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(shi)用(yong)擠(ji)型或是(shi)輥(gun)式(shi)穿孔方(fang)式(shi)+冷(leng)軋或冷(leng)拔(ba)相結合制造。
焊接(jie)或(huo)電阻焊接(jie)管(Electric resistance welding)是將金屬(shu)片(pian)折彎(wan)成管狀后,在邊(bian)緣(yuan)部分焊接(jie)接(jie)合,因此(ci)在管的側面(mian)會(hui)有焊接(jie)縫。
