Sažetak
Centrifugally cast materials, namely HK40, HP Modified, and Micro-Alloy materials, are used for tube materials in steam reformer tubes. The material undergoes various stresses resulting in damage which can manifest itself in several ways. Non-destructive testing (NDT) plays an essential role on maintenance program to assure operation of industrial plants. Proper determination of tube condition and its remaining life requires specific in-site examinations. The combination of techniques provides valuable date for the prediction of the remaining life of tubes, what is in article shown. Metallurgical examination of tubes removed from such service has been examined and also in paper shown. All mentioned parameters and results could be useful by tube repair welding planning and performing. Field experiences and findings are discussed in the paper.
