Abstract

The disclosure relates to a method for manufacturing a pipe made of thermoformable foam, comprising the following steps: a) inserting at least one sheet of thermoformable foam into a shaping mould provided with lips that are configured to engage with one another, the shaping mould being pre-installed in or on a tool that is capable of closing and opening the lips, the at least one sheet having two side edges that connect a first end edge to a second end edge; b) closing the lips of the shaping mould by means of the tool so as to pre-form the at least one sheet into the shape of a pipe in which the side edges thereof are joined together; and c) heating the at least one sheet, with its shaping mould, to a temperature suitable for welding the side edges and for thermoforming the pipe.
