| 主权项 | 1. A method for cutting a pipe (2) made from thermoplastic material, characterised in that it comprises, in combination, the following steps: localised and circumferentially heating of a localised axial portion (3) of the pipe (2) at a predetermined operating temperature; cutting without removal of chippings, using a cutting tool (4), of the heated axial portion (3), for obtaining pieces of the pipe; wherein the heating step comprises a step of emitting circumferentially electromagnetic waves in the direction of the axial portion (3) of the pipe (2). | ||
