style="text-indent:25px">潔凈工藝管道是生物制藥生產(chǎn)工藝系統(tǒng)重心部分的工程施工，對管材及其組成件材料的要求都很高，需要加強(qiáng)對該系統(tǒng)潔凈工藝管道焊接施工的檢查，通過規(guī)范的施工控制，滿足工藝標(biāo)準(zhǔn)和設(shè)計要求。對潔凈室工藝管道管材的要求：1) 純化水、注射用水和純蒸汽的管道應(yīng)是316L不銹鋼電拋光管，Ra 值 <0.5 mm；2) 管材需提供熔煉爐號、制造號、制造材料,熔煉爐號在安裝現(xiàn)場應(yīng)可見。嵌墻敷設(shè)的管道要設(shè)管卡固定、在管線轉(zhuǎn)折處，應(yīng)預(yù)留5-10mm凈空，供自然補(bǔ)償管路因熱漲冷縮引起的伸縮變化值。壓力管道，是指利用一定的壓力，用于輸送氣體或者液體的管狀設(shè)備，其范圍規(guī)定為較高工作壓力大于或者等于0，深圳真空系統(tǒng)管道施工，深圳真空系統(tǒng)管道施工.1MPa（表壓）的氣體、液化氣體、蒸汽介質(zhì)或者可燃、易爆、有毒、有腐蝕性，深圳真空系統(tǒng)管道施工、較高工作溫度高于或者等于標(biāo)準(zhǔn)沸點(diǎn)的液體介質(zhì)，且公稱直徑大于25mm的管道。當(dāng)壓力過小時減壓閥閥門開度加大，充分的得到了控制的要求。深圳真空系統(tǒng)管道施工</p><div

style="text-indent:25px">氣體管道工程安裝：通常，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，管徑的大小取決于允許的流速或允許的摩擦阻力(壓力降)。流速大時管徑小，但壓力降值增大。因此，流速大時可以節(jié)省管道基建投資，但泵和壓縮機(jī)等動力設(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。管道可能承受許多種外力的作用，包括本身的重量、氣體作用在管端的推力、風(fēng)雪載荷、土壤壓力、熱脹冷縮引起的熱應(yīng)力、振動載荷和地震災(zāi)害等。為了保證管道的強(qiáng)度和剛度，必須設(shè)置各種支(吊)架，如活動支架、固定支架、導(dǎo)向支架和彈簧支架等。支架的設(shè)置根據(jù)管道的直徑、材質(zhì)、管子壁厚和載荷等條件決定。固定支架用來分段控制管道的熱伸長，使膨脹節(jié)均勻工作；導(dǎo)向支架使管子僅作軸向移動。深圳真空系統(tǒng)管道施工蒸汽保溫管安裝應(yīng)用柔性寬吊帶起吊，并應(yīng)穩(wěn)起穩(wěn)放，嚴(yán)禁將管道直接推入溝內(nèi)。</p><div

style="text-indent:25px">壓力管道安裝工程的特點(diǎn)：1、技術(shù)性強(qiáng)。管道工程是技術(shù)性較強(qiáng)的現(xiàn)代工程。管道本身和所用的設(shè)備，要保證能在較高的壓力下，安全、連續(xù)地輸送易燃易爆的油和氣。陸上管道的工作壓力有的高達(dá)80千克力/厘米2以上，海洋管道的受壓力的性能甚至高達(dá)140千克力/厘米2。另外,各種油、氣的性質(zhì)不同，要使管道能滿足不同的輸送工藝要求。例如天然氣和原油的輸送管道要進(jìn)行脫硫或脫水等預(yù)處理，輸送易凝高粘原油的管道要進(jìn)行加熱或熱處理等。管道敷施的環(huán)境千差萬別,還要有針對性的處置措施,例如永凍土地區(qū)的隔熱，沙漠地區(qū)的固沙，大型河流的穿越或跨越，深海水下的穩(wěn)管等。這些技術(shù)問題都是十分復(fù)雜，需要多專業(yè)、多學(xué)科來綜合解決?，F(xiàn)代化的管道工程普遍應(yīng)用電子技術(shù)，具有很高的自動化水平，在管理上，實(shí)行集中控制和高效、可靠的管理，其技術(shù)性更強(qiáng)。2、嚴(yán)格性高。管道工程質(zhì)量必須嚴(yán)格達(dá)到設(shè)計和規(guī)范的要求。數(shù)千公里長的管道系統(tǒng)，在工況經(jīng)常變化的條件下，要長期、高效、安全地連續(xù)運(yùn)行，就要求管道隨時處于較佳運(yùn)行狀態(tài)壓力管道安裝。</p><p style="text-indent:25px">管道安裝會出現(xiàn)哪些問題?防腐和清洗。為防止土壤的侵蝕,地下金屬管道表面應(yīng)涂防銹漆或焦油、瀝青等防腐涂料,或用浸漬瀝青的玻璃布和麻布等包覆。埋在腐蝕性較強(qiáng)的低電阻土壤中的管道須設(shè)置陰極保護(hù)裝置,防止腐蝕。地面上的鋼鐵管道為防止大氣腐蝕,在表面上涂覆以各種防銹漆。各種管道在使用前都應(yīng)清洗干凈,某些管道還應(yīng)定期清洗內(nèi)部。為了清洗方便,在管道上設(shè)置有過濾器或吹洗清掃孔。在長距離輸送石油和天然氣的管道上,須用清掃器定期清理管內(nèi)積存的污物,為此要設(shè)置專用的發(fā)送和接收清掃器的裝置。易燃?xì)怏w(如乙炔、氫氣等)需要和其他氣體分開，單獨(dú)引入。</p><div
