隨著我國(guo)(guo)經濟建設的快速(su)發展，不(bu)(bu)銹(xiu)鋼(gang)的消(xiao)費量(liang)(liang)不(bu)(bu)斷增(zeng)加，其(qi)中不(bu)(bu)銹(xiu)鋼(gang)管(guan)(guan)(guan)(guan)的需(xu)(xu)求(qiu)量(liang)(liang)同樣日趨擴大(da)，市(shi)場前(qian)景(jing)看好。不(bu)(bu)銹(xiu)鋼(gang)無(wu)(wu)縫管(guan)(guan)(guan)(guan)的市(shi)場需(xu)(xu)求(qiu)表現在基(ji)礎工(gong)(gong)(gong)(gong)業(ye)方面，如石油、化工(gong)(gong)(gong)(gong)、發電等(deng)(deng)(deng)(deng)，其(qi)需(xu)(xu)求(qiu)量(liang)(liang)占不(bu)(bu)銹(xiu)鋼(gang)無(wu)(wu)縫管(guan)(guan)(guan)(guan)消(xiao)耗(hao)(hao)總量(liang)(liang)的三分之一(yi)，還有(you)(you)如汽(qi)車(che)，造船，建筑和環(huan)保業(ye)等(deng)(deng)(deng)(deng)也有(you)(you)較大(da)需(xu)(xu)求(qiu)。不(bu)(bu)銹(xiu)鋼(gang)焊(han)(han)管(guan)(guan)(guan)(guan)主(zhu)(zhu)要用(yong)(yong)于換熱(re)器(qi)管(guan)(guan)(guan)(guan)、流體(ti)(ti)管(guan)(guan)(guan)(guan)、壓力管(guan)(guan)(guan)(guan)道、機(ji)械結構用(yong)(yong)管(guan)(guan)(guan)(guan)、城市(shi)景(jing)觀、等(deng)(deng)(deng)(deng)行業(ye)上(shang)，年消(xiao)耗(hao)(hao)量(liang)(liang)在70萬(wan)t左右。工(gong)(gong)(gong)(gong)業(ye)用(yong)(yong)不(bu)(bu)銹(xiu)鋼(gang)焊(han)(han)管(guan)(guan)(guan)(guan)需(xu)(xu)求(qiu)比較高(gao)，而(er)且生產(chan)(chan)工(gong)(gong)(gong)(gong)藝成(cheng)熟,目前(qian)我國(guo)(guo)年用(yong)(yong)工(gong)(gong)(gong)(gong)業(ye)用(yong)(yong)不(bu)(bu)銹(xiu)鋼(gang)焊(han)(han)管(guan)(guan)(guan)(guan)量(liang)(liang)大(da)約(yue)15萬(wan)t左右，一(yi)部分仍需(xu)(xu)要進口。 從(cong)國(guo)(guo)產(chan)(chan)不(bu)(bu)銹(xiu)鋼(gang)管(guan)(guan)(guan)(guan)產(chan)(chan)品上(shang)看，鋼(gang)種(zhong)以奧氏體(ti)(ti)鋼(gang)為主(zhu)(zhu);產(chan)(chan)品品種(zhong)有(you)(you):無(wu)(wu)縫鋼(gang)管(guan)(guan)(guan)(guan)包括冷(leng)拉管(guan)(guan)(guan)(guan)、冷(leng)軋管(guan)(guan)(guan)(guan)、熱(re)擠(ji)壓管(guan)(guan)(guan)(guan)、離心鑄造管(guan)(guan)(guan)(guan)、旋壓管(guan)(guan)(guan)(guan);焊(han)(han)接(jie)管(guan)(guan)(guan)(guan)包括:等(deng)(deng)(deng)(deng)離子焊(han)(han)、氬弧焊(han)(han)、埋弧焊(han)(han)、光速(su)焊(han)(han)接(jie)和高(gao)頻焊(han)(han)接(jie)等(deng)(deng)(deng)(deng)焊(han)(han)管(guan)(guan)(guan)(guan)，所(suo)能生產(chan)(chan)的不(bu)(bu)銹(xiu)鋼(gang)管(guan)(guan)(guan)(guan)基(ji)本(ben)上(shang)覆蓋了世界(jie)各國(guo)(guo)標準(zhun)的品種(zhong)規格(ge)，不(bu)(bu)銹(xiu)鋼(gang)異型(xing)管(guan)(guan)(guan)(guan)的規格(ge)、品種(zhong)也達百種(zhong)以上(shang)，產(chan)(chan)品用(yong)(yong)途涉及工(gong)(gong)(gong)(gong)業(ye)、民用(yong)(yong)的眾多領域。但是總體(ti)(ti)來說(shuo)，國(guo)(guo)產(chan)(chan)不(bu)(bu)銹(xiu)鋼(gang)管(guan)(guan)(guan)(guan)在品種(zhong)、規格(ge)、數量(liang)(liang)等(deng)(deng)(deng)(deng)方面，與市(shi)場需(xu)(xu)求(qiu)有(you)(you)一(yi)定(ding)的差距
