Let been processed into finished Seamless eccentric reducer having a smaller degree of curvature had to rely on machine tools straightening machine to complete. So in order to eliminate Seamless eccentric reducer bend, all Seamless eccentric reducer need to go through the cold straightening.

       Seamless eccentric reducer mill bent due to improper adjustment, residual stress and residual rolling along the tube due to the length of the cooling section and unequal causes. Therefore, it is impossible to get it straight pipe directly from the mill, just straight tubes by cold bending of the school to meet the prescribed technical conditions.

       The basic principle is to make the straightening Seamless eccentric reducer elastic-plastic bending, bending by a large degree of curvature becomes smaller, so the pipe in the straightening machine must be repeated bending. The extent of repeated bending steel pipes mainly determined by adjusting the straightening machine.

       Factors affecting the quality of straightening many, such as the curvature of the original tube, pipe size and material straightening model type, adjust parameters.
