Reinforced flexible pipe

摘要

A flexible conduit for transporting abrasive slurry, includes a flexible tubular body, such as rubber tube, and a plurality of wear-resistant rings provided in the body along the length of the conduit for protecting the inner surface of the body against abrasive action of the slurry, wherein at least one ring of the plurality of rings includes an indentation for engaging the tubular body in a form closed manner, and wherein the indention is arranged with the ring such that radial movement of the ring with respect to the conduit is prevented.

1. Flexible conduit for transporting abrasive slurry, comprising a flexible tubular body, and a plurality of wear-resistant rings provided in the body along the length of the conduit for protecting the inner surface of the body against abrasive action of the slurry, wherein at least one ring of the plurality of rings comprises one or more indentations for engaging the tubular body in a form closed manner, wherein the indention is arranged with the ring such that radial movement of the ring with respect to the conduit is prevented as well as release of broken parts of the at least one ring from the body into the slurry, wherein the indention is arranged with the ring such that the indentation faces towards an adjacent ring;
wherein the one or more indentations extend between a ring inner portion near the inner circumference of the ring and a ring outer portion near the outer circumference of the ring, wherein the radial plane cross-sectional area of the ring inner portion is greater than the radial plane cross-sectional area of the ring outer portion; and wherein the at least one ring co-axial with respect to the longitudinal axis of the conduit, so that a radial plane of the ring is perpendicular to said longitudinal axis.
