用戶要依據介質特性，然后從利于換熱，降低設備腐蝕，減小壓力降和清洗維護簡單這幾個方便來進選擇。那么選擇好了換熱器倆種介質誰走管程誰走殼程又成了大家關注的重點，其實大部分的管殼式換熱器上面都是會標出介質的方面和那個管道走什么介質，不過也有的廠家不會標出，所以小編就來給大家解答這個問題。江西換熱機組廠家可能會腐蝕管殼式換熱器的流體經過管程，因其經過殼程可能會使得換熱設備的管程與殼程都被介質腐蝕；包含有毒物質的流體經過管程，這樣一來就不會往外滲漏。供應換熱機組水壓較(jiao)高的流(liu)體(ti)經(jing)過(guo)管程(cheng)，可以防止設(she)備因(yin)為壓力過(guo)大(da)，所以去加厚管壁，造成材(cai)料浪(lang)費(fei)，資金投入增多；
