三、焊(han)(han)(han)(han)(han)(han)接(jie)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)焊(han)(han)(han)(han)(han)(han)接(jie)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)也稱焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan),是(shi)用鋼(gang)(gang)(gang)板或鋼(gang)(gang)(gang)帶(dai)經過卷曲(qu)成(cheng)型后焊(han)(han)(han)(han)(han)(han)接(jie)制成(cheng)的(de)(de)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。焊(han)(han)(han)(han)(han)(han)接(jie)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)生(sheng)產(chan)(chan)工藝簡(jian)單,生(sheng)產(chan)(chan)效(xiao)率高,品(pin)種規(gui)格多,設備(bei)資金少(shao),但(dan)一般強度(du)低于無(wu)縫鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。20世紀30年代以(yi)來,隨著優質(zhi)帶(dai)鋼(gang)(gang)(gang)連軋生(sheng)產(chan)(chan)的(de)(de)迅速(su)發(fa)展(zhan)以(yi)及焊(han)(han)(han)(han)(han)(han)接(jie)和(he)(he)檢(jian)驗技術(shu)的(de)(de)進步,焊(han)(han)(han)(han)(han)(han)縫質(zhi)量不(bu)斷(duan)提高,焊(han)(han)(han)(han)(han)(han)接(jie)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)品(pin)種規(gui)格日益(yi)增(zeng)多,并在越(yue)來越(yue)多的(de)(de)領域代替了無(wu)縫鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。焊(han)(han)(han)(han)(han)(han)接(jie)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)按焊(han)(han)(han)(han)(han)(han)縫的(de)(de)形(xing)式分為直(zhi)縫焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)和(he)(he)螺旋焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。直(zhi)縫焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)生(sheng)產(chan)(chan)工藝簡(jian)單,生(sheng)產(chan)(chan)效(xiao)率高,成(cheng)本低,發(fa)展(zhan)較快。螺旋焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)強度(du)一般比直(zhi)縫焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)高,能(neng)用較窄的(de)(de)坯(pi)料生(sheng)產(chan)(chan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)徑(jing)較大的(de)(de)焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan),還可(ke)以(yi)用同樣(yang)寬度(du)的(de)(de)坯(pi)料生(sheng)產(chan)(chan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)徑(jing)不(bu)同的(de)(de)焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。但(dan)是(shi)與相(xiang)同長度(du)的(de)(de)直(zhi)縫管(guan)(guan)(guan)(guan)(guan)(guan)(guan)相(xiang)比,焊(han)(han)(han)(han)(han)(han)縫長度(du)增(zeng)加30~100%,而(er)且生(sheng)產(chan)(chan)速(su)度(du)較低。因此(ci),較小口徑(jing)的(de)(de)焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)大都采用直(zhi)縫焊(han)(han)(han)(han)(han)(han),大口徑(jing)焊(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)則大多采用螺旋焊(han)(han)(han)(han)(han)(han)。
