Residual life assessment of a pipeline bend by using small punch creep tests

Popis výsledku v původním jazyce

Small punch creep test (SPC test) is an alternative and still developing method to conventional uniaxial creep test and as such can be used for obtaining information about the creep properties of steels and alloys even when only a limited amount of test material is available. SPC method has been also implemented into EN 10371 "Metallic materials – Small punch test method". SPC testing can also be used with advantage also for assessment of the residual life of critical components of fossil fueled power plants. The biaxial nature of the SPC tests differs considerably from the uniaxial conventional creep tests but it is possible to convert the equivalent SPC loading to the uniaxial creep stress on the basis of the equal test durations. Such an approach is demonstrated on the material of a pipeline bend after long-term exposition at 490 °C and the results are used for the assessment of the residual lifetime of this bend made of a 0.5Cr-0.5Mo-0.3V steel.
