Abstract: This paper reviews the data needed to develop fatigue design rules for pressure vessels fabricated from heat-treated 2-1/4Cr-1Mo steel (SA-387, Grade 22, Class 2 plates and SA-336, Grade F22 ...

Abstract: Predicting the residual life of plant equipment that has been in service for 20 to 30 years or more is a major concern of many industries. This paper reviews the reasons for increased concern ...

Abstract: A methodology for assessing the remaining life of hot reheat steam pipe with longitudinal flaws, such as those typically associated with the longitudinal seam welds, has been developed. The ...

Abstract: This program was undertaken to develop isothermal low-cycle fatigue information for AISI 1010 steel in air. Such information is needed to help predict acceptable conditions for equipment and ...

Abstract: Some energy-system structural components may be subjected to 107 or more cycles of small-amplitude, strain-controlled vibrations. In such cases, information on the elevated-temperature, long-life ...

Abstract: Fatigue design criteria for pressure vessel steels are developed herein based on analysis of available material data between room temperature and 427 C (800 F). Strain-controlled low-cycle and ...

Abstract: This paper describes a model developed for computer simulation of stresses in heater tubes used in petrochemical service. The model predicts the damage to the tube material and thus provides ...
