Abstract
The invention is related to a tube extracting device for compressing a tube end extended from a conventional drum of a boiler to remove the tube. The device includes a housing comprised of an outer clamping plate and an inner clamping plate pivotally connected by a pin. A grip for receiving the tube extends down from the housing. A hydraulically-powered ram moves the outer clamping plate relative to the inner clamping plate so that the grip closes around and compresses the tube. The power to the hydraulic ram is then shut, springs return the outer clamping plate and the inner clamping plate to their original position, which, in turn opens the grip so that the removed tube can be released from the device. The device is then lifted by a handle and the tube is removed from the drum.
