Based on the analysis, made qualitative calculation of the various curvatures of the straightening process applying elastoplastic bending theory. The method of determining curvature of the inverted bending curvature of the axis of being straightened pipe is put forward with which straightening quality is guaranteed in the first place and solved the key problem that have not been solved for a long time. All of these provided theorial basis for the design of bending pipe straightening roller. and setting down of adjusting rule.
