The Analysis of Corrosion Failure for the Second Heat - Evaporator

本文对尿素生产中二段蒸发加热器管束腐蚀失效的原因进行了分析,表明造成二段蒸发加热器腐蚀失效的主要原因为冲刷腐蚀,并且提出了解决的方法.

This paper desicribes something about the second heat-evaporator tube-bundle corrosion failure of the carbamide-producation. The corrosion is the impingement-attack.It gives a way of corrosion protection.
