Title (EN) ALUMINA FORMING BIMETALLIC TUBE FOR REFINERY PROCESS FURNACES AND METHOD OF MAKING AND USING
(FR) TUBE BIMÉTALLIQUE DE FORMATION D'ALUMINE POUR FOURS À PROCESSUS DE RAFFINERIE ET PROCÉDÉ DE FABRICATION ET UTILISATION
Abstract:
(EN) Provided is a bimetallic tube for transport of hydrocarbon feedstocks in refinery process furnaces, and more particularly in furnace radiant coils, including: i) an outer tube layer being formed from stainless steels including chromium in the range of 15.0 to 26.0 wt.% based on the total weight of the stainless steel; ii) an inner tube layer being formed from an alumina forming bulk alloy including 5.0 to 10.0 wt.% of Al, 20.0 wt.% to 25.0 wt.% Cr, less than 0.4 wt.% Si, and at least 35.0 wt.% Fe with the balance being Ni, wherein the inner tube layer is formed plasma powder welding the alumina forming bulk alloy on the inner surface of the outer tube layer; and iii) an oxide layer formed on the surface of the inner tube layer, wherein the oxide layer is substantially comprised of alumina, chromia, silica, mullite, spinels, or mixtures thereof. Also provided are methods of making and using the bimetallic tube.
(FR) L'invention concerne un tube bimétallique destiné au transport de charges d'alimentation d'hydrocarbures dans des fours à processus de raffinerie, et plus particulièrement dans des bobines rayonnantes de four, comportant : i) une couche extérieure de tube composée d'aciers inoxydables comportant du chrome dans la plage de 15,0 à 26,0 % en poids sur la base du poids total de l'acier inoxydable ; ii) une couche intérieure de tube composée d'un alliage en vrac de formation d'alumine comportant 5,0 à 10,0 % en poids de Al, 20,0 % en poids à 25,0 % en poids de Cr, moins de 0,4 % en poids de Si et au moins 35,0 % en poids de Fe, le complément étant du Ni, la couche intérieure du tube étant formée par soudage par plasma à la poudre de l'alliage en vrac de formation d'alumine sur la surface intérieure de la couche extérieure du tube ; et iii) une couche d'oxyde formée sur la surface de la couche intérieure du tube, la couche d'oxyde étant sensiblement composée d'alumine, d'oxyde de chrome, d'oxyde de silicium, de mullite, de spinelles, ou de leurs mélanges. L'invention concerne également des procédés de fabrication et d'utilisation du tube bimétallique.
