常压塔顶汽油换热器管束故障频繁 ,一直是困扰我厂平稳生产的主要问题之一 ,几年来 ,我们曾经采用过碳钢芯子 ,1 2 Cr2 AIMOV芯子 ,管子内壁涂镀 PVC耐腐蚀材料 ,以图增加管束的使用寿命 ,但实际使用效果均不是很理想。本文结合工艺生产的数据及换热器使用状况对各种制造工艺、
Atmospheric pressure overhead gasoline heat exchanger tube bundle failure has been plagued the smooth production of our plant one of the major problems, the past few years, we have used carbon steel core, 1 2 Cr2 AIMOV core, the inner tube coated with PVC resistance Corrosion materials, in order to increase the service life of the tube bundle, but the actual use of results are not very satisfactory. This article combines the process of production data and the use of heat exchanger on a variety of manufacturing processes,
