Sleeve member, end fitting assembly and method of assembly of flexible pipe

摘要

A sleeve member, end fitting assembly, and a method of assembly of a flexible pipe are disclosed. The sleeve member includes a body comprising a substantially cylindrical portion having an inner diameter substantially equal to an outside diameter of a first pipe body layer for overlying the first pipe body layer; and a flange portion extending radially outwards from the body for locating between a further pipe body layer and an end fitting, the further pipe body layer being an armor layer, the flange portion having an outer diameter substantially equal to or greater than the outer diameter of the further pipe body layer.

主权项

1. A flexible pipe for transporting fluids from a subsea location, comprising a flexible pipe body and at least one end fitting assembly, wherein the at least one end fitting assembly comprises a collar member and a sleeve element, wherein the sleeve element comprises:
a body comprising a substantially cylindrical portion having an inner diameter substantially equal to an outside diameter of a first pipe body layer and overlying the first pipe body layer, wherein the body is made of a relatively harder material than the first pipe body layer; and a flange portion extending radially outwards from the body and located between a further pipe body layer and the collar member, the further pipe body layer being an armour layer, the flange portion having an outer diameter substantially equal to or greater than the outer diameter of the further pipe body layer; wherein the body is positioned relative to the first pipe body layer to prevent the first pipe body layer from extruding into a gap between the collar member and an adjacent end of the armour layer.
