Abstract
There is disclosed a flexible pipe comprising a pipe body comprising first and second pipe layers. The pipe body delimits a bore for conveying a fluid, e.g., a fluid relating to oil and gas operations or mining operations, along the length thereof and the first pipe layer is disposed radially inward of the second pipe layer. The flexible pipe further comprises an end fitting to which a first end of the pipe body is connected. The end fitting comprises a tubular connector member concentric to the pipe body and disposed intermediate the first and second pipe layers. There is also a method of manufacturing a flexible pipe.

A flexible pipe comprising:
- a pipe body comprising first and second pipe layers, the pipe body delimiting a bore for conveying a fluid along a length thereof and the first pipe layer disposed radially inward of the second pipe layer;
- and
- an end fitting to which a first end of the pipe body is connected, the end fitting comprising a tubular connector member concentric to the pipe body and disposed intermediate the first and second pipe layers,
- wherein the first pipe layer extends into the end fitting over a length at least equal to a total length of an innermost surface of the end fitting, the innermost surface provided at least in part by the tubular connector member.
(canceled)
A method of manufacturing a flexible pipe, the method comprising:
- providing a pipe body comprising first and second pipe layers, the pipe body delimiting a bore for conveying a fluid along the length thereof and the first pipe layer disposed radially inward of the second pipe layer;
- providing an end fitting comprising a tubular connector member;
- and
- introducing the tubular connector member intermediate, and concentric to, the first and second pipe layers at a first end of the pipe body to form a connection of the pipe body to the end fitting,
- wherein the first pipe layer extends into the end fitting over a length at least equal to a total length of an innermost surface of the end fitting, the innermost surface provided at least in part by the tubular connector member.
