Inelastic analysis of dissimilar metallic pipe joints for CRBRP application

Conference ·
OSTI ID:5335888
A preliminary inelastic analysis of a dissimilar metallic transition joint was made based on the piping design specification for CRBRP applications. The transition joint was analyzed to satisfy the elevated temperature ASME Code requirements. The transition joint analyzed is a tri-metallic joint composed of 316 stainless steel, alloy 800H, and 2-1/4 Cr-1Mo steel sections. The preliminary results from this analysis showed that the plastic deformation occurs predominantly in the alloy 800H section, while the accumulated inelastic strain due to creep is much more significant in the 2-1/4 Cr-1Mo section. The region of this transition joint which experiences the greatest amount of accumulated damage is at the interface of the 2-1/4 Cr-1Mo steel and the Inconel 82 weldment.
