為什么管道要做保溫 鐵皮和鋁皮有什么區別

不是所有(you)的(de)材(cai)料(liao)(liao)都可以(yi)用在保溫(wen)工程中，對(dui)此，我鐵皮保溫(wen)施工隊有(you)嚴格的(de)要(yao)求和界限，所使用的(de)保溫(wen)材(cai)料(liao)(liao)必須具有(you)合格證和出廠證明，并且要(yao)出示(shi)相關部門的(de)認證、相關部門的(de)檢測證明，保溫(wen)材(cai)料(liao)(liao)的(de)技術(shu)參數和防(fang)火(huo)級別要(yao)達到相關要(yao)求，例如(ru)：導熱系數為0.042～0.064W/m·K（巖棉板或氈(zhan)）、導熱系數為0.022～0.047W/m·K；（玻璃棉板或氈(zhan)）等。 
拆除原保護層(ceng)(ceng)保溫(wen)層(ceng)(ceng)—-中(zhong)間(jian)檢(jian)查(cha)――安裝巖棉管殼50㎜—-中(zhong)間(jian)檢(jian)查(cha)――安裝鍍鋅鐵皮(pi)0.5㎜—-竣工驗收； 
每道工(gong)序施工(gong)隱蔽(bi)前要經甲方質檢人員(yuan)檢查(cha)驗(yan)收(shou)，做好(hao)表面干凈、無(wu)灰塵、無(wu)油污等，每一道油漆(qi)必(bi)須(xu)采用漆(qi)膜(mo)測厚儀測干膜(mo)厚度，防腐完工(gong)后組(zu)織竣工(gong)驗(yan)收(shou)。 
管(guan)道保(bao)(bao)溫(wen)施工(gong)均(jun)按設(she)計的材質及(ji)保(bao)(bao)溫(wen)厚(hou)度進(jin)行。管(guan)道保(bao)(bao)溫(wen)先鋪設(she)保(bao)(bao)溫(wen)管(guan)殼本工(gong)程(cheng)(cheng)蒸汽管(guan)道保(bao)(bao)溫(wen)采用(yong)(yong)硅酸(suan)鋁纖維(wei)制(zhi)品，然后(hou)(hou)用(yong)(yong)鍍鋅(xin)鐵(tie)(tie)絲(si)將管(guan)殼綁(bang)扎牢固，每(mei)層材料(liao)都用(yong)(yong)鍍鋅(xin)鐵(tie)(tie)絲(si)綁(bang)扎，每(mei)塊保(bao)(bao)溫(wen)材料(liao)不少于兩道雙股(gu)鐵(tie)(tie)絲(si)，保(bao)(bao)溫(wen)材料(liao)鋪設(she)時要錯縫壓縫。主保(bao)(bao)溫(wen)層鋪設(she)結束后(hou)(hou)進(jin)行外(wai)護層的施工(gong)，外(wai)護層采用(yong)(yong)金(jin)(jin)屬外(wai)護，本工(gong)程(cheng)(cheng)采用(yong)(yong)厚(hou)度為0.5mm的鋁合(he)金(jin)(jin)板。金(jin)(jin)屬外(wai)護下料(liao) 
加(jia)工(gong)需一(yi)套白鐵加(jia)工(gong)機(ji)械(xie)。為確(que)保(bao)(bao)工(gong)程(cheng)質量我們準備(bei)新購置一(yi)套白鐵加(jia)工(gong)機(ji)械(xie)，以確(que)保(bao)(bao)保(bao)(bao)溫外護加(jia)工(gong)美觀(guan)。管道(dao)彎(wan)頭(tou)加(jia)工(gong)成(cheng)蝦米彎(wan)形(xing)式，閥門(men)制成(cheng)一(yi)保(bao)(bao)溫盒，既美觀(guan)又拆(chai)卸方便。 
外護固(gu)定采用抽芯(xin)鋁鉚釘，間距200mm左右。柏靼好的金屬外護層要做到牢固(gu)、美觀、防水
