FIELD: technological processes; heating.
SUBSTANCE: inventions may be used in manufacture of units for unit-sectional devices for recovery of heat from gases exhausted by devices, which are intended, in particular for heating of air by exhaust combustion products that are supplied from gas pumping set gas turbine unit compressor at compressor stations of gas mains. Technological complex of equipment comprising technologically connected posts is used to manufacture bodies of heated air supply and drain headers, pipes, tube plates with openings for pipes, elements of heat exchanging unit frame, panel of tube medium displacer. Pipes are bent at pipe-bending equipment, frame of heat exchanging units and headers are installed, where tube plates are welded in. Multiple-row bundle of pipes are loaded with different pitch and are installed in device for storage of pipes.
EFFECT: higher efficiency of heat exchanging devices and their units manufacture.
