Abstract

A flaring device for pipe ends including an insert member centrally insertable into a pipe end, the insert member having mounted thereon synchronously operable pressure plungers arranged at the outer circumference thereof and bringable into engagement with the inner circumference of the pipe end to be flared, includes a calibrating ring for determining a maximum outer circumference defined by the pressure plungers mounted on the insert member, the calibrating ring being in operative engagement with the insert member.
