蘭(lan)州球(qiu)墨鑄鐵(tie)管至(zhi)于出貨方面(mian)，受市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)情緒帶動今(jin)日(ri)(ri)成(cheng)交(jiao)情況好于前兩日(ri)(ri)，且國(guo)(guo)(guo)內(nei)(nei)部(bu)(bu)分(fen)(fen)終端企業(ye)今(jin)年工程計(ji)劃逐(zhu)(zhu)漸落地(di)(di)，下游不乏采購商(shang)(shang)(shang)戶(hu)，尤其議價(jia)接單較為理想。近(jin)(jin)期(qi)(qi)(qi)各(ge)(ge)地(di)(di)爆發奧密克(ke)戎傳(chuan)播病例，市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)工人運(yun)輸(shu)、核酸(suan)檢測(ce)等成(cheng)本(ben)上升(sheng)，短期(qi)(qi)(qi)內(nei)(nei)對價(jia)格(ge)(ge)(ge)(ge)仍有(you)支(zhi)撐。預計(ji)明(ming)日(ri)(ri)全(quan)國(guo)(guo)(guo)消(xiao)防球(qiu)墨管價(jia)格(ge)(ge)(ge)(ge)持續上行.綜(zong)合來看，今(jin)日(ri)(ri)國(guo)(guo)(guo)內(nei)(nei)球(qiu)墨鑄鐵(tie)管市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)價(jia)格(ge)(ge)(ge)(ge)暫穩(wen)。江(jiang)蘇、浙江(jiang)、山(shan)東地(di)(di)區(qu)受期(qi)(qi)(qi)貨上行影(ying)響(xiang)，市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)價(jia)格(ge)(ge)(ge)(ge)跟隨小漲。下游需(xu)求(qiu)逐(zhu)(zhu)步減(jian)弱(ruo)(ruo)，部(bu)(bu)分(fen)(fen)地(di)(di)區(qu)規格(ge)(ge)(ge)(ge)仍存在緊(jin)缺現(xian)象，資本(ben)市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)上行，市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)心(xin)態好轉。雖(sui)然(ran)近(jin)(jin)期(qi)(qi)(qi)復產鋼(gang)(gang)(gang)廠不斷增多，市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)到(dao)貨情況陸續好轉，但目前庫存依然(ran)處(chu)于低位，且近(jin)(jin)期(qi)(qi)(qi)原料價(jia)格(ge)(ge)(ge)(ge)持續反彈(dan)短期(qi)(qi)(qi)對價(jia)格(ge)(ge)(ge)(ge)尚有(you)一定支(zhi)撐。預計(ji)明(ming)日(ri)(ri)國(guo)(guo)(guo)內(nei)(nei)給水球(qiu)墨鑄鐵(tie)管市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)價(jia)格(ge)(ge)(ge)(ge)暫穩(wen)。國(guo)(guo)(guo)內(nei)(nei)球(qiu)墨鑄鐵(tie)管市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)型(xing)(xing)(xing)材(cai)(cai)(cai)價(jia)格(ge)(ge)(ge)(ge)偏(pian)弱(ruo)(ruo)運(yun)行，市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)整(zheng)體(ti)成(cheng)交(jiao)一般，預計(ji)明(ming)日(ri)(ri)偏(pian)強運(yun)行。今(jin)日(ri)(ri)國(guo)(guo)(guo)內(nei)(nei)各(ge)(ge)地(di)(di)市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)型(xing)(xing)(xing)材(cai)(cai)(cai)主流價(jia)格(ge)(ge)(ge)(ge)盤(pan)整(zheng)，期(qi)(qi)(qi)鋼(gang)(gang)(gang)提振(zhen)拉漲。據各(ge)(ge)地(di)(di)貿(mao)易商(shang)(shang)(shang)反饋，今(jin)日(ri)(ri)國(guo)(guo)(guo)內(nei)(nei)型(xing)(xing)(xing)材(cai)(cai)(cai)現(xian)貨價(jia)格(ge)(ge)(ge)(ge)以穩(wen)為主，主要(yao)還是(shi)(shi)下游需(xu)求(qiu)較弱(ruo)(ruo)的原因，雖(sui)然(ran)期(qi)(qi)(qi)鋼(gang)(gang)(gang)拉漲，但是(shi)(shi)市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)交(jiao)投(tou)(tou)一般。南方大部(bu)(bu)分(fen)(fen)鋼(gang)(gang)(gang)廠沒有(you)冬儲政策，鋼(gang)(gang)(gang)貿(mao)商(shang)(shang)(shang)大部(bu)(bu)分(fen)(fen)按需(xu)拿(na)貨。北(bei)方貿(mao)易商(shang)(shang)(shang)由(you)于近(jin)(jin)期(qi)(qi)(qi)期(qi)(qi)(qi)現(xian)價(jia)格(ge)(ge)(ge)(ge)拉漲，少(shao)量(liang)儲貨。今(jin)日(ri)(ri)唐山(shan)地(di)(di)區(qu)型(xing)(xing)(xing)材(cai)(cai)(cai)價(jia)格(ge)(ge)(ge)(ge)穩(wen)中偏(pian)強，期(qi)(qi)(qi)鋼(gang)(gang)(gang)上漲，刺激市(shi)(shi)(shi)(shi)場(chang)(chang)(chang)交(jiao)投(tou)(tou)氣氛，整(zheng)體(ti)成(cheng)交(jiao)較好。
