無縫(feng)不(bu)銹鋼方管(guan)(guan)(guan)(guan)是(shi)一種具有(you)(you)(you)(you)中(zhong)空(kong)截(jie)(jie)面(mian)、周(zhou)(zhou)邊(bian)沒有(you)(you)(you)(you)接縫(feng)的(de)(de)長(chang)條鋼材(cai)。鋼管(guan)(guan)(guan)(guan)具有(you)(you)(you)(you)中(zhong)空(kong)截(jie)(jie)面(mian)，大量用(yong)作輸送(song)(song)流體的(de)(de)管(guan)(guan)(guan)(guan)道，如(ru)輸送(song)(song)石油、天然氣、煤氣、水(shui)及(ji)某些固體物料(liao)的(de)(de)管(guan)(guan)(guan)(guan)道等(deng)(deng)。鋼管(guan)(guan)(guan)(guan)與圓(yuan)鋼等(deng)(deng)實心鋼材(cai)相(xiang)比，在抗(kang)彎抗(kang)扭強度相(xiang)同(tong)時，重(zhong)量較(jiao)輕，是(shi)一種經濟截(jie)(jie)面(mian)鋼材(cai)，廣泛用(yong)于制造(zao)(zao)(zao)結構件和機械零件，如(ru)石油鉆桿(gan)、汽車(che)傳動(dong)軸(zhou)(zhou)、自(zi)行車(che)架(jia)以及(ji)建筑施工(gong)中(zhong)用(yong)的(de)(de)鋼腳手(shou)架(jia)等(deng)(deng)。用(yong)鋼管(guan)(guan)(guan)(guan)制造(zao)(zao)(zao)環形(xing)零件，可(ke)(ke)提高材(cai)料(liao)利用(yong)率，簡(jian)化制造(zao)(zao)(zao)工(gong)序，節約材(cai)料(liao)和加工(gong)工(gong)時，如(ru)滾動(dong)軸(zhou)(zhou)承(cheng)套(tao)圈、千斤頂套(tao)等(deng)(deng)，目前已廣泛用(yong)鋼管(guan)(guan)(guan)(guan)來制造(zao)(zao)(zao)。鋼管(guan)(guan)(guan)(guan)還(huan)是(shi)各種常規武器(qi)不(bu)可(ke)(ke)缺少的(de)(de)材(cai)料(liao)，槍管(guan)(guan)(guan)(guan)、炮筒等(deng)(deng)都要(yao)鋼管(guan)(guan)(guan)(guan)來制造(zao)(zao)(zao)。 鋼管(guan)(guan)(guan)(guan)按橫截(jie)(jie)面(mian)積(ji)形(xing)狀(zhuang)的(de)(de)不(bu)同(tong)可(ke)(ke)分為圓(yuan)管(guan)(guan)(guan)(guan)和異(yi)(yi)型管(guan)(guan)(guan)(guan)。由于在周(zhou)(zhou)長(chang)相(xiang)等(deng)(deng)的(de)(de)條件下，圓(yuan)面(mian)積(ji)，用(yong)圓(yuan)形(xing)管(guan)(guan)(guan)(guan)可(ke)(ke)以輸送(song)(song)更多(duo)的(de)(de)流體。此(ci)外，圓(yuan)環截(jie)(jie)面(mian)在承(cheng)受內部(bu)或外部(bu)徑向壓力時，受力較(jiao)均勻，因(yin)此(ci)，絕大多(duo)數鋼管(guan)(guan)(guan)(guan)是(shi)圓(yuan)管(guan)(guan)(guan)(guan)。但是(shi)，圓(yuan)管(guan)(guan)(guan)(guan)也有(you)(you)(you)(you)一定的(de)(de)局限性，如(ru)在受平面(mian)彎曲的(de)(de)條件下，圓(yuan)管(guan)(guan)(guan)(guan)就不(bu)如(ru)方、矩形(xing)管(guan)(guan)(guan)(guan)抗(kang)彎強度大，一些農機具骨架(jia)、鋼木(mu)家具等(deng)(deng)就常用(yong)方、矩形(xing)管(guan)(guan)(guan)(guan)。根據不(bu)同(tong)用(yong)途還(huan)需(xu)有(you)(you)(you)(you)其他截(jie)(jie)面(mian)形(xing)狀(zhuang)的(de)(de)異(yi)(yi)型鋼管(guan)(guan)(guan)(guan)。
