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(qiáng)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。</p><p 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、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，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。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。氣體管道的安裝方法有螺紋聯(lián)接：主要適用于小直徑管道。</p><div

于0.05kgf/cm2)以上的下降。此時系統(tǒng)壓力應(yīng)在0.25MPa(相當(dāng)于2.5kgf/cm2)以上。必要時可在系統(tǒng)出口處外接一個0.5級標(biāo)準(zhǔn)壓力表來讀取壓力變化數(shù)。在證實氣路系統(tǒng)有泄漏時，可用分段堵住或關(guān)閉氣路的方法來縮小漏氣發(fā)生的范圍。絕大多數(shù)的漏氣點(diǎn)都發(fā)生于氣路接頭處，而氣路閥件內(nèi)部的泄漏也時有發(fā)生，至于管路中間的泄漏，除了急轉(zhuǎn)彎處以外是很少見的。管路上的安全閥、壓力表，要定期校驗，1年1次。深圳鋁合金管道設(shè)計施工</p><p
