چکیده
|
Post weld heat treatment (pwht) is a necessary method in the welded pressure vessels to increase the mechanical/metallurgical properties. in the current investigation, creep buckling analysis of a vertical pressure vessel made of sa-516 g70 during local post weld heat treatment at 650℃ by isochronous stress strain curve obtained by omega method based on api 579-1/asme ffs-1 is presented.
