蒸汽转化炉管必须在操作过程中承受高温和压力，并由离心铸造材料制成，通常是HK-40、HP改性和微合金材料。由于运行条件可能导致各种形式的损伤，为了准确预测管道寿命，损伤的识别和量化是至关重要的。本文描述了检测系统的最新发展，该系统使用多种无损检测技术来提供对当前管道状况的最全面的评估。再加上复杂的剩余寿命评估软件模型，该模型不仅可以预测炉子中每根管子的剩余寿命，还可以计算未来运行条件变化对管子老化的影响。文中还讨论了现场经验和调查结果。©2010美国化学工程师学会流程SAF Prog，2010
Steam reformer tubes must withstand high temperature and pressures during operation and are made from centrifugally cast materials, typically HK‐40, HP modified, and microalloy materials. As operating conditions can result in various forms of damage, the identification and quantification of damage is of vital importance if tube life is to be predicted accurately. This article describes the recent developments in an inspection system, which uses multiple nondestructive testing techniques to provide the most comprehensive assessment of current tube condition. This is coupled with a sophisticated remaining life assessment software model, which not only predicts the remaining life of each tube in a furnace but can also calculate the effect of changes in future operating conditions on tube ageing. Field experiences and findings are also discussed in the article. © 2010 American Institute of Chemical Engineers Process Saf Prog, 2010
