Title
(DE) VERFAHREN ZUR HERSTELLUNG VON GLASROHREN
(EN) GLASS TUBE PRODUCTION METHOD
(FR) PROCÉDÉ DE PRODUCTION D'UN TUBE EN VERRE
Abstract
(EN) A production method for glass tubes (11), comprising: a step in which a through-hole (15) is formed in a tube wall on a first end (16a) side of a glass tube (16); and a step in which, after the through-hole (15) has been formed, a sealed section (13) is formed as a result of a prescribed location from the first end (16a) of the glass tube (16) to the through-hole (15) being heat-treated.
(FR) La présente invention concerne un procédé de production de tubes en verre (11), comprenant : une étape dans laquelle un trou traversant (15) est formé dans une paroi de tube sur un côté de première extrémité (16a) d'un tube en verre (16); et une étape dans laquelle, après que le trou traversant (15) a été formé, une section scellée (13) est formée suite au traitement thermique d'un emplacement prescrit situé entre la première extrémité (16a) du tube en verre (16) et le trou traversant (15).
