My expanion joint material is SA 240 316 and Shell material is API 5L Gr. B
and tubebundle is of material SA 213 TP 316L.

This expansion joint fails when i design it in my software. Errors are related to its failiure in bending and at flued portion i.e. weld joint locations at shell inteconnections.

This is an issue now, because this exchanger is in operations.

Also i want to understand that in such component designing what are general recommendations for following conditions?

a) Cycles to be used in analysisb) Flange and Flued joint design thickness limitations
c) Thin walled joint design thickness limitations
d) Which type of expansion joints are relatively better for BEM type exchanger.

Best regards,
Osama
