Title
(DE) FÜLLKÖRPER VOM PALLRINGTYP
(EN) RANDOM PALL RING PACKING ELEMENTS
(FR) CORPS DE GARNISSAGE DE TYPE ANNEAU DE PALL
Abstract
(DE) Füllkörper (1) vom Pallringtyp in Form von Hohlzylindern (2) oder Halbzylindern, bei denen Abschnitte (3) der Zylinderwand stegartig in Richtung der Zylinderachse eingebogen sind und die vollständig aus einem temperatur- und chemikalienbeständigen Glas, insbesondere Borosilikatglas 3.3, hergestellt sind. Sie werden vorzugsweise durch Schneiden und Verformen ausgehend von Glasrohren hergestellt.
(EN) The invention relates to random Pall ring packing elements (1) in the form of hollow cylinders (2) or semi-cylinders, in which sections (3) of the cylinder wall are bent inward in a web-like manner in the direction of the cylinder axis and which are produced completely from a temperature- and chemical-resistant glass, in particular borosilicate glass 3.3. The packing elements are preferably produced by cutting and deforming, starting from glass tubes.
(FR) L'invention concerne des corps de garnissage (1) de type anneau de Pall, sous forme de cylindres creux (2) ou de demi-cylindres, dans lesquels des sections (3) de la paroi du cylindre sont incurvées, à la manière de traverses, en direction de l'axe du cylindre, lesdits corps de garnissage étant fabriqués entièrement en un verre résistant à la température et aux produits chimiques, en particulier en verre au borosilicate 3.3. Ils sont fabriqués de préférence par sectionnement et déformation à partir de tubes en verre.
