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，廣州管道管道改造。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
