style="text-indent:25px">氧氣管道安裝：制氧站內(nèi)的氧氣管道、埋地的氧氣管道和管線上閥件較多的氧氣管道多采用先脫脂后安裝法;廠區(qū)管網(wǎng)和車間內(nèi)的配管，多數(shù)采用先安裝后脫脂法。在管線上有較多閥件的情況下，也可采取先沖洗后試壓的做法。除銹是保證氧氣管道安裝質(zhì)量的關(guān)鍵環(huán)節(jié)之一。氧氣管道、閥件、接頭等在安裝前要對接觸氧氣的表面進(jìn)行檢查，清理污垢、鐵銹和毛刺。除銹方法有酸洗、噴砂、機(jī)械除銹、手工刷除銹等。當(dāng)管道數(shù)量大時，以采取酸洗法較好，工序為：酸洗→水洗→中和→水洗與鈍化→干燥。酸洗后在管子外表面涂防銹底漆和面漆(焊口部位不涂)，以防返銹。壓力管道設(shè)計施工就選興鼎。氫氣管道安裝改造工程</p><p style="text-indent:25px">所有的管路、閥門、壓力表都由高質(zhì)量的不銹鋼構(gòu)成，并且都是標(biāo)準(zhǔn)配件。氫氣管道安裝改造工程</p><p style="text-indent:25px">氧氣管道的注意事項：氧氣管道應(yīng)盡量少設(shè)彎頭和分岔頭，工作壓力高于0.1MPa的氧氣管道彎頭，應(yīng)采取沖壓成閥型法蘭制作。分岔頭的氣流方向，應(yīng)與主管氣流方向成45°到60°角。在對焊凹凸法蘭中，采用紫銅焊絲作O型密封圈，是氧氣用法蘭抗燃性可靠的密封形式。氧氣管道應(yīng)有導(dǎo)電的良好裝置，接地電阻應(yīng)小于10Ω，法蘭間電阻應(yīng)小于0.03Ω。車間內(nèi)主要氧氣管道的末端應(yīng)加設(shè)放散管，以利氧氣管道的吹掃和置換，在較長的氧氣管道進(jìn)入車間調(diào)節(jié)閥前，應(yīng)設(shè)過濾器。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，分布廣，再加上急開或速閉閥門，造成氧氣管道和閥門燃燒炸裂的事故時有發(fā)生，所以，較全分析氧氣管道和冷門存在的隱患、危險，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，其危險性是非常大的，試驗證明，著火的點(diǎn)爆能與壓力平方成反比，這些對氧氣管道和閥門構(gòu)成了極大的威脅。氫氣管道安裝改造工程</p></p><br
