Design, development and qualification of a titanium to SS joint with groove

Design, development and qualification of a titanium to SS joint with groove An improved lap type diffusion-bonded transition joint was developed between titanium (Ti) pipe and stainless steel (SS) pipe with grooves at the interface for use in high pressure-high temperature applications. The groove design was optimised using finite element method (FEM) so as to produce joint strength superior to the strength of the Ti pipe being joined. Elastic­plastic FE analyses were performed simulating large displacement and deformation involved. Further, joints were subjected to a simplified pull-out test to assess its strength. A good matching of joint strength, within 10% of FEM prediction and experimental results has been achieved. Design curves were generated using non dimensional parameters like r/t and a1/t (r-pipe radius, t- pipe thickness and a1-groove depth) to arrive at the groove depth for r/t range of 10, 15 and 20.

Abstract

An improved lap type diffusion-bonded transition joint was developed between titanium (Ti) pipe and stainless steel (SS) pipe with grooves at the interface for use in high pressure-high temperature applications. The groove design was optimised using finite element method (FEM) so as to produce joint strength superior to the strength of the Ti pipe being joined. Elastic­plastic FE analyses were performed simulating large displacement and deformation involved. Further, joints were subjected to a simplified pull-out test to assess its strength. A good matching of joint strength, within 10% of FEM prediction and experimental results has been achieved. Design curves were generated using non dimensional parameters like r/t and a1/t (r-pipe radius, t- pipe thickness and a1-groove depth) to arrive at the groove depth for r/t range of 10, 15 and 20. It was demonstrated experimentally that the joint with groove performs better under thermal cycling loads.
