********I’m working on the piping system connected to a 20” pump nozzle and the designer put an expansion joint after the pump nozzle and a line stopper after the expansion joint.*********

Dear Clyde

As per your initial question.
Yes it is quite usual practice of some good companies for cooling water line.
I guess you also handling cooling water system.

1)Do not forget to use Tied bellow.
2)Just after bellow put rest+guide+limit stop
3)You can not model this system in Caesar & justify
4)It is assumed that tied bellow with gasket flexibility will take care of small amount of thermal expansion between bellow & limit stop
5)This is not accepted for line with considerable temperature
