If the Italian company is your consortium partner and takes ultimate responsibility for design of the plant including performance guarantee, you may rest in peace. However, in case you have to shoulder the responsibility of performance guarantee then I revert back to my previous mail. Analyze the system for seismic conditions, pass on the load to turbine manufacturer and let him decide if same is acceptable. As a quick reference, you can yourself perform stability check for turbine and have an idea if your loads are in the acceptable zone.

By the way, IRAN must be in a high seismic zone. I am interested to know what seismic factor you have used in your calculation.

One last thing: as pointed out by Paul, please refrain from off-list communication. The whole idea of piping group would be lost if information is not shared with others.

.

Dear sir;
thanks for your attention.
I'm working on petorchmical plant in south of Iran and our partner in this project is an Italin Co.
in this project we have some compressor& turbine. I calculte seismic acceleration from UBC code and consider that for calculating of occasional load on structure and nozzel, and sent Caesar file to our partner;then they answer to us ; we shall consider UBC Code for calculation of seismic acceleration and use this acceleration only for load on support and structure and it is'n necessrly consider that for load on nozzle during seismic. I want to know; is it correct?
and in which Code or vendor instruction this matter was written. also, others company's proceduer is like this not?

best regards
a.noori
