Abstract: A dual containment pipe assembly includes an outer containment pipe defining a rib on an interior surface thereof. An inner containment pipe can be positioned inside of the outer containment pipe. The inner containment pipe has at least one clip on an exterior surface thereof. At least one spacer wheel is between the outer containment pipe and the inner containment pipe. The spacer wheel has an inner channel for engagement to the clip and an outer groove for engagement to the rib. The spacer wheel includes: an inner circumferential hub defining the inner channel for engaging the clip; an outer circumferential rim defining the outer groove for engaging the rib; and a plurality of support spokes connecting the inner circumferential hub and the outer circumferential rim.
