ABSTRACT:
A centering support for a double-containment piping assembly has a body portion including an inner surface defining a central aperture for receiving and supporting the inner pipe within the outer pipe, and the inner surface is defined by a first radius of curvature. A plurality of support lugs are spaced apart from each other and project outward from the body portion, and each support lug defines an outer support surface for contacting the outer pipe. The support lugs also define corresponding recessed surfaces extending between adjacent support lugs, and each recessed surface is defined by a second radius of curvature substantially concentric with the first radius of curvature.
