Hi petroleum community !

Just want to ask question about expansion joint connected to a pump.

So we have our pump, the expansion joint, few tube and a main anchor (all straight on - in one line (my english isn't that clear)).

Do we have to consider the thrust effect on the flange of the pump connection ?

I have read in "witzenmann book" that the pipe connection practically forces free and that the Reaction force absorbed by supports (main supports of the pump).

Thx for clearing my thoughts
