Long radius elbow refers to that  the radius of curvature is 1.5 times of the elbow pipe diameter. Elbow push hot deformation characteristics of tube diameter is determined according to the law of constant volume before and after deformation of the metal material, use smaller diameter than the diameter of the elbow, through mandrel to control the deformation process of the blank, to other parts of the compensation due to thinning of the diameter expands, thereby obtaining a uniform wall thickness of the elbow.
