Abstract
(EN)
In this aluminum extruded flat perforated pipe, the anticorrosion property, at internal surfaces of a plurality of pores independently and parallelly extending in the pipe axis direction, is effectively enhanced. In an aluminum extruded flat perforated pipe 10 formed through an extrusion process by using an aluminum pipe body material and an aluminum sacrificial anode material which is electrochemically less noble than the aluminum pipe body material, a sacrificial anode part 18 is formed by causing the aluminum sacrificial anode material to be exposed at least in one portion of a hole-internal circumference section of each of the plurality of pores 12 extending in the pipe axis direction.

L'invention concerne un tuyau perforé plat extrudé en aluminium, dont la propriété anticorrosion, au niveau de surfaces internes d'une pluralité de pores s'étendant indépendamment et parallèlement dans la direction d'axe du tuyau, est efficacement améliorée. Dans un tuyau perforé plat extrudé en aluminium (10) formé par le biais d'un procédé d'extrusion en utilisant un matériau de corps de tuyau en aluminium et un matériau d'anode sacrificielle en aluminium qui est moins noble sur le plan électrochimique que le matériau de corps de tuyau en aluminium, une partie d'anode sacrificielle (18) est formée en faisant en sorte que le matériau d'anode sacrificielle en aluminium soit exposé au moins dans une partie d'une section de circonférence interne au trou de chacun de la pluralité de pores (12) s'étendant dans la direction d'axe du tuyau.
