2016年(nian)(nian)以來,隨著(zhu)油(you)價和鋼管(guan)價格上漲以及市場需求的回升,國內(nei)一批企(qi)業又(you)在新(xin)建熱(re)(re)軋(ya)(ya)無(wu)(wu)縫管(guan)產(chan)線,無(wu)(wu)縫管(guan)產(chan)能又(you)呈(cheng)快速增長趨勢,從表(biao)6-1~表(biao)6-8統計分析,2015年(nian)(nian)至2018年(nian)(nian)底,我(wo)國新(xin)建熱(re)(re)軋(ya)(ya)無(wu)(wu)縫鋼管(guan)產(chan)線28條,產(chan)能738萬(wan)噸(含(han)在建機組(zu)產(chan)能)。其(qi)中,熱(re)(re)連軋(ya)(ya)機組(zu)17條,產(chan)能595萬(wan)噸;三輥斜軋(ya)(ya)管(guan)機(ji)組(zu)11條(tiao),產(chan)(chan)能(neng)(neng)(neng)143萬(wan)噸(dun),到2018年(nian)底,我國(guo)無縫鋼(gang)管(guan)機(ji)組(zu)的實(shi)際產(chan)(chan)能(neng)(neng)(neng)約為4074萬(wan)噸(dun)(含在建機(ji)組(zu)產(chan)(chan)能(neng)(neng)(neng)),若不考(kao)慮(lv)在建產(chan)(chan)能(neng)(neng)(neng),實(shi)際生(sheng)產(chan)(chan)機(ji)組(zu)產(chan)(chan)能(neng)(neng)(neng)約為3649萬(wan)噸(dun)。2018年(nian)我國(guo)無縫鋼(gang)管(guan)產(chan)(chan)量2482.87萬(wan)噸(dun),產(chan)(chan)能(neng)(neng)(neng)利(li)用(yong)率為68%,2019年(nian)隨著(zhu)我國(guo)無縫管(guan)在建機(ji)組(zu)的投產(chan)(chan),產(chan)(chan)能(neng)(neng)(neng)利(li)用(yong)率還將進一步下降(jiang)。
