Abstract
A tube cutting device includes a tube holding member that holds a target tube from an inside of the target tube, allowing the target tube to be cut from an outside; and a cutter carrier member that includes a cutter eccentrically pivotable relative to the geometry axis of an elongate body of the cutter carrier member, such that when in a non-extended position, the cutter is positioned within a diameter of the elongate body, and when in an extended position, the cutter extends outwardly and cuts into a wall of the target tube.
Claims17
A tube cutting device, comprising:
- a tube holding member that holds a target tube from an inside of the target tube, allowing the target tube to be cut from an outside;
- and
- a cutter carrier member that includes an elongate body and a cutter eccentrically pivotable relative to a geometry axis of the elongate body, such that when in a non-extended position, the cutter is positioned within a diameter of the elongate body, and when in an extended position, the cutter extends outwardly and cuts into a wall of the target tube.
A method for cutting a tube, comprising:
- extending a tube holding member through a first tube hole defined in a tubesheet;
- advancing the tube holding member into a target tube;
- holding on an inner surface of the target tube by the tube holding member;
- extending a cutter carrier member through a second tube hole defined in the tubesheet;
- extending the cutter such that the cutter extends outwardly from an elongate body of the cutter carrier member;
- and
- cutting the target tube,
- wherein each of the tube holding member and the cutter carrier member has a diameter which allows each of the tube holding member and the cutter carrier member to extend through tube holes of the tubesheet.
