We had proposed a creep life assessment method for boiler piping that can consider the heat-to-heat variations of the creep properties of each welded joint, where the creep properties of the welded joint are estimated from those of each base metal. I

The effect of taking a miniature sample scoop on the creep life of ASME Grade 91 (9Cr steel) piping was experimentally assessed. Internal pressure tests were conducted at 650oC on tubular specimens of virgin and long-term used 9Cr steels having scoop

Creep strength-enhanced ferritic (CSEF) steels are widely used in fossil power plants operated in many countries and life management for the components made of these materials are of critical importance for plant operators. In particular, failures in

Type IV creep damage has been frequently reported in longitudinal welds and nozzle welds. Many studies have been conducted on the longitudinal welds, and the applicability of life evaluation by non-destructive testing and numerical analysis has been
