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(jí)。主要用于采暖、通風(fēng)、空調(diào)用汽、工業(yè)用氣。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(duì)各種保溫材料的導(dǎo)熱系數(shù)，不能簡(jiǎn)單地以廠家提供的單體數(shù)值為準(zhǔn)，而應(yīng)搞清楚該數(shù)值是在何種溫度、何種條件、哪一級(jí)檢測(cè)部門測(cè)定的，有否導(dǎo)熱系數(shù)方程式的條件下，然后盡量參照行業(yè)標(biāo)準(zhǔn)確定的導(dǎo)熱方程式來選取、確定導(dǎo)熱系數(shù)。例如微孔硅酸鈣，筆者見過幾個(gè)廠家標(biāo)出的導(dǎo)熱系數(shù)都不同，這時(shí)應(yīng)憑據(jù)標(biāo)準(zhǔn)《硅酸鈣絕熱制品》的相關(guān)條文選取，送樣檢測(cè)后確定導(dǎo)熱系數(shù)。廣州鋁合金管道安裝公司化工管道腐蝕泄漏修復(fù)方法就是補(bǔ)焊、打卡子或者做管箍、更換密封件、密封膠堵漏等方式。</p><div

style="text-indent:25px">氣體管道包括控制閥門、過濾器、減壓裝置、壓力表、流量計(jì)、在線分析儀等，宜集中設(shè)在氣體入口室。氣體經(jīng)鼓風(fēng)機(jī)、壓縮機(jī)、泵和鍋爐等增壓后，從管道的高壓處流向低壓處，也可利用氣體自身的壓力或重力輸送。當(dāng)氣體的流量已知時(shí)，管徑的大小取決于允許的流速或允許的摩擦阻力(壓力降)。流速大時(shí)管徑小，但壓力降值增大。但泵和壓縮機(jī)等動(dòng)力設(shè)備的運(yùn)行能耗費(fèi)用增大。此外，如果流速過大，還有可能帶來一些其他不利的因素。因此管徑應(yīng)根據(jù)建設(shè)投資、運(yùn)行費(fèi)用和其他技術(shù)因素綜合考慮決定。 </p><p style="text-indent:25px">近年來，隨著氧氣用量的增加，用氧大戶都采用氧氣管道輸送。由于管路長(zhǎng)，分布廣，再加上急開或速閉閥門，造成氧氣管道和閥門燃燒的事故時(shí)有發(fā)生，所以，較全分析氧氣管道和冷門存在的隱患、危險(xiǎn)，并采取相應(yīng)的措施是至關(guān)重要的。管道內(nèi)的鐵銹、粉塵、焊渣與管道內(nèi)壁或閥口摩擦產(chǎn)生高溫發(fā)生燃燒。.管道內(nèi)或閥門存在油脂、橡膠等低燃點(diǎn)的物質(zhì)，在局部高溫下引燃。氧氣管道和閥門在高壓純氧中，其危險(xiǎn)性是非常大的，試驗(yàn)證明，著火的點(diǎn)爆能與壓力平方成反比，這些對(duì)氧氣管道和閥門構(gòu)成了極大的威脅。壓力管道是一個(gè)系統(tǒng)，相互關(guān)聯(lián)相互影響，牽一發(fā)而動(dòng)全身。</p><div
