出產辦法

鋼(gang)(gang)管(guan)分為 無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)和(he)焊(han)(han)接鋼(gang)(gang)管(guan)。無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)生 產(chan)(chan)進程是將實(shi)心管(guan)坯或鋼(gang)(gang)錠穿(chuan)成(cheng)(cheng)空 心的(de)毛(mao)管(guan)，然(ran)后再將其軋制(zhi)成(cheng)(cheng)所要 求(qiu)尺寸(cun)的(de)鋼(gang)(gang)管(guan)。采用的(de)穿(chuan)孔(kong)和(he)軋管(guan) 辦(ban)(ban)法不(bu)同，就構成(cheng)(cheng)了(le)出(chu)產(chan)(chan)無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan) 的(de)不(bu)同辦(ban)(ban)法。焊(han)(han)接鋼(gang)(gang)管(guan)出(chu)產(chan)(chan)進程是 將管(guan)坯(鋼(gang)(gang)板或帶鋼(gang)(gang))曲折成(cheng)(cheng)管(guan)狀， 再把縫(feng)(feng)(feng)隙焊(han)(han)接起來成(cheng)(cheng)為鋼(gang)(gang)管(guan)。因采 用的(de)成(cheng)(cheng)型(xing)和(he)焊(han)(han)接辦(ban)(ban)法不(bu)同，就構成(cheng)(cheng)了(le)出(chu)產(chan)(chan)焊(han)(han)接鋼(gang)(gang)管(guan)的(de)不(bu)同辦(ban)(ban)法。

無縫鋼(gang)管(guan)首要(yao)用熱(re)軋法出(chu)產(chan)(chan)。 揉捏法首要(yao)用于出(chu)產(chan)(chan)難穿(chuan)孔的(de)低(di)塑 性高(gao)(gao)合(he)金鋼(gang)管(guan)或異型鋼(gang)管(guan)和復合(he)金 屬管(guan)。冷(leng)軋和冷(leng)拔法可將熱(re)軋管(guan)繼 續(xu)加工成小(xiao)直徑和薄壁的(de)鋼(gang)管(guan)。焊(han)接鋼(gang)管(guan)工藝進程簡略、出(chu)產(chan)(chan) 效率高(gao)(gao)、成本低(di)、產(chan)(chan)品(pin)品(pin)種日益擴(kuo) 大。
