Description

The invention relates to a method for manufacturing a non-dismountable sealed convection between two conduits made of non mutually weldable metals. The method is characterized in that its consists in assembling two plates, each of which being of a metal weldable to one of the two conduits, in centrally boring in these plates a circular hole of the same diameter with the conduit inner cross-section, and in that each conduit is welded to its respective plate, coaxially with the respective hole. This can be applied to conduits for the circulation of radioactive substances in the nuclear field

Abstract (French)

L'invention concerne un procede de realisation d'une jonction etanche et non demontable entre deux conduites en metaux distincts et non soudables entre eux. Le procede est caracterise en ce que l'on assemble par placage deux plaques, chaque plaque etant realisee dans un metal soudable a l'une des conduites, en ce que l'on perce au centre des plaques un trou circulaire de meme diametre que celui de la section interne de la conduite et en ce que l'on soude chaque conduite, coaxialement au trou, a la plaque correspondante. Ceci est applicable aux conduites transportant des produits actifs dans l'industrie nucleaire
