The evaluation of pressure and thermal stresses in piping systems where sufficient piping flexibility can’t be found with suitable pipe routing, often leads to the implementation of expansion joints. These solutions in large bore, high temperature and pressure piping systems, in addition to being technically challenging, demanding a fair amount of expertise from the pipe stress engineer, if not handled carefully, can often also be quite expensive. For those reasons alone, resorting not to go with the use of expansion joints can be warranted, but what if there is no other way? Using CAESAR II pipe stress analysis program and following ASME B31 as well as EJMA codes, provides solid ground for a good technical solution, however commercial aspects need to be taken into account as well. The investigation reveals the reasons behind the search for best techno – economical method for the implementation of expansion joints in piping design.
