Abstract (en)
[origin: US2008216317A1] An improved method of producing radiators, for heating plants, comprising a vertical tube ( 1 ) affording holes ( 11 ) in which bushings ( 2 ) house, the bushings ( 2 ) being provided with O-rings ( 4 ) inserted in recesses ( 21, 23 a) afforded therein. The method comprises an expanding element provided with a internal stem ( 41 ) and an external expandable tubular element ( 42 ) exhibiting longitudinal flutes ( 421 ) which enable the external tubular element ( 42 ) to expand when the stem ( 41 ) is moved axially internally of the tubular element ( 42 ), a terminal slim tract ( 24 ) of the bushing ( 2 ) being thus enlarged and belling out to strike against walls of the holes ( 11 ). The bushing ( 2 ) is then unremovably inserted into a horizontal tube ( 3 ), a washer (R) inserted on the bushing ( 2 ) being crushed between an internal wall of the horizontal tube ( 3 ) and the bushing ( 2 ), eliminating possibility of sliding of the horizontal tube ( 3 ) away from the bushing ( 2 ), the bushing ( 2 ) and the horizontal tube ( 3 ) forming a ladder-type structure for a towel-warming type radiator.
