Embodiment Construction

[0098] see Figure 1 to Figure 3 , shows a first embodiment of a tube 10 according to the invention in the form of a composite film structure and comprising a coextrusion of multiple layers bonded together to provide a one-piece structure. In the arrangement shown, there are three layers including an inner layer 11 , a middle layer 12 and an outer layer 13 .

[0099] The tube 10 is flexible in the sense that, after the tube 10 is constructed, the tube 10 can be presented in a compact state for storage and transportation. For example, the tube can assume a "flat-folded" state in which the tube collapses upon itself. The tube may be rolled into a roll to assume a compact condition, preferably in a "flat folded" condition. Additionally or alternatively, the tube may be sectionally folded back and forth on itself at intervals along its length to assume a compact condition, preferably in a "flat folded" condition.

[0100] In other embodiments, more than one intermediate layer 1...

Abstract

A tube (10) and a method of constructing such a tube, the tube (10) being in the form of a composite film structure comprising a co-extrusion of a plurality of layers bonded together to provide an integrated structure. The layers comprise an inner layer (11), an intermediate layer (12) and outer layer (13). The intermediate layer (12) is of a material compatible with two adjacent layers (11, 13) between which it is interposed, wherein the intermediate layer (12) provides a bridge between the two layers (11, 13) to provide the tube (10) as an integrated structure. The exterior surface (15) of the tube (10) is optionally treated or modified or is provided with a coating, typically for bonding with another substance such as a resinous binder. A hollow structure in the form of a tubular element configured as a pipe and constructed using the tube (10) is also disclosed.

Description

technical field [0001] The present invention relates to a flexible tubular structure which will hereinafter be referred to as a tube. [0002] More particularly, the present invention relates to a flexible pipe of construction for use in hollow structures comprising an inner portion defined by the pipe and an outer portion of reinforced fiber construction integral with the inner portion. The invention also relates to a hollow structure constructed using such a tube. Furthermore, the invention relates to a method of constructing a tube as well as a method of constructing a hollow structure. [0003] The tubes according to the invention are especially, though not exclusively, designed for the construction of elongated hollow structures of composite construction, including tubular structures in the form of ducts, tubular elements such as conduits and tubes, tubular structural elements such as hollow shafts, beams and columns, Hollow bodies such as tanks, hull structures includi...
