1.熱軋(ya)(ya)(ya)（擠(ji)(ji)(ji)壓(ya)(ya)無(wu)(wu)(wu)縫(feng)(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)）：圓(yuan)管(guan)(guan)(guan)(guan)坯→加(jia)熱→穿孔(kong)→三(san)輥斜(xie)軋(ya)(ya)(ya)、連(lian)軋(ya)(ya)(ya)或(huo)擠(ji)(ji)(ji)壓(ya)(ya)→脫管(guan)(guan)(guan)(guan)→定(ding)(ding)徑(jing)(jing)（或(huo)減徑(jing)(jing)）→冷(leng)(leng)(leng)(leng)卻(que)→矯(jiao)直(zhi)→水壓(ya)(ya)試驗(yan)(yan)（或(huo)探傷(shang)）→標(biao)記→入(ru)庫 軋(ya)(ya)(ya)制(zhi)無(wu)(wu)(wu)縫(feng)(feng)(feng)管(guan)(guan)(guan)(guan)的(de)(de)(de)原(yuan)料(liao)(liao)是(shi)圓(yuan)管(guan)(guan)(guan)(guan)坯，圓(yuan)管(guan)(guan)(guan)(guan)胚(pei)(pei)要(yao)(yao)經(jing)(jing)過(guo)(guo)切割機(ji)(ji)(ji)(ji)的(de)(de)(de)切割加(jia)工成長(chang)度(du)約為1米的(de)(de)(de)坯料(liao)(liao)，并(bing)經(jing)(jing)傳(chuan)送(song)(song)帶送(song)(song)到熔爐內(nei)(nei)加(jia)熱。鋼(gang)(gang)(gang)坯被(bei)(bei)送(song)(song)入(ru)熔爐內(nei)(nei)加(jia)熱，溫度(du)大(da)約為1200攝(she)氏度(du)。燃料(liao)(liao)為氫氣(qi)(qi)或(huo)乙炔。爐內(nei)(nei)溫度(du)控制(zhi)是(shi)關(guan)鍵(jian)性的(de)(de)(de)問(wen)題(ti).圓(yuan)管(guan)(guan)(guan)(guan)坯出爐后(hou)(hou)(hou)(hou)(hou)要(yao)(yao)經(jing)(jing)過(guo)(guo)壓(ya)(ya)力穿孔(kong)機(ji)(ji)(ji)(ji)進行(xing)穿空。一般較常見的(de)(de)(de)穿孔(kong)機(ji)(ji)(ji)(ji)是(shi)錐形輥穿孔(kong)機(ji)(ji)(ji)(ji)，這(zhe)種穿孔(kong)機(ji)(ji)(ji)(ji)生(sheng)產效(xiao)率高，產品質(zhi)量(liang)好，穿孔(kong)擴徑(jing)(jing)量(liang)大(da)，可(ke)穿多(duo)種鋼(gang)(gang)(gang)種。穿孔(kong)后(hou)(hou)(hou)(hou)(hou)，圓(yuan)管(guan)(guan)(guan)(guan)坯就先后(hou)(hou)(hou)(hou)(hou)被(bei)(bei)三(san)輥斜(xie)軋(ya)(ya)(ya)、連(lian)軋(ya)(ya)(ya)或(huo)擠(ji)(ji)(ji)壓(ya)(ya)。擠(ji)(ji)(ji)壓(ya)(ya)后(hou)(hou)(hou)(hou)(hou)要(yao)(yao)脫管(guan)(guan)(guan)(guan)定(ding)(ding)徑(jing)(jing)。定(ding)(ding)徑(jing)(jing)機(ji)(ji)(ji)(ji)通(tong)過(guo)(guo)錐形鉆(zhan)頭(tou)(tou)(tou)高速旋轉入(ru)鋼(gang)(gang)(gang)胚(pei)(pei)打(da)(da)孔(kong)，形成鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)。鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)內(nei)(nei)徑(jing)(jing)由定(ding)(ding)徑(jing)(jing)機(ji)(ji)(ji)(ji)鉆(zhan)頭(tou)(tou)(tou)的(de)(de)(de)外(wai)徑(jing)(jing)長(chang)度(du)來確定(ding)(ding)。鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)經(jing)(jing)定(ding)(ding)徑(jing)(jing)后(hou)(hou)(hou)(hou)(hou)，進入(ru)冷(leng)(leng)(leng)(leng)卻(que)塔中，通(tong)過(guo)(guo)噴水冷(leng)(leng)(leng)(leng)卻(que)，鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)經(jing)(jing)冷(leng)(leng)(leng)(leng)卻(que)后(hou)(hou)(hou)(hou)(hou)，就要(yao)(yao)被(bei)(bei)矯(jiao)直(zhi)。鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)經(jing)(jing)矯(jiao)直(zhi)后(hou)(hou)(hou)(hou)(hou)由傳(chuan)送(song)(song)帶送(song)(song)至金屬(shu)探傷(shang)機(ji)(ji)(ji)(ji)（或(huo)水壓(ya)(ya)實驗(yan)(yan)）進行(xing)內(nei)(nei)部探傷(shang)。若鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)內(nei)(nei)部有裂紋，氣(qi)(qi)泡(pao)等問(wen)題(ti)，將被(bei)(bei)探測出。鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)質(zhi)檢后(hou)(hou)(hou)(hou)(hou)還要(yao)(yao)通(tong)過(guo)(guo)嚴(yan)格的(de)(de)(de)手(shou)工挑選。鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)質(zhi)檢后(hou)(hou)(hou)(hou)(hou)，用油(you)(you)漆(qi)噴上編號(hao)、規(gui)格、生(sheng)產批(pi)號(hao)等。并(bing)由吊(diao)(diao)(diao)車(che)吊(diao)(diao)(diao)入(ru)倉庫中。
