    • A durable, semi-rigid, single-layered flexible duct having a sleeve made of a single aluminum layer and a resilient wound element disposed at the mid-point of the overlap region of the aluminum layer. The wound element imparts corrugations to the sleeve, such that the duct is extendible between a compacted configuration suitable for storage and for shipping and an extended configuration suitable for installation in a gas transport arrangement. Closely and evenly-spaced ridges that are situated in between the corrugations, add rigidity and durability to the duct. The inward-facing surface of the aluminum ribbon is substantially smooth and featureless except for the helical corrugations imparted by wire winding and the closely and evenly-spaced ridges. The aluminum sleeve is of a predetermined thickness rendering the duct substantially rigid when in an extended configuration and enabling the duct to maintain its substantial rigidity upon extension from a compacted configuration.
    • 一种耐用的半刚性的单层柔性导管,其具有由单个铝层制成的套筒和设置在铝层的重叠区域的中点处的弹性缠绕元件。 伤口元件向套筒施加波纹,使得管道可在适于存储和运输的压实构造和适于安装在气体输送装置中的延伸构造之间延伸。 位于波纹之间的紧密均匀的脊,为管道增加了刚性和耐久性。 铝带的面向内的表面基本上平滑且无特征,除了由线缠绕和紧密且均匀间隔的脊部产生的螺旋波纹。 铝套筒具有预定的厚度,使得当处于延伸构型时,管道基本上是刚性的,并且使得管道能够在从紧凑构型延伸时保持其实质的刚性。

    • A semi-rigid, flexible duct including a pair of coaxial sleeves, namely an inner sleeve and an outer sleeve disposed parallel to and about the inner sleeve and a resilient wound element disposed between the sleeves. Each of the inner sleeve and the outer sleeve constitutes an aluminum foil ribbon. The wound element imparts corrugations to the two sleeves, such that the duct is extendible between a compacted configuration suitable for storage and for shipping and an extended configuration suitable for installation in a gas transport arrangement. Both the inner sleeve and the outer sleeve are of a predetermined thickness rendering the duct substantially rigid when in an extended configuration and enabling the duct to maintain its substantial rigidity upon extension from a compacted configuration. Optionally, at least one of the sleeves further includes a second, plastic layer bonded to the aluminum foil ribbon layer.
    • 一个半刚性柔性管道,包括一对同轴套管,即内套筒和外套筒,平行于和围绕内套管布置,弹性缠绕元件设置在套筒之间。 内套筒和外套筒均构成铝箔带。 伤口元件向两个套管施加波纹,使得管道可在适于存储和运输的压实构造和适于安装在气体输送装置中的延伸构造之间延伸。 内套筒和外套筒均具有预定的厚度,使得当处于延伸构型时,管道基本上是刚性的,并且使得管道在从紧凑构型延伸时能够保持其基本的刚度。 可选地,至少一个套筒还包括结合到铝箔带层的第二塑料层。
