Is there any strength in straightening the deformed round tube?
Yes Straightening of deformed circular tube increases the ability to bear impact load. In order to eliminate the internal stress of steel pipe and improve the service strength of straight seam steel pipe, various mechanics are adopted, including strength, plasticity, toughness and work hardening, so straightening deformed circular pipe is strong. The straightening of deformed circular tube can be realized by manual straightening. Fix one end of the steel pipe, with the bending radian upward, and put a point below the middle of the bending radian, indicating that the steel pipe is horizontal or slightly higher. Press the other end hard to straighten the deformed round tube.
