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.
Claims5
A support for a double-containment piping assembly having inner piping mounted within outer piping, comprising:
- an inner body portion for coupling to the inner piping, and an outer body portion spaced apart from and surrounding the inner body portion for supporting the inner piping in a spaced apart relationship with respect to the after piping and a plurality of support legs extending between the inner body portion and the outer body portion, the support legs being spaced relative to each other and defining a plurality of flow channels between the support legs for fluid flow through the support, each support leg being defined by a first convex curved surface extending between the inner body portion and the outer body portion and a second concave curved surface located on a substantially opposite side of the support leg relative to the first curved surface and extending between the inner body portion and the outer body portion.
