Abstract

PURPOSE: To manufacture a very slender thin-walled tube having a large inside/ outside diameter ratio by heating a glass tube with one end sealed while applying a predetermined pressure to the interior of the tube and drawing the heated tube.
CONSTITUTION: One end of quartz matrix tube 1 is sealed, and while feeding a gas such as nitrogen in cylider 4 from the other end under 1W50mmH2O gauge pressure, tube 1 is heated with heater 3 and drawn to manufacture very slender tube (glass column) 2. By this method a reduction in the volume of the glass tube due to the surface tension of the molten glass is inhibited in drawing, and by regulating the pressure applied to the interior of tube 1, a slender tube having arbitrary inside and outside diameters can be formed easily from a uniform matrix tube.
