無(wu)縫鋼(gang)管(guan)用(yong)(yong)(yong)(yong)途(tu)很廣泛(fan)。一般用(yong)(yong)(yong)(yong)途(tu)的(de)無(wu)縫鋼(gang)管(guan)由普通的(de)碳素結(jie)構(gou)鋼(gang)、低合金結(jie)構(gou)鋼(gang)或合金結(jie)構(gou)鋼(gang)軋制(zhi)，產量最多(duo)，主(zhu)要(yao)用(yong)(yong)(yong)(yong)作輸送流體的(de)管(guan)道或結(jie)構(gou)零件。.2、根據用(yong)(yong)(yong)(yong)途(tu)不同分(fen)三類供應(ying)：a、按化學成分(fen)和機械(xie)性能(neng)供應(ying)；b、按機械(xie)性能(neng)供應(ying)；c、按水壓(ya)試(shi)驗供應(ying)。按a、b類供應(ying)的(de)鋼(gang)管(guan)，如用(yong)(yong)(yong)(yong)于承(cheng)受液體壓(ya)力，也要(yao)進行水壓(ya)試(shi)驗。3、專門用(yong)(yong)(yong)(yong)途(tu)的(de)無(wu)縫管(guan)有鍋爐用(yong)(yong)(yong)(yong)無(wu)縫管(guan)、化工電力用(yong)(yong)(yong)(yong)，地質用(yong)(yong)(yong)(yong)無(wu)縫鋼(gang)管(guan)及(ji)石油(you)用(yong)(yong)(yong)(yong)無(wu)縫管(guan)等多(duo)種。
無縫(feng)鋼(gang)管具(ju)有中空截(jie)面，大量(liang)用(yong)作(zuo)輸送流體的管道，如輸送石油、天然氣(qi)、煤氣(qi)、水及某(mou)些固體物料的管道等(deng)。鋼(gang)管與圓鋼(gang)等(deng)實心鋼(gang)材(cai)相比，在抗(kang)(kang)彎抗(kang)(kang)扭強度(du)相同時，重量(liang)較(jiao)輕，是(shi)一種經濟截(jie)面鋼(gang)材(cai)。
廣(guang)泛(fan)用于制(zhi)(zhi)造(zao)結構(gou)件和(he)機械零(ling)件，如石油鉆桿、汽車傳動軸(zhou)、自行車架(jia)以及建筑施工(gong)(gong)(gong)中(zhong)用的鋼(gang)腳手(shou)架(jia)等用鋼(gang)管(guan)制(zhi)(zhi)造(zao)環形零(ling)件，可提(ti)高材(cai)料利用率，簡(jian)化(hua)制(zhi)(zhi)造(zao)工(gong)(gong)(gong)序，節(jie)約(yue)材(cai)料和(he)加工(gong)(gong)(gong)工(gong)(gong)(gong)時，已(yi)廣(guang)泛(fan)用鋼(gang)管(guan)來(lai)制(zhi)(zhi)造(zao)
