The invention concerns a corrugated strip comprising on its lower edge, seen from the front, at least one pattern (9) projecting downwards whereof the outline is such that, if .alpha.¿m? and .alpha.¿M? represent the extrema of the algebraic value of the angle which the tangent to the outline forms with the horizontal direction, then .alpha.¿m? > .alpha.¿0? and .alpha.¿M? > .alpha.¿0?, in which .alpha.¿0? represents a predetermined angle not less than 5·. The invention is applicable to air distilling columns on board offshore floating terminals or drilling platforms.
Cette bande ondulée comporte sur son bord inférieur, en vue de face, au moins un motif (9) en saillie vers le bas dont le contour est tel que, si .alpha.m et .alpha.M désignent les extrema de la valeur algébrique de l'angle que la tangente au contour forme avec la direction horizontale, on a: .alpha.m > .alpha.0 et .alpha.M > .alpha.0, où .alpha.0 désigne un angle prédéterminé au moins égal à 5~. Application aux colonnes de distillation d'air embarquées sur des plates-formes pétrolières flottantes ou des barges.
