A Simulation of the Post-Bending Process of the Pipe

Abstract:Air bending of wide-punch large radius of curvature, as a special bending mode, has been widely applied in the production of large diameter pipeline JCO forming. The JCO forming process is accomplished by several air bending processes. The quality and shape of pipe An finite element analysis of O-forming process in forming Detailed finite element analyses were conducted on O-forming in UOE process for welded pipe,including process loading,blank forming mode and curvature evolvement.And the forming mechanics of O-forming were discussed.The analysis show that O-forming is accomplished by bending of subdividing suspend arc,characterized by evolvement of curvature peaks form one to multiple

Formation of X-120 M Line Pipe through J-C-O-E TechniqueThe line pipe forming operation can be divided into two parts, first is to achieve the required shape in terms of curvature and ovality after formation of the line pipe. The curvature and ovality ultimately effects the final dimensional controls at the later stage i.e. after mechanical expansion of the line pipe. The second part is to make right welding joint geometry to make the final long
