  • Basic Forming Process of Carbon Steel Elbow
    May. 28, 2018

    Carbon steel elbow without tube billet as raw material, can cut down the cost of pipe equipment and mould, and can get any large diameter and wall thickness is relatively thin elbow can shorten the manufacturing cycle, the production cost greatly reduced. Because no special equipment is needed, it is especially suitable for large bending head on site. The technology has been declared a national invention patent. The blank is flat or developable surface, which makes the blanking simple, accurate and easy to assemble and weld.

    Carbon steel elbow basic process is: first, welding a cross section of a polygon or both ends closed multi multi ring shell fan shell, internal filled with medium pressure, with inner pressure and internal pressure under the action of cross section of polygonal gradually became round, and eventually become a circular ring shell. According to the need of a circular ring shell can be cut into four 90 ° bend or six 60 ° elbow or other specifications of the elbow, the process is suitable for manufacturing elbow pitch diameter and any specifications of large elbow bend diameter ratio greater than 1.5, is the ideal way to make the large carbon steel elbow.

    Low carbon steel with good plasticity and low strength, add the right amount of carbon elements will become hard, plasticity reduced strength. Flange connection may need to withstand high tensile, compression, torsion, shear strength, carbon steel flange is a good choice. Generally used in pipes, in that case, loose bolts can rotate both sides of the pipes, and then tighten them can be more convenient to remove the pipes.
