FIELD: manufacture of heat-exchange equipment, applicable in machine building.
SUBSTANCE: the jig has a supporting frame with intermediate and end processing supports positioned in it in two rows for fixation respectively of side walls and gas input and output chambers installed at the ends of the section. Each processing support has horizontal supporting platforms, and at least part of the processing supports has posts mounted on them with at least one coordinate-pendulum section of the surface put out for the overall dimensions of the outer surface of the respective wall of the manufactured section. At least one end support on each end of the jig is provided with a upper coordinate fixing member, the contact surfaces of these members on the opposite ends of the jug are installed with a height difference making up 0.002 to 0.009 of the jig working length with no allowance made for the summary length of the coordinate-fixing members.
EFFECT: provided a high-accuracy assembly of the heat-exchange section with exclusion of violations of the geometric parameters of the relative position of all its members.
