Japanese Patent JP2014168793

A

PROBLEM TO BE SOLVED: To provide a chamfer correction apparatus for a cut end part of a pipe, capable of correcting only a usable pipe in a proper shape by chamfering the end part of the pipe, by discriminating the possibility of use of the obliquely cut pipe.SOLUTION: The chamfer correction apparatus 1 for the cut end part of the pipe comprises a holding part 2, a substantially columnar insertion part 4 extended from the holding part 2 and an inside chamfer part 11 for chamfering the inner peripheral edge of the cut end of the pipe, and the inside chamfer part 11 is provided in a part separated from the holding part 2 on an outer peripheral surface of the insertion part 4, so that when the cut end of the pipe is inclined to the axis of the pipe, a tip-entering margin part 15 of the cut end is provided between the inside chamfer part 11 and the holding part 2, and the margin part 15 is provided with an abutting part 16 set so that the tip of the cut end abuts when the pipe length up to the tip from the innermost end of the inclined cut end exceeds the predetermined length, for discriminating the possibility of use of the obliquely cut pipe.
