無縫鋼管用(yong)(yong)途(tu)很廣(guang)泛。一般用(yong)(yong)途(tu)的(de)無(wu)(wu)縫鋼(gang)(gang)管(guan)由(you)普通的(de)碳素結(jie)(jie)構(gou)鋼(gang)(gang)、低合(he)金結(jie)(jie)構(gou)鋼(gang)(gang)或合(he)金結(jie)(jie)構(gou)鋼(gang)(gang)軋制，產量最多，主要(yao)用(yong)(yong)作輸送(song)流體(ti)的(de)管(guan)道或結(jie)(jie)構(gou)零件。.2、根據(ju)用(yong)(yong)途(tu)不同(tong)分三類供(gong)(gong)(gong)(gong)(gong)應(ying)(ying)：a、按化(hua)學成分和機械性能供(gong)(gong)(gong)(gong)(gong)應(ying)(ying);b、按機械性能供(gong)(gong)(gong)(gong)(gong)應(ying)(ying);c、按水(shui)壓(ya)試(shi)(shi)驗供(gong)(gong)(gong)(gong)(gong)應(ying)(ying)。按a、b類供(gong)(gong)(gong)(gong)(gong)應(ying)(ying)的(de)鋼(gang)(gang)管(guan)，如用(yong)(yong)于承受液體(ti)壓(ya)力(li)，也要(yao)進行水(shui)壓(ya)試(shi)(shi)驗。3、專門用(yong)(yong)途(tu)的(de)無(wu)(wu)縫管(guan)有鍋爐用(yong)(yong)無(wu)(wu)縫管(guan)、化(hua)工電力(li)用(yong)(yong)，地質用(yong)(yong)無(wu)(wu)縫鋼(gang)(gang)管(guan)及石(shi)油用(yong)(yong)無(wu)(wu)縫管(guan)等(deng)多種。
19日(ri)福州無縫鋼(gang)管價格(ge)暫(zan)穩，市(shi)場成(cheng)交清淡。截(jie)至發稿時，臨沂(yi)金正陽Ф57*3.5mm報4850元(yuan)/噸(dun)(dun)，Ф108*4.5mm報4700元(yuan)/噸(dun)(dun)，Ф219*6mm報4750元(yuan)/噸(dun)(dun)。
今(jin)日山東熱軋管(guan)(guan)(guan)坯價格跌10元/噸，目前(qian)Ф75-130mm報3620元/噸，山東管(guan)(guan)(guan)廠方面部分跟漲50元/噸，福(fu)州市(shi)(shi)場(chang)無(wu)(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)價格暫無(wu)(wu)調整。據了解，山東管(guan)(guan)(guan)廠方面近期(qi)無(wu)(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)成交尚(shang)可，目前(qian)暫無(wu)(wu)庫存(cun)壓力，且原料管(guan)(guan)(guan)坯價格較(jiao)高(gao)，出廠價格有成本(ben)支撐。福(fu)州近日受海外疫情輸入影響，市(shi)(shi)場(chang)管(guan)(guan)(guan)控加強，無(wu)(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)整體(ti)成交較(jiao)弱，商家漲價意愿(yuan)不強。綜合來看，預(yu)計短期(qi)內福(fu)州無(wu)(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)價格盤整運行。
