Title
(EN) Glass tube production method
(ZH) 玻璃管的制造方法
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.
(ZH) 一种玻璃管(11)的制造方法,具备如下工序:在玻璃管(16)的第1端(16a)侧的管壁形成贯穿孔(15);以及在形成贯穿孔(15)后,通过对从玻璃管(16)的第1端(16a)到贯穿孔(15)为止的预定部位进行热加工,从而形成密封部(13)。
