當然，無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)不(bu)但在(zai)生(sheng)活工(gong)業中(zhong)(zhong)起(qi)著重要(yao)作，在(zai)工(gong)業中(zhong)(zhong)也(ye)是(shi)(shi)重要(yao)生(sheng)產材料。比(bi)如一(yi)些火身(shen)管(guan)(guan)(guan)(guan)(guan)，艦艇動力裝(zhuang)置冷卻管(guan)(guan)(guan)(guan)(guan)，潛艇 發(fa)射管(guan)(guan)(guan)(guan)(guan)等，都被(bei)認為是(shi)(shi)軍工(gong)管(guan)(guan)(guan)(guan)(guan)。它特點(dian)是(shi)(shi)：產量相對很(hen)低，但是(shi)(shi)技術(shu)含量和(he)造(zao)價(jia)(jia)(jia)(jia)都比(bi)較(jiao)高，是(shi)(shi)高品級無(wu)(wu)(wu)縫(feng)(feng)管(guan)(guan)(guan)(guan)(guan)主(zhu)(zhu)要(yao)表(biao)。 　　無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)主(zhu)(zhu)要(yao)在(zai)管(guan)(guan)(guan)(guan)(guan)道運輸中(zhong)(zhong)，可(ke)以(yi)被(bei)來運輸一(yi)些流體(ti)，比(bi)如，一(yi)些能源等等，石和(he)天然氣(qi)已經一(yi)些地(di)下水運輸，都可(ke)以(yi)依靠無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)來實現(xian)，在(zai)現(xian)社會中(zhong)(zhong)，無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)使領域(yu)和(he)范(fan)圍再一(yi)次得(de)16Mn無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)途(tu)很(hen)廣泛。 　　同(tong)時(shi)冷軋無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)壁厚，一(yi)般比(bi)熱軋無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)要(yao)小。但是(shi)(shi)表(biao)面看起(qi)來，比(bi)厚壁無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)更加明亮，表(biao)面沒有(you)太(tai)(tai)多(duo)粗糙，也(ye)沒有(you)太(tai)(tai)多(duo)毛(mao)刺。如果你所購(gou)買(mai)管(guan)(guan)(guan)(guan)(guan)道，表(biao)現(xian)有(you)著明顯不(bu)同(tong)。那么就(jiu)要(yao)小心了(le)，因(yin)為這(zhe)樣管(guan)(guan)(guan)(guan)(guan)道，很(hen)有(you)可(ke)能在(zai)質(zhi)量方面，并不(bu)是(shi)(shi)那么合格。 　　據(ju)分析，在(zai)建(jian)筑鋼(gang)(gang)(gang)市(shi)場上(shang)，價(jia)(jia)(jia)(jia)格盤整偏弱(ruo)。濟南(nan)、福州、廣州等地(di)噸(dun)價(jia)(jia)(jia)(jia)一(yi)周(zhou)上(shang)漲(zhang)10元至(zhi)50元;而杭(hang)州、武漢(han)、沈陽等地(di)噸(dun)價(jia)(jia)(jia)(jia)一(yi)周(zhou)下跌10元至(zhi)160元。從上(shang)海(hai)等地(di)可(ke)以(yi)看到，鋼(gang)(gang)(gang)材價(jia)(jia)(jia)(jia)格沖高回(hui)落(luo)。需求端基礎并不(bu)牢固，只要(yao)價(jia)(jia)(jia)(jia)格一(yi)上(shang)攻，需求就(jiu)下降。
