style="text-indent:25px">蒸汽管道的設(shè)計(jì)一般蒸汽管道應(yīng)該布置在管廊額一側(cè)。在高溫的情況下，蒸汽管道會(huì)膨脹，在這個(gè)時(shí)候就可以利用π形補(bǔ)償器吸收管道的熱膨脹。由于波紋管膨脹節(jié)價(jià)格比較貴，使用的壽命也不長(zhǎng)，因此在蒸汽管道熱膨脹的時(shí)候一般不使用它進(jìn)行吸收。在確定補(bǔ)償器的安裝位置的時(shí)候，首先要嚴(yán)格的分析管道，使補(bǔ)償器能夠得到集中的設(shè)置。在外側(cè)設(shè)置的一般都是那些溫度比較高和補(bǔ)償量比較大的管道，而內(nèi)側(cè)設(shè)置的是相應(yīng) 的溫度比較低和補(bǔ)償量比較小的管道。π形補(bǔ)償器一般設(shè)置在中間的位置，另外要設(shè)置導(dǎo)向架在補(bǔ)償器的兩側(cè)，根據(jù)管道的應(yīng)力來(lái)確定導(dǎo)向架和補(bǔ)償器之間的距離。在計(jì)算支架的推力和蒸汽管道的應(yīng)力的時(shí)候，要計(jì) 算整個(gè)蒸汽管道的應(yīng)力。一般在化工裝置中都設(shè)置的有多層的管廊，而在多層管廊的上層設(shè)置的是蒸汽管道，這樣可以使低溫管道和液態(tài)烴管道不相鄰。在同一層上，可以同時(shí)的布置蒸汽管道和電子儀表電纜，但是要保證兩者的間隔不能小于200mm。也可以將蒸汽管道布置在電子儀表電纜的下層，但間隔也不能小于500mm 。壓力管道有架空、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。惠州氨氣管道設(shè)計(jì)公司</p><p style="text-indent:25px">氣體管道可能承受許多種外力的作用。深圳氦氣管道施工工程</p><p
