摘要
大庆石油化工总厂化工厂苯乙烯车间TT-201进料蒸发预热器,由于氢腐蚀、垢下腐蚀和湍流腐蚀,致使换热管泄漏。文章对腐蚀机理进行了分析,并提出了相应的解决措施。
The heat exchange tube of TT 201 heat exchanger in styrene plant of Daqing Petro- chemical Works leaked from hydrogen corro- sion,fouling corrosion and turbulent flow corro- sion.In this article the corrosion mechanism is analyzed and the relative solution is brought for- ward.
