Title
(EN) METHOD FOR THE PROTECTION OF A COILED TUBE HEAT EXCHANGER
(FR) PROCEDE DE PROTECTION D'UN ECHANGEUR DE CHALEUR A TUBES ENROULES EN SPIRALES
Abstract
(EN)
Method of manufacturing a tubular heat exchanger comprising an outer tube (2) and at least one inner tube (1, 4) placed inside the outer tube and if necessary provided with outer spacers. The tubes have the form of a spiral. The inner diameter of the outer tube (2) is larger than the outer diameter of the inner tube (1) or larger than the sum of the outer diameter of the inner tubes (1 and 4). The outer tube (2) is separately formed to a spiral and at least one inner tube (1, 4) is formed to a spiral with the same pitch as the spiral formed by the outer tube. The outer diameter of the spiral of the inner tube falls inside the inner circumference of the outer tube. Then, the spiral formed by the inner tube (1, 4) is screwed into the spiral formed by the outer tube (2) and subsequently attachement- and sealing-arrangements (3), known per se, are fixed to the ends of the outer spiral-tube (2) and to the ends of at least one inner spiral-tube (1).
(FR)
Le procédé décrit sert à fabriquer un échangeur de chaleur tubulaire comprenant un tube externe (2) et au moins un tube interne (1, 4) disposé à l'intérieur du tube externe et pourvu, si nécessaire, d'éléments d'espacement extérieurs. Les tubes ont la forme d'une spirale. Le diamètre intérieur du tube externe (2) est supérieur au diamètre extérieur du tube interne (1) ou à la somme des diamètres extérieurs des tubes internes (1 et 4). Le tube externe (2) forme séparément une spirale et au moins l'un des tubes internes (1, 4) forme une spirale ayant la même hauteur que la spirale formée par le tube externe. Le diamètre extérieur de la spirale du tube interne est compris à l'intérieur de la circonférence intérieure du tube externe. La spirale formée par le tube interne (1, 4) est ensuite vissée dans la spirale formée par le tube externe (2), puis un type connu en soi d'agencements de fixation et d'étanchéité (3) sont fixés aux extrémités du tube spiralé externe (2) et aux extrémités d'au moins un tube spiralé interne (1).
