ABSTRACT:
A method of forming a permanent curve in a length of convoluted wire-reinforced flexible plastics tubing comprises the steps of first flexing the chosen region of the tube into a curve whose radius is tighter than that eventually desired; forcibly holding said region in said tighter than desired curves; applying to the tube an internal pressure which is insufficient to burst the tube but which is high enough to strain the wire-reinforcement, the tube material, or both, in the bend region beyond its or their elastic limit; maintaining said internal pressure for a finite period of time; releasing the pressure; and finally releasing the tube from its preheld curve.
