  ABSTRACT: JCO means that the cross-section of steel pipe forms geometric shapes such as J, C and O in turn. The steel pipe blank directly formed by crimp JCO process has flat area along the edge of the pipe blank seam, which affects the quality of final pipe product. It is necessary to eliminate the flat area along the pipe seam by finishing process. In order to meet requirements of finishing process, it is necessary to optimize the roll surface curvature radius of finishing roll. Aiming at the design requirement of finishing roll for straight seam welded pipe forming, the optimum calculation method and result of roll surface curvature radius of finishing roll were obtained by using the theoretical analysis of metal sheet plastic forming. The result was successfully used in actual production.
