擎立生產(chǎn)的列管式換熱器是目前化工及酒精生產(chǎn)上應(yīng)用最廣的一種換熱器。它主要由殼體、管板、換熱管、封頭、折流擋板等組成。所需材質(zhì)，可分別采用普通碳鋼、紫銅、或不銹鋼制作.按形式分為固定管板式、浮頭式、U型管式換熱器，按結(jié)構(gòu)分為單管程、雙管程和多管程。傳熱面積0.5-500m2,可根據(jù)用戶需要定制。公稱直徑管程數(shù)管子數(shù)量換熱面積 公稱值/計(jì)算值管程通道截面積 管程通道流速為0.5m/sec時(shí)的流量m/hr公稱壓力管子長度（m）φ25×2.515002000300040006000φ25×21591141.5/1.622/2.173/3.27　　0.0044/0.00497.92/8.820.252191263/3.004/4.026/6.068/8.1　0.0082/0.009014.76/16.200.62263/3.004/4.026/6.068/8.81　0.0041/0.00457.38/8.011.02731445/5.087/5.1810/10.2614/13.7221/20.630.013812017955/0.015224.84/27.361.6　2405/4.626/6.199/9.3312/12.4719/18.760.0063/0.006911.24/12.422.53251607/6.939/9.2814/14.0019/18.7128/28.130.0188/0.020833.84/37.440.6　2566/6.479/8.6613/13.0517/17.4636/26.260.0088/0.009715.84/17.461.0
