日前(qian)，鞍鋼獨家(jia)中標國(guo)家(jia)重點工程(cheng)——中俄(e)原油管道二線(xian)工程(cheng)（又稱(cheng)漠大復線(xian)）全部4個標段的X65M熱(re)軋卷板(ban)和熱(re)軋平(ping)板(ban)，總(zong)計25萬(wan)噸。這為中俄(e)戰略協(xie)作伙伴關系建立20周年添上喜慶的一筆。
中(zhong)俄(e)原油(you)管道工(gong)(gong)程(cheng)是(shi)我國正(zheng)在構(gou)建的東(dong)北、西北、西南和海上四大能源戰(zhan)略通道之(zhi)一。中(zhong)俄(e)原油(you)管道二(er)線(xian)工(gong)(gong)程(cheng)是(shi)近三年國內最(zui)大管道工(gong)(gong)程(cheng)，始(shi)于漠河(he)縣，止于大慶市，全長941.8公里，全線(xian)采用(yong)X65M螺旋縫埋弧焊(han)鋼(gang)(gang)管和直縫埋弧焊(han)鋼(gang)(gang)管。計劃(hua)2017年建成(cheng)投(tou)產，建成(cheng)后(hou)將(jiang)成(cheng)為我國北方(fang)重(zhong)要(yao)(yao)的油(you)氣(qi)戰(zhan)略通道。工(gong)(gong)程(cheng)地處高寒地區，最(zui)低氣(qi)溫(wen)(wen)達零(ling)下(xia)(xia)58.2攝氏度(du)，其(qi)工(gong)(gong)程(cheng)技術難度(du)大、要(yao)(yao)求(qiu)(qiu)高。特別是(shi)對管道原材料即制管用(yong)卷板(ban)和平板(ban)的要(yao)(yao)求(qiu)(qiu)，低溫(wen)(wen)韌(ren)性要(yao)(yao)求(qiu)(qiu)遠遠高于常規管線(xian)鋼(gang)(gang)，其(qi)落錘試驗溫(wen)(wen)度(du)為零(ling)下(xia)(xia)25攝氏度(du)，低溫(wen)(wen)韌(ren)脆轉變溫(wen)(wen)度(du)要(yao)(yao)求(qiu)(qiu)在零(ling)下(xia)(xia)40攝氏度(du)以下(xia)(xia)。
管(guan)線鋼(gang)(gang)(gang)是(shi)鞍(an)鋼(gang)(gang)(gang)的戰略品(pin)(pin)牌產品(pin)(pin)，已具(ju)備X80鋼(gang)(gang)(gang)級(ji)以下管(guan)線鋼(gang)(gang)(gang)產品(pin)(pin)品(pin)(pin)種(zhong)和規格的全覆蓋，可滿足(zu)國內外管(guan)線工程(cheng)各種(zhong)鋼(gang)(gang)(gang)材需(xu)求(qiu)。在西氣(qi)東(dong)輸、陜京二線、川氣(qi)東(dong)送、中(zhong)(zhong)(zhong)俄原油管(guan)道一線、沿(yan)海LNG管(guan)線、南海荔灣管(guan)線等國家重點工程(cheng)中(zhong)(zhong)(zhong)，鞍(an)鋼(gang)(gang)(gang)管(guan)線鋼(gang)(gang)(gang)均作出過重要(yao)貢獻。面對中(zhong)(zhong)(zhong)俄原油管(guan)道二線工程(cheng)對產品(pin)(pin)的苛刻要(yao)求(qiu)，鞍(an)鋼(gang)(gang)(gang)也(ye)是(shi)以實力(li)說話，最(zui)終以完(wan)善的產品(pin)(pin)設(she)計(ji)方案和產品(pin)(pin)試制生產計(ji)劃(hua)順利中(zhong)(zhong)(zhong)標(biao)。
目前，鞍(an)鋼(gang)針對漠大(da)復線(xian)(xian)(xian)(xian)工(gong)程用卷板(ban)和平板(ban)的(de)試(shi)(shi)制工(gong)作，已分別在(zai)鞍(an)鋼(gang)股(gu)份熱軋帶鋼(gang)廠(chang)2150ASP生產線(xian)(xian)(xian)(xian)、中厚板(ban)廠(chang)4300毫米(mi)生產線(xian)(xian)(xian)(xian)、鲅魚圈分公司 5500毫米(mi)生產線(xian)(xian)(xian)(xian)等三條(tiao)生產線(xian)(xian)(xian)(xian)有(you)序開展，待(dai)試(shi)(shi)制產品檢驗合格后將進行(xing)制管試(shi)(shi)制，保證(zheng)供貨質(zhi)量，讓中俄原油管道二線(xian)(xian)(xian)(xian)工(gong)程成為鞍(an)鋼(gang)管線(xian)(xian)(xian)(xian)鋼(gang)的(de)又一精品工(gong)程。
