Problems solved by technology

Howling can cause catastrophic failure of certain portions of flexible piping and auxiliary equipment connected to such flexible piping, and can prove expensive to correct
Alternatively, according to conventional solutions, the fluid velocity of the transported fluid must be reduced to avoid whistling, which may lead to a degradation of the allowable supply volume

Embodiment Construction

[0087] Throughout this specification, reference will be made to flexible conduits. It should be understood that certain embodiments of the present invention are suitable for use with a wide variety of flexible conduits. For example, certain embodiments of the invention can be used with respect to flexible pipe and associated end fittings of the type manufactured in accordance with API 17J. Such flexible pipes are often referred to as unbonded flexible pipes. Likewise, certain other embodiments of the present invention may be used with flexible pipe and associated end fittings for flexible pipe of composite type construction. This composite type of flexible pipe and its manufacture is currently standardized by API. Such a flexible conduit can comprise adjacent tubular layers bonded together.

[0088] go to figure 1 , it will be appreciated that the flexible pipe shown is an assembly of a portion of the pipe body and one or more end fittings, with respective ends of the pipe...

Abstract

Apparatus, flexible pipe bodies and methods are disclosed. The apparatus comprises at least one connector body comprising a first restraint arm portion and opposing further restraint arm portions each extending outwardly away from a common intersection area of ​​said connector body and comprising a respective locking surface and at least a support arm portion, said at least one support arm portion extending substantially perpendicular to the opposing arm portion from said common intersection area and terminating in a flared end portion providing an abutment surface, wherein between said common intersection area and the abutment surface The distance between them is less than 60% of the predetermined thickness.

Description

technical field [0001] The present invention relates to apparatus and methods for providing a pressure resistant layer of flexible pipe using adjacent hoop elements. In particular, but not exclusively, the invention relates to interlocking helically wound adjacent windings of ribbon or adjacent discrete hoops arranged in a side-by-side configuration to thereby form a carcass and / or pressure armor layer of a flexible conduit. Background technique [0002] Traditionally, flexible pipelines are used to transport produced fluids, such as oil and / or gas and / or water, from one location to another. Flexible pipes are particularly useful in connecting subsea locations (which may be in deep water, eg, 1000 meters or more) to sea surface locations. The pipe may have an inner diameter typically up to about 0.6 meters (eg, diameters may range from 0.05 m up to 0.6 m). Flexible pipe is generally formed as an assembly of a flexible pipe body and one or more end fittings. The pipe body ...
