style="text-indent:25px">氣體管道工程安裝：法蘭聯(lián)接。適用的管道直徑范圍較大。聯(lián)接時(shí)根據(jù)氣體的性質(zhì)、壓力和溫度選用不同的法蘭和密封墊片，利用螺栓夾緊墊片保持密封。在需要經(jīng)常拆裝的管段處和管道與設(shè)備相聯(lián)接的地方，大都采用法蘭聯(lián)接。承插聯(lián)接。主要用于鑄鐵管、混凝土管、陶土管及其聯(lián)接件之間的聯(lián)接，只適用于在低壓常溫條件下工作的給水、排水和煤氣管道。聯(lián)接時(shí)，一般在承插口的槽內(nèi)先填入麻絲、棉線或石棉繩，然后再用石棉水泥或鉛等材料填實(shí)，還可在承插口內(nèi)填入橡膠密封環(huán)，使其具有較好的柔性，容許管子有少量的移動(dòng)。焊接聯(lián)接。焊接聯(lián)接的強(qiáng)度和密封性較好，適用于各種管道，省工省料，但拆卸時(shí)必須切斷管子和管子聯(lián)接件?；葜輾錃夤艿涝O(shè)計(jì)壓縮空氣管道種類比較多，有鍍鋅管，碳鋼管，不銹鋼管等等。</p><div

style="text-indent:25px">壓力管道的作業(yè)一般都在室外，敷設(shè)方式有架空、沿地、埋地，甚至經(jīng)常是高空作業(yè)，環(huán)境條件較差，質(zhì)量控制要求較高。壓力管道作為危險(xiǎn)性較大的特種設(shè)備正式列入安全管理與監(jiān)察規(guī)定才2年，許多人對(duì)壓力管道安全意識(shí)淡薄。已發(fā)生的事故已經(jīng)給人們敲了警鐘，不能讓更多的事故再促人猛醒。就事故預(yù)防而言，我們還不能簡(jiǎn)單地就事故論事故，而必須給予文化高度的思考，即在觀念上確立文化意識(shí)，在工作中大力加強(qiáng)壓力管道的安全文化建設(shè)，通過安全培訓(xùn)，安全教育，安全宣傳，規(guī)范化的安全管理與監(jiān)察，不斷增強(qiáng)人們安全意識(shí)，提高職工與大眾安全文化素質(zhì)，這樣才能體現(xiàn)“安全一，預(yù)防為主”的方針，才能以嶄新的姿態(tài)開展新時(shí)期的安全工作。安全文化包括兩部分：一部分是人的安全價(jià)值觀，主要指人們的安全意識(shí)、文化水平、技術(shù)水平等；另一部分是安全行為準(zhǔn)則，主要包括一些可見的規(guī)章制度以及其他物質(zhì)設(shè)施，其中人的安全價(jià)值觀是安全文化較重心較本質(zhì)的東西。</p><p style="text-indent:25px">一、熱力管道的安裝要求有哪些？熱力管道通常采用架空敷設(shè)或地溝敷設(shè)。為了便于排水和放氣，管道安裝時(shí)均應(yīng)設(shè)置坡度，室外管道的坡度為0.002，室外管道的坡度為0.003，蒸汽管道的坡度應(yīng)與介質(zhì)流向相同，以避免噪聲。每段管道較低點(diǎn)要設(shè)排水裝置，較高點(diǎn)應(yīng)設(shè)放氣裝置。二、乙炔管道的安裝要求有哪些？乙炔管道宜采用焊接連接，小直徑高壓乙炔管也可采用高壓卡套式接頭，與設(shè)備、閥門、附件的連接，可采用法蘭或螺紋。世紀(jì)星介紹在管內(nèi)徑大于50mm的中壓乙炔管道上，不應(yīng)有盲板或死端頭，也不應(yīng)選用閘閥。三、氧氣管道的安裝要求有哪些？所用的管子、管件、閥門及墊片安裝前必須進(jìn)行徹底的脫脂處理。在安裝過程中應(yīng)隨時(shí)檢查，若被油脂污染，應(yīng)重新進(jìn)行脫脂處理后，方可繼續(xù)進(jìn)行安裝。壓力管道設(shè)計(jì)施工就選興鼎。</p><div
