This method is also called the circumference deformation method, and its forming process is a full width along the tube billet bending deformation, bending radius R frame by frame.When center deformation Angle theta is less than 180 DHS, tube billet and roll up and down along the entire width of the contact.When the center deformation Angle theta is more than 180 DHS and less than 270 DHS, under the tube billet and roller contact, only roll on contact with the middle part of tube billet.When theta is greater than 270 DHS tube billet in closed groove on with guide ring roll forming.
The advantages of this method of forming is a uniform deformation, roll processing is simple and has a certain commonality.Weakness is lack of sufficient tube billet edge deformation, easy cause edges while production of thin-walled tube bulge.Thick wall pipe weld present pointed peach shape, forming is not stable, easy to form a reverse, wandering, edge slightly greater than the edge bending method.The adoption of the vertical roll forming process guidance, overcomes the drawback of poor stability.Therefore, the deformation method is widely used in outer diameter less than 114 mm and wall thickness of 2.5 ~ 5.5 mm small diameter welded pipe production, particularly suitable for intermittent production of short welded pipe units.
