Title
(EN) PIPE DEFORMING METHOD AND APPARATUS
(FR) APPAREIL ET PROCEDE DE DEFORMATION DE TUBE
Abstract
(EN)
Pipe deforming apparatus in which a pipe (12) is pushed through a heating station (13) by a hydraulically actuated pushing ram (15) and is caused downstream of the heating station (13) to curve at the heating station (13) by means of a clamp head (24) clamped to the pipe (12) and mounted on a pivot arm (25). Curving may take place through 180o clockwise or anticlockwise. A reduction in pipe wall thinning at the outside of the curve is obtained by means of a lobed induction coil (67) in which water cooled means (68) are provided between the pipe (12) and the coil (67) on the side of the pipe (12) which will define the outside of the curve. The apparatus may be modified to provide for pipe coiling and for localised thickening of pipe walls.
(FR)
Dans l'appareil de déformation de tube de la présente invention, un tube (12) est poussé au travers d'une station de chauffage (13) par un bélier poussoir actionné hydrauliquement, et il est courbé en aval de la station de chauffage (13) à l'aide d'un collier de serrage (24) serrant le tube (12) et monté sur un bras de pivot (25). La courbure peut s'effectuer sur 180o dans le sens des aiguilles d'une montre ou dans le sens contraire à celui des aiguilles d'une montre. Une réduction de la paroi du tube s'amincissant à l'extérieur de la courbure est obtenue à l'aide d'une bobine d'induction lobée (67) dans laquelle des moyens refroidis par eau (68) sont prévus entre le tube (12) et la bobine (67) du côté du tube (12) qui définira l'extérieur de la courbure. L'appareil peut être modifié pour assurer le refroidissement des tubes et pour effectuer un épaississement localisé des parois des tubes.
