A Method For Manufacturing Extended Back Pass Floor Panels Used In High Pressure Steam Generators
Abstract: The present invention proposes a method for manufacturing extended back pass floor panels (5). The individual tubes (32) for the developed length of whole panel is bent individually in rotary bending machine for a predetermined inclination angle, and then to be tacked to form sub panels (33) with the bend centerlines aligned. After machine welding in straight portion (10), panel (34) is to be loaded to panel support stands (24) for manual finning and welding at the terminal portion (11) using straight flats and two dimensional shaped plates (35). Edge bar cutting at both panel ends shall be done using the edge bar cutting machine (15) as per predetermined dimension. The panel is then to be fed to CDF (12) for stress relieving heat treatment followed by gang bending to an angle of 90°. The panel (5) is then be positioned on the ground layout prepared as per the dimension to verify the geometrical correctness.
