Bellow type expansion joint design
(OP)
Which are the main differences in designing bellow type expansion joint according to EJMA or ASME. The application is on a double pipe heat exchanger ASME code designed and constructed. Thanks for your help.

ASME/TEMA gives guidelines for thick bellow design.

PS:
Always take the shipping brackets off after installation prior to using the equipment.

The stress equations in Appendix 26 are essentially the same as in EJMA. The fatigue equation in Apendix 26 is more conservative as it is a design equation with safety factors, whereas the EJMA fatigue curve is based on average data. The stress limits are different, and the more recent EJMA editions have added a number of equations dealing with limit load and stability failure modes, which are not found in the current Section VIII rules.
