What is take up when bending pipe?

Take-up in pipe bending refers to the amount of material that is shortened or lost in length due to the bending process. When a pipe is bent, it experiences deformation, which results in a change in the length of the straight section of the pipe. The take-up is important for ensuring accurate measurements and fitting of the pipe in its intended application, as it affects the overall dimensions and alignment. Proper calculations and adjustments for take-up help maintain the integrity and functionality of the bent pipe.
