. specializing in the production of 20 carbon steel elbow. Buy 20 carbon steel elbow went to Hebei Bohai Sea. OK Principle 20 carbon steel elbow manufacturers bend the inner wall of the heating temperature is less than the principal stress yield limit of the material at this temperature austenitizing temperature or higher, and when you 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 parting comment following the impact of the technical parameters of the carbon steel elbow dash shape. Carbon steel elbow with the blank material, thickness and outer dash elbow to push the system the shape of the thermal occupation commonly bend pushing WB36 and A335P22 and other raw materials. Based on the plastic deformation of metal at constant volume, pushing molding constant wall thickness (practical micro-thinning), elbow and tube length of outer arc length characteristic flat deduced pushing the tube outer diameter of formula: where D --- elbow-sectional diameter; δ --- elbow thickness; R --- bend radius of curvature; Dp --- tube outside diameter. If the practice is smaller than the outer diameter of the tube chosen Dp value obtained by the formula calculation, and die bonding function better wholesale 20 # carbon steel elbow, but the arc in the elbow simply wrinkling. If the practice is larger than the outer diameter of the tube chosen Dp value obtained by the formula calculation, the results are the opposite happened. Based on the above criteria, for this experiment selected by pushing the elbow to push the system shell. Simulation medium is water at room temperature, Reynolds size: 0.498 × 105 ~ 4.98 × 105, and upstream research program comprises a single baseline Elbow 90 ° categories, a total of 15 groups using a uniform flow coefficient relative error and additional uncertainty as equipment condition. The primary assessment specification given length of straight pipe upstream of the single Elbow 90 °, and with foreign research findings were compared with carbon steel elbow usefulness and device use: small to large companies in each family bent steel. Head has its own interests and use marine 20 # carbon steel elbow, warmly welcome new and old friends to buy. carbon steel elbow pipe device is commonly used as a link with the elbow, for engaging the pipe at the corner Other titles: 90 degree elbow, right angle bend, bend and so love.
