管壳式循环水冷却器管束内漏的控制

管壳式换热器广泛应用于石油化工等装置,而管束内漏的风险却一直困扰着装置的长周期运行。针对循环水冷却器管束内漏,结合制造与修理及相关文献的案例,从设计、制造及使用等控制环节对固定管板式、浮头式及U形管式等管束的内漏进行了分析,为防止管束内漏的风险需要设计、制造及使用共同控制,并给出了合理的建议。

The tube shell type heat exchanger is widely used in petrochemical equipment, and the risk of leakage has plaguedlong period operation of the device. For circulating water cooler tube bundle of leakage, combined with the case of manufacturing and repair and related literature, fi＇om the control links of the design, manufacture and use, the leakage reasons are analyzed and discussed, such as the fixed tube-sheet, floating head and u-tube bundle. Preventing the tube bundle from leakage, the design, manufacture and use should be associatedas a trinity. Also the reasonable suggestions are given.
