Claims

[Scope of utility model registration request]

It has an end plate connected to both sides of the mantle tube, and a plurality of support plates are arranged in the middle of the mantle tube, and a number of heat exchanger tubes are coaxially passed through holes in the support plate, and both ends thereof are connected to the end plate. In a shell-and-tube heat exchanger, an offset jig is placed around the outer periphery of the end of the jacket tube, and an offset bolt that presses the end plate is screwed into this jig. A multi-tube heat exchanger characterized in that an offset is performed after heat tubes are inserted.
