AI Technical Summary
Technical Problem
Traditional flexible tubes are prone to clogging due to increased temperature and pressure in deep and ultra-deep water environments, while existing inserts are difficult to manufacture on industrial scale and may lead to flexible tube failure.
Method used
A woundable insert is employed, with a cross-section including a curved first portion and a body portion, the main portion bridging the spiral gap between the carcass strips and preventing the insert from being separated in use by a special shape design.
Benefits of technology
Effectively reduces the risk of blockage of flexible tube holes, improves the smoothness of fluid flow, and prevents inserts from being separated during use, reducing manufacturing costs.

Abstract
Disclosed herein are an elongate strip element, a flexible pipe body, and a method of manufacturing a flexible pipe body, the elongate strip element having a cross-section comprising: a first portion extending from a first free edge of the elongate strip element corresponding to a first end of the cross-section of the elongate strip element, wherein the first portion is curved for positioning in a first gap region extending between two adjacent coils of a carcass strip of the flexible tube body; and a body portion extending between the first portion and a remaining end of the cross-section corresponding to a remaining free edge of the elongated strip element, having a length for bridging another gap region, and a further gap region extending between one of the two adjacent coils and another adjacent coil of the carcass strip adjacent the one of the two adjacent coils of the carcass strip, the intermediate region is curved for at least partially positioning into another gap region.
