Abstract
SA213-T22 steel had been widely used in
petrochemical and power generation plants. But due to
prolonged service exposure in various conditions, these tubes have been ageing continuously and deteriorations of the materials cannot be avoided. This paper presents a case study of SA213 type-T22 alloy steel reheater tube that failed in a boiler of a power plant. The failed tube was investigated through visual examination, mechanical properties evaluation, and microstructural analysis to find the root cause of failure. The tube was found to fail by long term over-heating due to formation of thick oxide scale formation leading to creep.
