Abstract (en)

[origin: EP2295161A1] As illustrated in Fig. 3 , a mating surface of a lower clamping member (1b) is provided with protrusions (11) and a mating surface of an upper clamping member (1a) is provided with recesses (12) that accommodate the respective protrusions (11), wherein the protrusions (11) have surfaces (13a) perpendicular to an axis of a pipe material (4) and, wherein the surfaces (13a) are provided to be flush with a surface (13b) of the lower liner (3b) in the lower clamping member (1b) that abuts against a step forming surface (2c) so that the step forming surface (2c) of the upper liner (3a) and the step forming surface (2c) of the lower liner (3b) abut against the same surface due to a pressing force of a flare forming process when clamping the pipe, so that formation of a bump in a pipe axial direction of the upper and lower liners (3a, 3b) can be prevented.
