Problems solved by technology

[0008] Another problem with known protective layers is that the relative movement of the windings adjoining each other may cause wear of the windings over time
Abrasion can cause damage to the coil and eventually the flexible pipe body

Embodiment Construction

[0029] This manual introduces flexible pipes. It should be understood that flexible pipe is an assembly of a portion of a pipe body and one or more end fittings, the ends of the pipe body terminating in each end fitting. figure 1 One embodiment according to the present invention shows how the flexible pipe body 100 can be formed from the composite layered materials making up the pressure containing conduit. Although in figure 1 Several specific layers are shown in , but it should be understood that the invention is broadly applicable to composite pipe structures comprising two or more layers. Note also that the layer thicknesses shown are for illustration purposes only.

[0030] Such as figure 1 As shown, the tubular body includes an innermost carcass layer 110 and a pressure sheath 120 . The carcass 110 provides an interlocking metallic construction that can be used as the innermost layer to fully or partially prevent the internal pressure sheath 120 from collapsing due t...

Abstract

A method for manufacturing flexible pipe body and flexible pipe body of a type suitable for transporting production fluids are disclosed. The flexible pipe body includes an armour layer comprising interlocked windings of armour tape comprising at least one armour locating element and a reinforcement layer comprising a layer of reinforcement tape comprising at least one reinforcement locating element over the armour layer. The armour locating element and reinforcement locating element locate windings of the reinforcement tape with respect to respective windings of the armour tape.

Description

technical field [0001] The present invention relates to flexible pipes that can be used to transport fluids, such as product fluids and the like. In particular, but not exclusively, the present invention relates to flexible pipe bodies and a method for manufacturing flexible pipe bodies having one or more armor layers reinforced by a layer of reinforcing tape wrapped around the armor layer. Background technique [0002] Traditionally, flexible pipes have been used to transport product fluids such as oil and / or gas and / or water from one location to another. Flexible pipe is particularly useful when connecting a subsea location to another subsea location or a sea level location. Flexible pipe is generally formed as an assembly of a length of flexible pipe body and one or more end fittings. The pipe body is typically formed as layers of composite tubular material constituting the fluid and pressure containing conduit. The tube structure allows for substantial deformation wit...
