Hi all

I am working on CS pipe which is coaated with FBE (Fusion bonded Epoxy). Line size is 20" sch 80. Temp = 95C Pressure is 224 bars.
I would like to know what is the limitation for expansion in loops. My concern is to make sure that my coating is not going to tear because of too much expansion at bends. Total run of this line is 3KM.

Please give you expert comments. It is urgent

Thanks
