Problems solved by technology

Consequently, this construction process does not favor the manufacture of long tubes that form the transport network for liquids and gases; that is, those tubes that are much longer than available mandrels and that constitute the length of a continuously extending pipeline between two remote stations those tubes, the two sites may be separated by hundreds to thousands of kilometers

Embodiment Construction

[0122] see Figure 1-22 A first embodiment of the present invention relates to an elongated hollow structure constructed in the form of a tubular element such as pipe 10, and a method of constructing the pipe on a continuous basis.

[0123] The tube 10 is of composite construction, comprising a radially inner portion 11 and a radially outer portion 13, the two parts 11 and 13 merging together to provide a complete tube wall structure. In said structure, the exterior 13 is enclosed in a protective sheath 14 comprising a hardenable component 16 such as glue or concrete comprised of an outermost layer 18 which may be of any suitable material, Such as geotextiles. The protective sheath 14 serves to provide protection to the pipe 10 against compressive loads to which the pipe may be subjected once installed.

[0124] The interior 11 comprises an inner liner 15 to which a layer 17 of resin absorbent material is bonded to one face. The other face of the inner sleeve 15 defines an ...

Abstract

An elongate hollow structure such as a pipe (10) and a method of constructing such an elongate hollow structure. The pipe (10) comprises a radially inner portion (11) and a radially outer portion (13), with the two portions (11, 13) merging together to provide an integrated tubular wall structure. The method comprising: providing the radially inner portion (11) in the form of an inner tube (21) and assembling the radially outer portion (13) about the inner tube (21). The outer portion (13) comprises an outer tube (30) of fibre reinforced composite construction surrounded by a flexible outer casing (31). The inner tube (21) is expanded to give form and shape to the outer portion (13).

Description

technical field [0001] The present invention relates to an elongated hollow structure of composite construction, including in particular a tubular structure. [0002] Although the invention is specifically designed to relate to the construction of tubular structures in the form of tubes, it can also be applied to the construction of other elongated hollow elements including: tubular elements such as conduits and pipes; tubular structural elements such as shafts , beams, and columns; and other tubular elements of composite construction. Background technique [0003] The following description about the background art is only for the convenience of understanding of the present invention. This description does not constitute or admit that any of the material referenced is or was common general knowledge as at the priority date of the application. [0004] It is known to use fiber-reinforced plastic composite materials for the construction of pipes. Typically, such pipes are c...
