Title (EN) CONDUITS WITH CAPILLARY STRUCTURES
(FR) CONDUITS DOTÉS DE STRUCTURES CAPILLAIRES
Abstract:
(EN) The present disclosure provides a conduit (10). The conduit (10) includes (i) an annular wall (66) composed of a polymeric material, the annular wall (66) defining an annular passageway; (ii) a plurality of channels (68) extending along a length of an inner surface (62) of the annular wall (66); and (iii) a slip material located in the channels (68), the slip material forming a capillary structure (70) in the channels (68), and the capillary structures (70) protruding radially inward from the annular wall (66).
(FR) La présente invention concerne un conduit (10). Ce conduit (10) comprend (i) une paroi annulaire (66) composée d'un matériau polymère, la paroi annulaire (66) définissant un passage annulaire ; (ii) une pluralité de canaux (68) s'étendant le long d'une longueur d'une surface interne (62) de la paroi annulaire (66) ; et (iii) un matériau de glissement situé dans les canaux (68), le matériau de glissement formant une structure capillaire (70) dans les canaux (68), et les structures capillaires (70) faisant saillie radialement vers l'intérieur à partir de la paroi annulaire (66).
