Hi neveenleo and naren,

Thanks for your reply.

The result would realy vary from the principle of spring form my result. I was reffering to lifting-off of the line supported with spring can. I am expecting less hot loads than my cold load. Example I have a spring can with 26.8kg/mm with cold load of 2000kg, and when it operate it lifted off(PUMP SUCTION SEGMENT) my loads are now 2010kg. WHY????

Regards!
