I am still confused about your situation , but on my own understanding... your pipe route is from a guide, then 5.5m is the first elbow of your loop? then the bend displaced 17mm laterally, of course this is possible... take note that you have 10mm gap at the guides (5.5m away from the elbow), the pipe is not that rigid to have a max disp of 10mm to the 5.5m distance (plus this is a loop location)... then, the "to node" of the bend should be displacing more due to thermal/pressure, which is probably because the bend direction is the same direction of the displacements. (show/attach a simple sketch to have clarity on your inquiry)


Goodluck!
