Abstract: A device for expanding and shaping the end of pipes includes a head with means for connecting to an elastically deformable expanding element with a first elongated portion for being introduced into the end of the pipe, the expanding element having a central through hole, and an extracting member including an expansion head suitable to move from outside to inside the central through hole of the expanding element or the other way round, so as to cause deformation, or to allow the expanding element to elastically return to an undeformed state, means for moving said extracting member, wherein: —the connecting means is suitable for steadily constraining the expanding element to the head for a plurality of different pipes and to allow the expanding element to be replaced when worn out, the elongated portion of the expanding element is made of an elastically deformable polyurethane plastic material having certain characteristics.

Abstract: A device for expanding and shaping the end 1A of pipes 1, comprising: a head 10C comprising means 11 for connecting the head 10c itself to an expanding element 2 expanding said end 1A of the pipe 1, said expanding element being made of an elastically deformable material, wherein said expanding element 2 comprises a first elongated portion 2D having an outer surface 2A with a maximum diameter D1 which is less than or equal to the internal diameter D2 of the end 1A of the pipe to be expanded and shaped, so that at least said first elongated portion 2D of the expanding element can be introduced into said end 1A of the pipe 1, wherein said expanding element 2 comprises a central through hole 2B arranged coaxially to a longitudinal axis LI? of said expanding element 2 delimited by an inner surface 2C, an extracting member 3 comprising an expansion head 3A suitable to move, coaxially to the longitudinal axis L1? of said expanding element 2, from the outside to the inside of said central through hole 2B of the expan
