Abstract

The flat metal flange is for welding or soldering to a pipe and in its upper surface in the area of welding to the pipe a groove is produced. The narrow ring left after the groove has been made stretches through the application of welding or soldering heat and the flange seal surface remains straight. USE/ADVANTAGE - To weld a flange to a pipe without distortion.

Description

Die Erfindung betrifft eine neben dem Anschweißbereich in die Oberfläche eingearbeitete Nut.The invention relates to an in addition to the welding area in groove worked into the surface.

Durch Flansche, die an Rohr und Rohrformstücke geschweißt werden, können Einzelelemente zu Rohrleitungen zusammengeschraubt werden. Ferner werden Flansche im Apparatebau eingesetzt, um diese zu trennen oder warten zu können. Um Flanschverbindungen sicher abdichten zu können, müssen die Flanschdichtflächen plan sein.Through flanges that are welded to pipe and pipe fittings individual elements can become pipelines be screwed together. Flanges are also in the Apparatus construction used to separate them or to wait can. In order to be able to securely seal flange connections, the flange sealing surfaces must be flat.

Der Erfindung liegt die Aufgabe zugrunde, einen Flachflansch verzugsfrei anschweißen zu können.The invention has for its object a To be able to weld the flat flange without distortion.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst , daß der durch das Einbringen einer Nut 1) in die Flanschoberfläche der verbleibende Ring 2) im Anschweißbereich sich durch die Wärmeeinwirkung des Schweißens bzw. Lötens verzieht, die Dichtfläche jedoch eben, d. h. plan bleibt.This object is achieved in that the introduction of a groove 1 ) into the flange surface of the remaining ring 2 ) in the welding area is distorted by the heat of welding or soldering, but the sealing surface remains flat, ie flat.

Die mit der Erfindung erzielten Vorteile bestehen inbesondere darin, daß Flachflansche z. B. nach DIN 2576 eingesetzt werden können, ohne anschließend bearbeitet werden zu müssen und das auf den Einsatz von Vorschweißflanschen z. B. nach DIN 2633, die einen erheblich höheren Materialeinsatz bedeuten, verzichtet werden kann.The advantages achieved with the invention exist especially in that flat flanges z. B. according to DIN 2576  can be used without being subsequently edited to have to be and that on the use of Welding neck flanges z. B. according to DIN 2633, which is considerable higher use of materials mean can be dispensed with.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in folgendem näher beschrieben.An embodiment of the invention is in the drawing shown and is described in more detail below.

Eine neuartige Konstruktion, um flache Metallflansche verzugsfrei an Rohr anzuschweißen oder anzulöten.A new type of construction to prevent flat metal flanges from warping to be welded or soldered to a pipe. Dieses ist dadurch gekennzeichnet, daß in die Oberfläche des Flansches, im Anschweißbereich des Rohres eine Nut eingebracht ist.This is characterized in that a groove is made in the surface of the flange in the welding area of the tube. Der durch das Einbringen der Nut verbleibende schmale Ring verzieht sich durch das Einbringen der Schweiß- bzw. Lötwärme und die Flanschdichtfläche bleibt gerade.The narrow ring left by inserting the groove warps through the introduction of welding or soldering heat and the flange sealing surface remains straight.
