摘要
剖析了苯乙烯装置原进口乙苯 /蒸汽过热器的失效原因 ,并提出了解决问题的技术措施 ,即通过合理选材避免了材质的高温回火脆化 ;改进滑动管板结构 ,使滑动管板易于滑动。
In this paper the factors causing the failure of the imported ethylbenzene/steam superheater in styrene plant of Qilu Petrochemical Corp.are analysed and the quick fix is proposed.The high temperature temper embrittlement was prevented by a rational material selection and the stress in the tube sheet was considerablely reduced by improving its design for ease to slide.The commercial pratice proved the improvements successful.
