carrier 42 the outer braided shell 44 is slidably fitted over an outer surface of the inner fluid carrier along an entire length of the inner fluid carrier more specifically based on an internal pressure generated by a fluid substance traveling within the inner fluid carrier 42 the inner fluid carrier preferably made of a flexible material may expand radially and or longitudinally to accommodate an increased pressure of the fluid substance thus the outer braided shell 44 helps to maintain and protect a structural integrity of the inner fluid carrier 42 so that the internal pressure does not cause the carrier to swell outwardly and burst or to axially distend another important aspect of the present seismic joint system 10 is that the outer braided shell 44 is reinforced with a specific braiding formed of individual wires or threads or groups of individual wires or threads helically arranged on the inner fluid carrier 42 and having a predetermined braiding angle u03b1 relative to a longitudinal axis l of the pipe connector 40 such that the braiding angle u03b1 allows for both lateral and angular movement of the second inner and outer pipes 16 28 attached to the connector a detailed description of the braiding angle u03b1 is provided.
