Squashed pipes

I’m trying to make some plumbing with pipes based on extruding a circle along a path as taken from http://www.math.sunysb.edu/~sorin/online-docs/blender/html/x3148.html

My result shows flat pipes, as the circle does not appear to correctly maintain its orientation along the path curve.

It should not flatten out in the middle like it does.

What am I doing wrong?

i made a curve like yours using the extrude and i don’t ahve any kinks

the curve seems to be a path curve change it for a bezier curve

another thing if you need some nice joints then use the spin function
make a search in this forum you’ll find many good articles on pipe
