Fracturing fluid delivery systems with sacrificial liners or sleeves

A flexible fracturing fluid conduit comprising:

• a flexible body;
• a first rigid end coupled to a first end of the flexible body and a second rigid end coupled to a second end of the flexible body such that the first rigid end and the second rigid end are at opposite ends of the flexible fracturing fluid conduit, wherein the first rigid end includes a socket and an annular retention shoulder, wherein the annular retention shoulder has an inner diameter that is less than an inner diameter of the socket;
• a bore of the flexible fracturing fluid conduit extending through the first rigid end, the flexible body, and the second rigid end;
• and
• a sacrificial sleeve installed within the socket of the first rigid end of the flexible fracturing fluid conduit, wherein the sacrificial sleeve includes a head with a retention shoulder engaged with the annular retention shoulder.

A method comprising:

• inserting a rigid sacrificial sleeve into a socket of a rigid end of a flexible fracturing fluid conduit;
• and
• positioning the rigid sacrificial sleeve within the socket to engage a first retention shoulder of a head of the rigid sacrificial sleeve with a second retention shoulder located at an end of the socket;
• and
• coupling the flexible fracturing fluid conduit to fracturing equipment;
• and
• routing fracturing fluid through the flexible fracturing fluid conduit, wherein the rigid sacrificial sleeve inhibits erosion, by the fracturing fluid, of the flexible fracturing fluid.
