Steel Tube)具有中空截面、周邊沒有接縫的長(zhǎng)條鋼材。鋼管具有中空截面，大量用作輸送流體的管道，如輸送石油、天然氣、煤氣、水及某些固體物料的管道等。合金無縫鋼管與圓鋼等實(shí)心鋼材相比，在抗彎抗扭強(qiáng)度相同時(shí)，重量較輕，是一種經(jīng)濟(jì)截面鋼材，廣泛用于制造結(jié)構(gòu)件和機(jī)械零件，如石油輸送、樓梯扶手、自行車架以及建筑施工中用的鋼腳手架等。用合金無縫鋼管制造環(huán)形零件，可提高材料利用率，簡(jiǎn)化制造工序，節(jié)約材料和加工工時(shí)，如滾動(dòng)軸承套圈、千斤頂套等，已廣泛用鋼管來制造。合金無縫鋼管還是各種常規(guī)武器不可缺少的材料，槍管、炮筒等都要鋼管來制造。此外，圓環(huán)截面在承受內(nèi)部或外部徑向壓力時(shí)，受力較均勻，因此，絕大多數(shù)合金無縫鋼管是圓管
