316L不銹鋼(gang)(gang)(gang)無(wu)縫管(guan)(guan)(guan)是一種(zhong)(zhong)具(ju)有中(zhong)空(kong)截(jie)面(mian)(mian)、周邊沒有接縫的(de)(de)(de)長(chang)(chang)條(tiao)鋼(gang)(gang)(gang)材(cai)(cai)。鋼(gang)(gang)(gang)管(guan)(guan)(guan)具(ju)有中(zhong)空(kong)截(jie)面(mian)(mian),大(da)(da)量用(yong)作輸(shu)(shu)(shu)送流體(ti)的(de)(de)(de)管(guan)(guan)(guan)道(dao),如輸(shu)(shu)(shu)送石(shi)油、天然氣、煤氣、水及(ji)某些(xie)固體(ti)物料的(de)(de)(de)管(guan)(guan)(guan)道(dao)等(deng)。鋼(gang)(gang)(gang)管(guan)(guan)(guan)與(yu)圓(yuan)鋼(gang)(gang)(gang)等(deng)實心鋼(gang)(gang)(gang)材(cai)(cai)相比,在抗(kang)彎(wan)抗(kang)扭(niu)強(qiang)度相同(tong)時(shi),重量較輕(qing),目(mu)前已廣(guang)泛用(yong)鋼(gang)(gang)(gang)管(guan)(guan)(guan)來(lai)制造。鋼(gang)(gang)(gang)管(guan)(guan)(guan)還是各(ge)種(zhong)(zhong)常規(gui)武器不可缺是一種(zhong)(zhong)經(jing)濟截(jie)面(mian)(mian)鋼(gang)(gang)(gang)材(cai)(cai),廣(guang)泛用(yong)于(yu)制造結構件(jian)(jian)和機械零件(jian)(jian),如石(shi)油鉆桿、汽車(che)傳動軸(zhou)、自行車(che)架(jia)以(yi)及(ji)建筑施工(gong)中(zhong)用(yong)的(de)(de)(de)鋼(gang)(gang)(gang)腳手架(jia)等(deng)。用(yong)鋼(gang)(gang)(gang)管(guan)(guan)(guan)制造環(huan)形(xing)(xing)零件(jian)(jian),可提高材(cai)(cai)料利用(yong)率,簡化制造工(gong)序,節約(yue)材(cai)(cai)料和加工(gong)工(gong)時(shi),如滾動軸(zhou)承套(tao)(tao)圈、千斤頂套(tao)(tao)等(deng),少的(de)(de)(de)材(cai)(cai)料,*管(guan)(guan)(guan)、炮(pao)筒等(deng)都要鋼(gang)(gang)(gang)管(guan)(guan)(guan)來(lai)制造。鋼(gang)(gang)(gang)管(guan)(guan)(guan)按橫截(jie)面(mian)(mian)積形(xing)(xing)狀的(de)(de)(de)不同(tong)可分為(wei)圓(yuan)管(guan)(guan)(guan)和異型管(guan)(guan)(guan)。由于(yu)在周長(chang)(chang)相等(deng)的(de)(de)(de)條(tiao)件(jian)(jian)下(xia)(xia),圓(yuan)面(mian)(mian)積最大(da)(da),用(yong)圓(yuan)形(xing)(xing)管(guan)(guan)(guan)可以(yi)輸(shu)(shu)(shu)送更多(duo)的(de)(de)(de)流體(ti)。此外,圓(yuan)環(huan)截(jie)面(mian)(mian)在承受(shou)內部或外部徑向壓力時(shi),受(shou)力較均勻(yun),因此,絕大(da)(da)多(duo)數鋼(gang)(gang)(gang)管(guan)(guan)(guan)是圓(yuan)管(guan)(guan)(guan)。但是,圓(yuan)管(guan)(guan)(guan)也(ye)有一定的(de)(de)(de)局限性(xing),如在受(shou)平面(mian)(mian)彎(wan)曲(qu)的(de)(de)(de)條(tiao)件(jian)(jian)下(xia)(xia),圓(yuan)管(guan)(guan)(guan)就不如方、矩(ju)形(xing)(xing)管(guan)(guan)(guan)抗(kang)彎(wan)強(qiang)度大(da)(da),一些(xie)農(nong)機具(ju)骨架(jia)、鋼(gang)(gang)(gang)木(mu)家具(ju)等(deng)就常用(yong)方、矩(ju)形(xing)(xing)管(guan)(guan)(guan)。根據不同(tong)用(yong)途(tu)還需有其他截(jie)面(mian)(mian)形(xing)(xing)狀的(de)(de)(de)異型鋼(gang)(gang)(gang)管(guan)(guan)(guan)。
