If the material is steel or aluminum and the diameter isn't too large, you might be able to "cold straighten" it:
The Table Test: Lay the tube on a flat welding table or floor. Press one end flat. If the other end is lifting off the surface, that is your error.
The Lever Method: Secure one end in a heavy-duty vise (use soft jaws or wood blocks to protect the tube). Slide a longer, larger pipe over the other end to act as a lever, and gently twist until the two horizontal sections are coplanar.
