METHOD FOR PRODUCING MEMBRANE WALL, PIPE BENDING DEVICE FOR MANUFACTURING TRANSFER DUCT AND METHOD FOR MANUFACTURING TRANSFER DUCT USING SAME

摘要

Disclosed is a method for producing a cylindrical membrane wall comprising multiple tubes, in which a coolant flows. The method comprises the steps of: producing a plurality of sub-bundles by welding a plurality of tubes to each other after disposing the plurality of tubes along the longitudinal direction to be neighbored side by side; producing a plurality of panel-type bundles by welding the plurality of sub-bundles to each other; producing a plurality of curved bundles having a curved surface of a given curvature by pressing the plurality of panel-type bundles; and welding the curved bundles to each other using a jig.
