A double elbow, 1.5 times the elbow, two times the elbow, 2.5 times the elbow 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 Uses: Connecting two nominal the same or different diameter pipes, the pipes for the 90 °, 45 °, 180 ° and various degrees of turn. Bending radius less than or equal to 1.5 times the diameter of the elbow are greater than 1.5 times the diameter of pipe belongs. Carbon steel pipe elbow is to change the direction of the metal pipe fittings. Carbon steel elbow first by its radius of curvature 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 pipe diameter, i.e. R = 1.5D. Short radius elbow refers to its radius of curvature equal to the pipe diameter, ie R = 1.0D. (D is the diameter of the bend, R is the radius of curvature) to points if the pressure level at about seventeen species, and the U.S. standard tubes are the same, are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, which is the most commonly used two kinds of STD and XS. Press the elbow angle points, there are 45 ° elbow with 90 ° and 180 ° elbow bend. , Carbon steel can be divided into 10 # 20 # A3 Q235A 20g 20G 16Mn ASTM A234 ASTM A105 ASTM A403 and other raw materials used for the production of these materials can be called carbon steel elbow carbon steel elbow bend at angles of: 45 °, 90 °, 180 ° elbow three commonly used, and another project needs, such as may be specifically tailored and 60 °. Are linked with the carbon steel pipe: Welded, flanged, threaded, socket links and other forms. Process can be divided in accordance with the form: welding elbow, pressing elbow, cast elbow. Purpose: to connect two tubes at right angles to the tube may or direction of 45 °. Manufacturing standards: GB, American standard, Japanese standard, German standard, the Russian standard. Carbon steel elbow basic process is: First welding a polygonal cross-section or a polygonal ring shell closed at both ends of the multi-row fan shell, the internal pressure washed over the media, applying less pressure, internal pressure under cross-section gradually turned round by a polygon, eventually becoming a circular ring shells. If necessary, a circular ring shell can be cut four or six 90 ○ 60 ○ elbow elbow elbow or other specifications, the process for the manufacture of medium diameter elbow with elbow diameter ratio greater than 1.5 in any specification Large elbow, is ideal for manufacturing large carbon steel elbow method.
