class="box"><p><p style="text-indent:25px">蒸汽管道是熱力管道的一種，需要GB2施工資質(zhì)，熱力管道是屬于壓力管道的一類，GB2級。主要用于采暖，蒸汽管道安裝施工、通風、空調(diào)用汽、工業(yè)用氣，蒸汽管道安裝施工。蒸汽管道又分為飽和蒸汽管道（壓力PN小于等于1.6MPa）和過熱蒸汽管道（壓力PN小于等于1.6MPa，溫度t小于300攝氏度）。蒸汽管道（直埋蒸汽管道）對各種保溫材料的導熱系數(shù)，不能簡單地以廠家提供的單體數(shù)值為準，而應(yīng)搞清楚該數(shù)值是在何種溫度、何種條件、哪一級檢測部門測定的，有否導熱系數(shù)方程式的條件下，然后盡量參照行業(yè)標準確定的導熱方程式來選取、確定導熱系數(shù)。例如微孔硅酸鈣，蒸汽管道安裝施工，筆者見過幾個廠家標出的導熱系數(shù)都不同，這時應(yīng)憑據(jù)標準《硅酸鈣絕熱制品》的相關(guān)條文選取，送樣檢測后確定導熱系數(shù)。空壓管道有***的鋁合金材質(zhì)。蒸汽管道安裝施工</p><div

style="text-indent:25px">氧氣管道要經(jīng)常檢查維護，除銹刷漆，每3～5年一次。管路上的安全閥、壓力表，要定期校驗，1年1次。完善接地裝置。動火作業(yè)前，應(yīng)進行置換，吹掃，吹出氣體中氧含量在18％～23％時為合格。閥門、法蘭、墊片及管材、管件選用應(yīng)符合《深度冷凍法生產(chǎn)氧氣及相關(guān)氣體安全技術(shù)規(guī)程》（GB16912-2008）的有關(guān)規(guī)定。建立技術(shù)檔案，培訓操作，檢修，維護人員。開關(guān)氧氣閥門時應(yīng)緩慢進行，操作人員應(yīng)站在閥門的側(cè)面，開啟要一次到位。嚴禁用氧氣吹刷管道或用氧氣試漏、試壓。</p><p style="text-indent:25px">從廣義上理解，壓力管道是指所有承受內(nèi)壓或外壓的管道，無論其管內(nèi)介質(zhì)如何。壓力管道是管道中的一部分，管道是用以輸送、分配、混合、分離、排放、計量、控制和制止流體流動的，由管子、管件、法蘭、螺栓連接、墊片、閥門、其他組成件或受壓部件和支承件組成的裝配總成。對壓力管道的檢驗檢測工作包括：外觀檢驗、測厚、無損檢測、硬度測定、金相、耐壓試驗等。而磁粉檢測則是無損檢測一種經(jīng)常使用的方法。磁粉檢測的能力不*與施加磁場強度的大小有關(guān)，還與缺陷的方向、缺陷的深寬比、缺陷的形狀、工件的外形、尺寸和表面狀態(tài)及可能產(chǎn)生缺陷的部位有關(guān)。因此就有各種不同的磁化方法。常用鋁及鋁合金管鋁管的較高運用溫度不得超越200℃。</p><div
