Apparatus and method comprising a well conduit system 1 comprising inner 3 and outer 2 concentric conduits, the conduits defining an annular space 7 through which radial loading surfaces or supports 6 extend. The supports extend from one of the conduit and abut against the other. The supports are longer than the annular distance between the conduits such that the conduits are in a pre-stressed state when concentrically arranged. The arrangement allows hoop stress resistances to be shared between the two conduits to form a greater effective wall thickness and therefore increasing the systems pressure bearing capacity. |
