Embodiment Construction

[0034] Reference is made to the hose throughout the instructions. It should be understood that a hose is an assembly of a portion of a tubular body and one or more end fittings, the ends of the tubular body terminating in each end fitting. figure 1 Illustrated how the pipe body 100 is formed from a composite of materials forming a pressure conduit-containing laminate in accordance with an embodiment of the present invention. Although in figure 1 A number of individual layers are shown, but it should be understood that the invention is broadly applicable to composite pipe structures comprising two or more layers. It should also be noted that the various layer thicknesses are shown for illustrative purposes only.

[0035] Such as figure 1 As shown, the tubular body includes an innermost carcass layer 110 and a pressure sheath 120 . Carcass 110 provides an interlocking metallic structure that can be used as the innermost layer to prevent internal pressure sheath 120 from full...

Abstract

An elongate tape element and method of manufacturing flexible pipe body are disclosed. The elongate tape element (12) which is for providing at least one helically wound layer of windings in a flexible pipe body (10), comprises an elongate body having a base surface (20), a top surface (22) opposed to the base surface and opposed first and second side walls (24, 26) extending between the base and tope surface wherein at least one surface and/or side wall of the body comprises a recessed region for receiving a respective portion of a tape element holder member when said tape element is wound to form a layer of windings.

Description

technical field [0001] The present invention relates to hoses that can be used to transport fluids, such as production fluids. In particular, but not exclusively, the invention relates to a hose body and a method for manufacturing a hose body having layers formed by adjacent windings of interlocking helically wound ribbon. The invention also relates to tapes for forming such layers. Background technique [0002] Traditionally, hoses have been used to transport production fluids such as oil and / or gas and / or water from one location to another. Hoses are especially useful in connecting one location on the seafloor to another or at sea level. Hoses are generally formed as an assembly of a length of hose body and one or more end fittings. The pipe body is usually formed as a composite of several tubular layers of material forming the fluid and pressure containing conduit. The tubing structure allows for large deflections without creating bending stresses that impair the func...
