    • The present invention suggests that a grid-shaped spreader be used for guiding and holding the branch pipes of a tube nest, especially in steam generators. The grid bar (1, 2) ends are fitted in slots provided on a single-piece central ring (3) which is surrounded on three sides by a C-shaped outer ring - seen in cross-section - with salient cross members (10), one in the upper part and one in the lower part. Each cross member is turned to the central ring (3) and engages in a groove (9) located opposite it in a front portion of said central ring (3) and in the notches provided in the grid bars (1, 2). The inventive spreader is intended to be placed mainly in steam generators as used in pressurized water reactor plants.
