PROBLEM TO BE SOLVED: To provide a device for detaching an anticorrosive core, capable of easily removing the anticorrosive core from a perforated part under uninterrupted flow conditions.SOLUTION: A device for detaching an anticorrosive core comprises: a rod-like member 8 reciprocable to be able to reach from a branching part 3c side of a housing 3 surrounding a fluid pipe 2 in a sealed shape to a position of the anticorrosive core 5 attached to a perforated part 2a of the fluid pipe 2; and a claw part 14 positioned in the vicinity of a tip end 9 of the rod-like member 8, passing a hole part 5A of the anticorrosive core 5 in the forward movement from the branching part 3c side, and engaged with the anticorrosive core 5 in the backward movement to the branching part 3c side. The claw part 14 is provided in the vicinity of the tip end 9 of the rod-like member 8. Also, at least a portion of the claw part 14 is operable in the direction of the rod-like member 8 by the operation of an adjusting device 6b provided in a proper position of the rod-like member 8, and the anticorrosive core 5 being engaged with the claw part 14 is deformed in an internal diameter direction with the operation of the claw part 14. |
