Thanxs for your replies.

It is not an axial displacement..

See. I have provided a Guide with 10 mm before and after the loop.

So the pipe can move laterally 10 mm. The bend starts at 5500mm from the Guide. Where i am getting around 17mm lateral displacement in the centre node of bend and 39mm lateral displacement in the To node of bend.

The bend is pulling off by the loop. Is it reality?
