Abstract

During inspection of a heating coil in the convection section of a steam reformer, significant thickness loss due to external corrosion was discovered in a large number of tubes. In order to optimize the scope of repairs and ensure further safe operation, a level 3 fitness-for-service and remaining life analysis were performed in accordance with API-579. This paper will describe the fitness-for-service assessment that was performed, first using an idealized geometry, and thereafter using the actual corroded geometry of a removed tube. The procedure used to estimate the remaining life of the damaged coil will also be presented.
外腐蚀对流盘管的适用性评定
在对蒸汽转化炉对流段加热盘管的检查中,发现大量管由于外部腐蚀而造成严重的厚度损失。为了优化维修范围并确保进一步的安全运行,根据API-579进行了3级服务适用性和剩余寿命分析。本文将描述所进行的适用性评估,首先使用理想的几何形状,然后使用取出的管的实际腐蚀几何形状。还将介绍用于估计损坏线圈剩余寿命的程序。
