Abstract

A tube cutting device for cutting a tube of a waste steam generator including: a body configured to transmit power; a tube-shaped rotary body provided on a side surface of the body and having a horizontal rotary shaft configured to rotate with the power supplied from the body; a plurality of clamps provided along an outer peripheral surface of a first end portion of the rotary body and configured to fix the rotary body to the tube to be cut; a saw provided on a second end portion opposite to the first side end portion of the rotary body and configured to rotate together with the rotary body to cut the tube; and a fitting member configured to be inserted into a hollow portion formed on a center portion of the saw.

Description

technical field [0001] The present invention relates to a pipe cutting device for cutting pipes of an exhaust steam generator, and more specifically relates to a pipe cutting device. For a nuclear power plant, the pipe cutting device includes a saw. The saw is installed inside the small pipe for cutting the small pipe attached to the steam generator when removing the steam generator inside the nuclear power plant. Background technique [0002] In general, a nuclear power plant is divided into a nuclear steam supply system (Nuclear Steam Supply System) centered on a nuclear reactor, a generator system such as a turbine (turbine) that receives steam supply and turns a generator, and other incidental equipment. [0003] Here, the nuclear steam supply system includes: a pressurizer; a steam generator; a main coolant pump; a nuclear reactor in which nuclear fuel is split, and the like. [0004] Among them, the steam generator is a device that plays the role of causing high-tempe...
