無縫鋼管：精軋管提前準備及查驗△→精軋管加溫→破孔→軋管→無縫鋼管再(zai)加溫→定(ding)(減)徑→調質處理△→制成品管校直→鑄(zhu)軋→檢測△(高質量、物理化學、臺檢) →進庫
②冷扎(拔)無縫鋼管關鍵生產制造(zao)工藝流程：
胚(pei)料(liao)提前準備→酸洗鈍化(hua)潤化(hua)→冷扎(zha)(拔)→調質處理→校直(zhi)→鑄軋→檢(jian)測 普遍(bian)用以生產(chan)制造(zao)零(ling)部件(jian)和機械(xie)零(ling)件(jian)，如原(yuan)油鉆具、傳動軸、自行車車架及其建(jian)筑工(gong)(gong)程施工(gong)(gong)連用的(de)鋼鋼管腳手架等(deng)用無縫(feng)鋼管生產(chan)制造(zao)環狀零(ling)件(jian)，可(ke)提升(sheng)原(yuan)材(cai)料(liao)使用率，簡單(dan)化(hua)生產(chan)制造(zao)工(gong)(gong)藝流程，節省(sheng)原(yuan)材(cai)料(liao)和生產(chan)加工(gong)(gong)綜合工(gong)(gong)時，已普遍(bian)用無縫(feng)鋼管來生產(chan)制造(zao)。
無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)的優勢是耐(nai)壓試(shi)驗高,延展性好(hao),管(guan)(guan)(guan)段(duan)長而插口少.缺陷是價錢高,易浸蝕,因此(ci)應(ying)用周期(qi)短.無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)生產制造的生產加(jia)工(gong)加(jia)工(gong)工(gong)藝(yi)可分成冷(leng)(leng)拉(la)、冷(leng)(leng)扎、熱(re)扎、熱(re)擴四(si)種基(ji)礎(chu)方(fang)法(fa)，無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)的材料為10 20 35 45#稱之為 普通鋼(gang)管(guan)(guan)(guan)，依照主要用途分成構(gou)造用無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);運輸用無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);加(jia)熱(re)爐用無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);加(jia)熱(re)爐用髙壓無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);有(you)機(ji)肥機(ji)器設備(bei)用髙壓無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);地質(zhi)學磚探用無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);原油磚探用無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);原油裂化用無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);船只用無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);冷(leng)(leng)拉(la)冷(leng)(leng)扎高精密無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan);各種各樣合金(jin)管(guan)(guan)(guan)。無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)表(biao)達方(fang)式(shi)為直徑，壁厚，薄壁無(wu)(wu)(wu)(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)適用于(yu)機(ji)械加(jia)工(gong)制造，媒礦，液(ye)壓機(ji)鋼(gang)，等幾種主要用途。
