Embodiment Construction

[0044]Throughout this description, reference will be made to flexible pipes. It should be understood that a flexible pipe is an assembly of a portion of a pipe body and one or more end fittings in each of which a respective end of the pipe body terminates. figure 1 It is shown how the tubular body 100 is formed from a combination of layered materials forming a pressure-bearing conduit according to an embodiment of the present invention. Although in figure 1 A number of specific layers are shown, but it is to be understood that the invention is broadly applicable to coaxial tubular body structures comprising two or more layers made from a wide variety of possible materials. It is further noted that layer thicknesses are shown for illustrative purposes only. As used herein, the term "composite material" is used broadly to refer to a material formed from two or more different materials, eg, a matrix material and reinforcing fibers.

[0045] like figure 1 As shown, the tubular...

Abstract

An elongate tape element, a flexible pipe body and method of producing a flexible pipe body are disclosed. The tape element (508) has a cross-sectional profile comprising a body portion (510) for being positioned between collapse resistant tape windings (501) such that each body portion (510) lies at least partially in a gap (512) between adjacent collapse resistant tape windings (501); and at least one wing portion (516) extending from an end region of the body portion, the at least one wing portion configured to span the gap and respectively abut with a radially inner surface of an adjacent collapse resistant tape winding.

Description

technical field [0001] The present invention relates to elongate tape elements and methods of forming flexible pipe bodies. In particular, but not exclusively, the invention relates to a tape element for forming a one-layer flexible pipe body. Background technique [0002] Flexible pipe is traditionally used to transport produced fluids, such as oil and / or natural gas, from one location to another. Flexible pipes are particularly useful for connecting subsea locations (which may be deep underwater, eg 1000 meters or more) to sea surface locations. The tube may have an inner diameter typically up to about 0.6 meters (eg diameters may range from 0.05m up to 0.6m). Flexible pipe is generally formed as an assembly of a flexible pipe body and one or more end fittings. The pipe body is generally formed as a combination of layered materials that form a pressure-bearing conduit. The tube structure allows large deflections without creating bending stresses that impair functionali...
