Problems solved by technology

[0016] When flexible pipes are connected to equipment they may develop lap loads which may result in reduced service life of the flexible pipe and / or in some cases increased damage to the connection or the equipment the flexible pipe is connected to risks of
The added bend limiter, which is only required when installing flexible pipe, may increase this lap load

Embodiment Construction

[0039] Throughout this specification, reference will be made to flexible pipe. It will be appreciated that flexible pipe is an assembly of a portion of a pipe body and one or more end fittings, a respective end of the pipe body terminates to each end fitting of said end fittings. loading. figure 1 It is shown how a pipe body 100 according to an embodiment of the invention is formed from a combination of layered materials forming a pressure-bearing conduit. Although in figure 1 An unbonded tube formed from a number of specific layers is shown in , but it should be understood that the invention is broadly applicable to other unbonded or bonded tube structures made of a wide variety of possible materials. For example, the present invention can be broadly applied to constructions of unbonded pipes as described in Table 1 of API Recommendation 17B, 5th Edition.

[0040] For example, the pipe body may be formed from layers of polymer, metal, composite or a combination of differen...

Abstract

An element (1) for a bend limiter, the element (1) comprising a first part (2) and a second part (3), the first part and the second part being provided together for receiving a flexible tube In use, the two parts (2, 3) are pivotally connected together at a first part (4; 6) of the two parts and at a second part (5; 7) of the two parts ) can be connected together or releasably connected together. Successive elements can be fastened together to form a bend restrictor.

Description

technical field [0001] The present invention relates to bend restrictors, in particular to elements for bend restrictors and bend restrictors made from the elements. Background technique [0002] Traditionally, coiled pipes are used to transport fluid products, such as oil and / or gas and / or water, from one location to another. Coiled tubing is particularly useful in connecting a subsea location (possibly at depth) to a sea surface location. The inner diameter of the tubing can typically be up to about 0.6 meters (eg, diameters may range from 0.05m 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 laminated materials that form a pressure-containing pipe. The pipe structure allows large deflections throughout the life of the pipe without incurring bending stresses that impair the pipe's functionality. The pipe body is generally constructed as a composite str...
