出(chu)產(chan)辦法

鋼(gang)管(guan)(guan)分為(wei) 無縫鋼(gang)管(guan)(guan)和(he)焊(han)(han)接鋼(gang)管(guan)(guan)。無縫鋼(gang)管(guan)(guan)生 產(chan)進程是將實心(xin)(xin)管(guan)(guan)坯或(huo)鋼(gang)錠穿成(cheng)(cheng)空 心(xin)(xin)的(de)毛管(guan)(guan)，然后再將其軋(ya)制成(cheng)(cheng)所要 求尺(chi)寸的(de)鋼(gang)管(guan)(guan)。采用的(de)穿孔和(he)軋(ya)管(guan)(guan) 辦(ban)法不同，就(jiu)構(gou)成(cheng)(cheng)了出產(chan)無縫鋼(gang)管(guan)(guan) 的(de)不同辦(ban)法。焊(han)(han)接鋼(gang)管(guan)(guan)出產(chan)進程是 將管(guan)(guan)坯(鋼(gang)板或(huo)帶鋼(gang))曲折成(cheng)(cheng)管(guan)(guan)狀， 再把縫隙焊(han)(han)接起來成(cheng)(cheng)為(wei)鋼(gang)管(guan)(guan)。因采 用的(de)成(cheng)(cheng)型和(he)焊(han)(han)接辦(ban)法不同，就(jiu)構(gou)成(cheng)(cheng)了出產(chan)焊(han)(han)接鋼(gang)管(guan)(guan)的(de)不同辦(ban)法。

無(wu)縫鋼(gang)管(guan)(guan)首要(yao)用(yong)熱軋法出產(chan)。 揉捏法首要(yao)用(yong)于出產(chan)難穿孔(kong)的低(di)塑 性高(gao)合金鋼(gang)管(guan)(guan)或異(yi)型鋼(gang)管(guan)(guan)和(he)復合金 屬(shu)管(guan)(guan)。冷軋和(he)冷拔法可將熱軋管(guan)(guan)繼(ji) 續加工成小直徑(jing)和(he)薄壁的鋼(gang)管(guan)(guan)。焊接鋼(gang)管(guan)(guan)工藝進(jin)程簡(jian)略、出產(chan) 效(xiao)率高(gao)、成本低(di)、產(chan)品品種日益擴(kuo) 大(da)。
