Document Type and Number:
WIPO Patent Application WO/2012/063661
Kind Code:
A1
Abstract:
A method for producing a steam generator in which vibration-preventing members (14) are positioned between heating tubes (5) comprises: a step for a positioning spacing jigs (25) between adjoining vibration-preventing members (14) so as to insert the vibration-preventing members (14) between the heating tubes (5), thereby retaining the spacing of the vibration-preventing members (14); a step for welding a holding member (16) to the vibration-preventing members (14) such that the vibration-preventing members (14), the spacing of which is retained by the spacing jigs (25), are linked to each other; and a step for removing the spacing jigs (25) after the holding member (16) has been welded to the vibration-preventing members (14).
