Abstract：Flattening and reverse bending straightening is an effective way to improve the straightening precision of small cross section tube. As the flattening amount was not easy to determine during tube straightening process, a three-dimensional finite element model of two-roller straightening process of tubes was established using finite element software. The variations of contact length, residual stress, straightening force, straightness and ovality under different flattening amount have been studied. It has been found that the reasonable value range of flattening amount is 0.4－0.7 mm. Using the value range to adjust the roll gap can get a good straightening effect in the field experimentation, and reduces the time of adjusting the roll gap.
