Description
In Stahlheizkörpergliedern befinden sich meist zylindrische Einbaustücke, sogenannte Naben, mit Rechts- und Linksgewinde, in welche Gewindenippel eingreifen, um die einzelnen Heizkörperglieder zusammenzuhalten bzw. mittels Dichtungsringen abzudichten. Ein Drehen der Nabe wird durch eine angegossene Stütze verhindert.In steel radiator elements there are mostly cylindrical chocks, so-called hubs, with right-hand and left-hand threads, in which threaded nipples engage in order to hold the individual radiator elements together or to seal them with sealing rings. A cast support prevents the hub from turning.
Diese zylindrischen Einbaustücke wurden bis jetzt aus Gusseisen oder Temperguss hergestellt und haben ein Gewicht von durchschnittlich 275 g, erhöhen also das Gewicht eines Gliedes um 550 g.Up until now, these cylindrical chocks have been made of cast iron or malleable cast iron and have an average weight of 275 g, increasing the weight of a link by 550 g.
Es wurde nun gefunden, dass man diese Einbaustücke aus verhältnismässig dünnem Stahlblech herstellen kann, das gerollt, gebördelt und verschweisst wird. Daran wird eine Stütze, ebenfalls aus Stahl, angeschweisst, die ein Drehen der Nabe am Glied verhindert. Das Gewicht dieser neuen Einbaustücke ist bei gleicher Fertigkeit um 60% niedriger als das der Guss- oder Tempergussnaben. Ausser dieser Materialersparnis liegen die Vorteile der Stahlnabe in der einfacheren und billigeren Herstellung.It has now been found that these chocks can be produced from relatively thin sheet steel that is rolled, flanged and welded. A support, also made of steel, is welded to it, which prevents the hub from rotating on the link. The weight of these new chocks is 60% lower than that of the cast or malleable cast iron hubs with the same level of skill. In addition to this material saving, the advantages of the steel hub are that it is simpler and cheaper to manufacture.
