6、、紧凑、流体阻力小，可制造较大换热面积。但耐压、耐温较块孔式低，不适用于强烈冲击、振动的场合，并以作冷却（冷凝）器为好。   本设备分I型和和Ⅱ型。I型不带气液分离器，Ⅱ型带气液分离器，作冷凝器时应选用Ⅱ型。   浮动端管板的密封在直径小于500毫米时，可用O形橡胶密封圈，一般用盘根密封。   技术特性   (按HG5-1320-80)   许用温度作加热器：-20~120℃作冷却器：-20~130℃许用压力管程：0.1~02MPa壳程：0.3MPa   注：我厂生产两种系列的浮头列管式换热器：1)按化工部标准HG5-1320-80制造的GH型

7、;2)按1967年化工院图纸制造老系列，LGH型(1982年前产品按此型制造)用户可任意选用，并可按用户来图制造或根据用户需要代为设计。目前一般生产的是由ф22/ф32毫米、ф36/ф50毫米石墨管组装的列管式石墨换热器。   产品最大规格210米2/台。 产品参数：GH型列管式石墨热器系列表筒体直径毫米管数根有效管长2000毫米3000毫米4000毫米500毫米公称内径外径平均公称内径外径平均公称内径外径平均公称内径外径平均3003855.37.66.5107.911.49.7--------40061108.512.210.31512.61
