A suspended pipe assembly comprising a first suspended pipe, a second suspended pipe, a third suspended pipe, and a number of suspenders for suspending the pipes from an elevated pipe or pipes of a mobile irrigation system or other fluid distribution system. The first suspended pipe and second suspended pipe are connected together via a fixed joint. The second suspended pipe and third suspended pipe are connected together via a live joint such that the second suspended pipe and third suspended pipe can expand longitudinally relative to each other. Additional suspended pipes can be connected to each other via alternating fixed and live joints. The suspenders allow the suspended pipes to expand longitudinally relative to the elevated pipe and prevents the suspended pipes from warping side-to-side.
