目前不銹鋼管有兩種制造管子的方式:無縫鋼管(seamless)、焊接或是電阻焊接(electric resistance welding,ERW)。


無縫(feng)鋼管是用擠型或是輥(gun)式(shi)穿孔方(fang)式(shi)+冷軋或冷拔(ba)相結合制(zhi)造。


焊(han)(han)接(jie)或電阻焊(han)(han)接(jie)管(guan)(Electric resistance welding)是將金屬片折彎成管(guan)狀后,在邊緣部分焊(han)(han)接(jie)接(jie)合(he),因此在管(guan)的側面(mian)會有(you)焊(han)(han)接(jie)縫(feng)。
