家(jia)具管按規(gui)定壁厚(hou)有薄壁家(jia)具管和厚(hou)壁家(jia)具管兩種(zhong)
家(jia)具管(guan)(guan)(guan)(guan)結(jie)構(gou)作為(wei)新(xin)型的結(jie)構(gou)形式，直縫焊接鋼管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)形優異(yi)，壁厚均勻，性能優良，價格低(di)廉(lian)，具有廣闊的應(ying)用(yong)(yong)(yong)前(qian)景，為(wei)鋼結(jie)構(gou)行業(ye)和制管(guan)(guan)(guan)(guan)企業(ye)的發展帶(dai)來新(xin)的機(ji)遇，但在目前(qian)的推廣應(ying)用(yong)(yong)(yong)中(zhong)仍然有諸多的不利因素，需要(yao)用(yong)(yong)(yong)戶(hu)、設計單位、行業(ye)協會與(yu)生產(chan)廠家(jia)多方共同推動(dong)；需要(yao)進一步(bu)完(wan)善(shan)節點研(yan)(yan)究，加強高(gao)強鋼節點研(yan)(yan)究力(li)度，為(wei)高(gao)強鋼的廣泛使用(yong)(yong)(yong)開辟(pi)道路；家(jia)具管(guan)(guan)(guan)(guan)加工商需要(yao)盡快(kuai)完(wan)善(shan)結(jie)構(gou)鋼管(guan)(guan)(guan)(guan)標準(zhun)(zhun)體系，盡快(kuai)制定結(jie)構(gou)用(yong)(yong)(yong)直縫埋(mai)弧焊鋼管(guan)(guan)(guan)(guan)的標準(zhun)(zhun)；螺(luo)旋焊接鋼管(guan)(guan)(guan)(guan)本身存在安全隱患(huan)，在重要(yao)的鋼管(guan)(guan)(guan)(guan)結(jie)構(gou)場合中(zhong)應(ying)謹慎采用(yong)(yong)(yong)；研(yan)(yan)究采用(yong)(yong)(yong)級別更高(gao)的低(di)合金(jin)高(gao)強鋼或(huo)高(gao)鋼級管(guan)(guan)(guan)(guan)線鋼的可行性，以(yi)降低(di)工程造價。
家(jia)具管(guan)(guan)和無縫(feng)管(guan)(guan)在(zai)生產工藝(yi)上的區別在(zai)于，家(jia)具管(guan)(guan)是通(tong)過(guo)卷板開平然后通(tong)過(guo)電阻(zu)焊，或(huo)者(zhe)埋弧焊焊接而成(cheng)。有一條縱向的焊縫(feng)。而無縫(feng)家(jia)具管(guan)(guan)是通(tong)過(guo)把圓鋼熱軋或(huo)者(zhe)通(tong)過(guo)冷拔處理(li)做成(cheng)的。無縫(feng)家(jia)具管(guan)(guan)顧名思義沒(mei)有焊縫(feng)。
在(zai)實用(yong)(yong)方面家(jia)(jia)具(ju)管(guan)(guan)(guan)(guan)主要(yao)是(shi)用(yong)(yong)于低壓(ya)(ya)流(liu)(liu)體輸送， 低壓(ya)(ya)氣體輸送，和(he)礦山排水等(deng)(deng)等(deng)(deng)。的(de)材質主要(yao)是(shi)Q235A q235B等(deng)(deng)普通碳鋼。而無縫(feng)家(jia)(jia)具(ju)管(guan)(guan)(guan)(guan)的(de)承壓(ya)(ya)大于家(jia)(jia)具(ju)管(guan)(guan)(guan)(guan)所以一般用(yong)(yong)于高壓(ya)(ya)流(liu)(liu)體輸送，像氣瓶管(guan)(guan)(guan)(guan)，柴(chai)油機油壓(ya)(ya)管(guan)(guan)(guan)(guan)，另(ling)外(wai)還有(you)一部分(fen)作用(yong)(yong)于鋼結構方面，它(ta)的(de)主要(yao)材質又20#鋼 45#鋼和(he)16Mn等(deng)(deng)等(deng)(deng)。 家(jia)(jia)具(ju)管(guan)(guan)(guan)(guan)主要(yao)依靠三個(ge)方面的(de)技術(shu)進步 家(jia)(jia)具(ju)管(guan)(guan)(guan)(guan)技術(shu)的(de)發(fa)展(zhan)是(shi)伴(ban)隨著與無縫(feng)管(guan)(guan)(guan)(guan)而進步的(de)。
