This utility model relates to the technical field of temperature control equipment for pipe forming, and more particularly to a forming device for zoned temperature control of large-diameter thin-walled low-thermal-expansion pipes based on sodium-cooled fast reactors. The device includes: a forming mold, multiple first temperature control units, and multiple second temperature control units. The first and second temperature control units are evenly spaced along the axial direction of the forming mold, and are arranged opposite to each other. The first temperature control units are embedded in the outer wall of the forming mold, and the second temperature control units are embedded in the inner wall of the forming mold. During the forming of the large-diameter thin-walled low-thermal-expansion pipe, the heat generated by the first temperature control units acts on the outer wall area of ​​the large-diameter thin-walled low-thermal-expansion pipe, and the heat generated by the second temperature control units acts on the inner wall area of ​​the large-diameter thin-walled low-thermal-expansion pipe. This utility model, through zoned temperature control of the inner and outer walls, can reduce the temperature difference between the inner and outer surfaces of the large-diameter thin-walled low-thermal-expansion pipe, thereby improving the forming effect of the large-diameter thin-walled low-thermal-expansion pipe.
