Richard,

Thanks for your response,
I have same Idea with you to add second expansion joint into horizontal pipe, and seems It works , but unfortunately node 140 could not be shifted so the turbine nozzle still over loaded. than I try to add spring near the 45 bend and near the reducer and make some adjustment on it. with this configuration I can safe the turbine, but ofcourse the cost will be expensive.

would you please to advise, to make my system more simple

Regards,
WINDU
