WIPO Patent Application WO/2011/007951
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for manufacturing a tube coil to be used in small- and mid-sized nuclear steam generators. The apparatus for manufacturing a tube coil to be used in small- and mid-sized nuclear steam generators comprises a rotatable drum configured with a spiral frame formed on an outer surface thereof about a central axis constituted by a rotating shaft driven to rotate by a driving apparatus, wherein a straight tube is fixed to a fixing member formed on an end of the spiral frame formed on the outer surface of the drum so as to be conveyed together with a conveying apparatus along a lengthwise direction of the drum during the rotation of the drum, and to be wound as a coil along the spiral frame formed on the outer surface of the drum, in order to maintain a uniform gap or pitch between one tube coil and another tube coil during manufacturing.
