Abstract
A tube spacing grid for the guidance of tubes such as in steam generators includes mutually intersecting grid rods disposed in two planes and surrounded as a frame by an outer ring. The outer ring has a circling groove on its interior face and the grid rods are inserted in seating slots formed in an interior face of a one-piece inner ring (B). A tongue and groove connection is provided between the grid rods and the inner ring. The inner ring, with the grid rods inserted in the slots and retained at a radial and axial distance from each other, is encircled by a multiple-part, particularly a two-part in axial direction, outer ring.
