<p>A multiple tool device (1), for preparing tubular elements (1000) to be welded by electrofusion, has a cup member (2) to be associated with the end portion (1001) of a tubular element (1000) and provided with motion transmission means (11) adapted to turn the multiple tool device (1). The device includes a scraper means (20) adapted to remove the outer surface layer of the end portion (1001) and a facing means (40) which has a working motion that is opposite with respect to the scraper means (20) and that is adapted to face the edge of the end portion (1001) so as to make it perpendicular to the axis (1010) of the tubular element (1000).</p> |
