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(gang)管(guan)是(shi)用擠型(xing)或是(shi)輥(gun)式穿孔(kong)方(fang)式+冷軋或冷拔相結合制(zhi)造。


焊(han)(han)(han)(han)接(jie)或電阻焊(han)(han)(han)(han)接(jie)管(Electric resistance welding)是將金屬(shu)片折(zhe)彎成管狀(zhuang)后(hou),在邊緣部(bu)分焊(han)(han)(han)(han)接(jie)接(jie)合(he),因此在管的側(ce)面(mian)會有焊(han)(han)(han)(han)接(jie)縫。
