An elongated conduit including a tubular outer pipe, an elastic inner pipe and an annulus between the outer pipe and inner pipe, the conduit being provided with a fluid supply device, the outer pipe being provided with an inlet for introducing the fluid in the annulus between the outer pipe and the inner pipe, which inlet communicates with the fluid supply device.

Double layer conduit

The present invention relates to use of a composite material as a fluid barrier under cryogenic conditions, the composite material having: (a) a tensile Young's modulus of less than 50 GPa; and (b) a tensile strain at break of at least 5% at ambient conditions. The present invention further relates to a sandwich and a containment system for a cryogenic fluid comprising the composite material.

Use of a composite material as a barrier under cryogenic conditions

A method of joining a pair of tubular ends () comprises: providing the tubular ends with intermeshing tapered edges (); joining the tubular ends by inserting an adhesive between the tapered edges and pressing the tapered edges () together; arranging an axial load carrier collar () around the joined tubular ends; inserting an adhesive between the inner surface of the collar () and the outer surfaces of the joined tubular ends (); and inducing the adhesive to bond the inner surface of the collar () to the outer surfaces of the joined tubular ends. The axial load carrier collar () may be equipped with a series of flexible reinforcement strips (), which carry a majority of axial loads exerted on the tubular joint, such that only a minimal axial load is exerted on the bonded tapered edges ().
