Abstract

Die Erfindung betrifft eine Verfahren zur Herstellung von Rohrbündeln für Heizkessel-Wärmetauscher, ein Rohrbündel für Heizkessel-Wärmetauscher sowie ein Rohr für Heizkessel-Wärmetauscher. Bei dem erfindungsgemäßen Verfahren werden die Rohre (2) mindestens an einem Ende aufgeweitet, danach gebündelt, und jedes Rohr (2) des Rohrbündels (1) mit dem Nachbarrohr verschweißt. Die Aufweitung der Rohre (2) erfolgt durch rundes Aufbördeln des Rohrrandes, so daß ein umlaufender, flanschartiger Kragen (3) entsteht, der im wesentlichen in einer Ebene angeordnet ist, die rechtwinklig zur Längsachse (4) des Rohres (2) verläuft. Vorzugsweise werden die Kragen (3) nach dem Aufweiten zu Vielecken geschnitten und an den Kanten (8) verschweißt.

The invention relates to a method for producing tube bundles for boiler heat exchangers, a tube bundle for boiler heat exchangers and a tube for boiler heat exchangers. In the method according to the invention, the tubes (2) are expanded at least at one end, then bundled, and each tube (2) of the tube bundle (1) is welded to the neighboring tube. The tubes (2) are widened by round flaring of the tube edge, so that a circumferential, flange-like collar (3) is formed, which is essentially arranged in a plane that is perpendicular to the longitudinal axis (4) of the tube (2). After the expansion, the collars (3) are preferably cut into polygons and welded at the edges (8).
