  1, blanking

  Plate thickness can be selected according to the thickness of the carbon steel elbow, t=2mm. According to the technical requirements of the carbon steel elbow, according to the promise to have a few seams to cut material, usually 90. Elbow can allow 3~4 seams, so the elbow can be divided into 3~4 sections to cut, to ensure smooth welding seam, each edge (weld) according to the plane unfolding curve blanking.

  2, roll bending

  Roll bending is carried out after cutting, and the bending radius is 1 / 2 of the Carbon Steel Elbow Forged Fitting, and the single curvature rolling is adopted in each section. Single rate r=5OOmm. When rolling, the straight edge should be taken as the datum to avoid roll deviation.

  3. Welding constitutes a closed ring shell

  The shell will roll by welding a closed ring welding on the shell, water inlet and water outlet in the loop closed shell, injection nozzle for liquid medium filled in the closed ring shell, and through a pressure system (pressure test pump) is applied in pressure to the closed shell, drain for pressure relief pressure. Under the effect of internal pressure, the shell produces plastic deformation and gradually tends to ideal shape
