A centering support for a double containment pipe assembly consists of a three-piece assembly including an outer ring and a pair of mirror-image inner rings having tabs which are inserted into holes in the outer ring from opposite sides. The diameter of the outer ring is slightly smaller than the inner diameter of the outer pipe or conduit of the double containment pipe assembly and is inserted into an outer pipe at spaced locations therealong. The inside diameter of the inner rings are slightly wider than the outside diameter of the primary or inner pipe and they may receive therethrough the inner pipe. The inner rings and outer ring can be formed from dissimilar materials which are weldable to the outer pipe and inner pipe, respectively, at selected support points.
