無縫鋼管的生產制造方式和主要用途 無縫鋼管的(de)運用較(jiao)為普遍,關(guan)鍵是用于生(sheng)產制造水冷壁管(guan)(guan)、開水管(guan)(guan)、飽和蒸汽(qi)(qi)管(guan)(guan)、電力機車(che)加熱爐用的(de)飽和蒸汽(qi)(qi)管(guan)(guan),大(da)、小排(pai)風管(guan)(guan)及其拱磚管(guan)(guan)等。
而且在生產制造(zao)髙(gao)壓和(he)高壓加熱(re)爐的發(fa)電廠(chang)過熱(re)器管、再熱(re)器管、導支氣(qi)管、主管道等也(ye)可用上。
無縫鋼管主要用途很普遍。
一般主要用(yong)途(tu)的無縫鋼(gang)管(guan)由一般的碳素鋼(gang)、低(di)合金鋼(gang)或合金工具鋼(gang)冷(leng)軋,生產量(liang)多,關鍵作為運(yun)輸流體力學的管(guan)路或構造零(ling)件依據(ju)主要用(yong)途(tu)不(bu)一樣分三類(lei)供(gong)(gong)貨:a、按成(cheng)分和物理性能供(gong)(gong)貨;b、按物理性能供(gong)(gong)貨;c、按打壓試驗供(gong)(gong)貨。
按a、b類供貨的無縫鋼管,如用以承擔液(ye)體工作壓(ya)力,還要開展打壓(ya)試驗。
專業主要用(yong)(yong)途(tu)的無(wu)縫鋼(gang)管(guan)有加熱爐用(yong)(yong)無(wu)縫鋼(gang)管(guan)、化工廠(chang)電力工程用(yong)(yong),地(di)質(zhi)學用(yong)(yong)無(wu)縫鋼(gang)管(guan)及原(yuan)油用(yong)(yong)無(wu)縫鋼(gang)管(guan)等幾種。
無縫鋼管具備空心橫截面,很多(duo)作為運(yun)輸流體力學(xue)的管路,如運(yun)輸原(yuan)油、燃氣(qi)、液化(hua)氣(qi)、水(shui)及一些(xie)固態原(yuan)材料(liao)的管路等(deng)。
無縫鋼管與園(yuan)鋼等實(shi)芯(xin)不銹鋼板材(cai)對比,在抗(kang)(kang)彎強度(du)抗(kang)(kang)扭(niu)抗(kang)(kang)壓強度(du)同(tong)樣時,凈重偏輕(qing),是一(yi)種經濟發展(zhan)橫(heng)截面不銹鋼板材(cai)。
普(pu)遍用(yong)(yong)以(yi)生(sheng)產(chan)(chan)(chan)制造(zao)(zao)零部件和機械零件,如(ru)原油(you)鉆具、傳動軸、自行車(che)車(che)架及其建(jian)筑工(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)連用(yong)(yong)的(de)鋼鋼管腳手架等用(yong)(yong)無(wu)縫(feng)(feng)鋼管生(sheng)產(chan)(chan)(chan)制造(zao)(zao)環狀(zhuang)零件,可(ke)提升原材(cai)料使用(yong)(yong)率,簡單化生(sheng)產(chan)(chan)(chan)制造(zao)(zao)工(gong)(gong)(gong)藝流程(cheng),節省原材(cai)料和生(sheng)產(chan)(chan)(chan)加工(gong)(gong)(gong)綜合(he)工(gong)(gong)(gong)時,已(yi)普(pu)遍用(yong)(yong)無(wu)縫(feng)(feng)鋼管來生(sheng)產(chan)(chan)(chan)制造(zao)(zao)。
