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)。


無縫鋼(gang)管是用(yong)擠型或是輥式穿(chuan)孔方(fang)式+冷軋或冷拔相結(jie)合制造。


焊(han)(han)接或電(dian)阻焊(han)(han)接管(Electric resistance welding)是將金屬片(pian)折彎成管狀后(hou),在(zai)邊(bian)緣部(bu)分(fen)焊(han)(han)接接合,因此在(zai)管的側面會(hui)有焊(han)(han)接縫(feng)。
