ABSTRACT:
A centering support for a double-containment pipe assembly is adapted to support a plurality of primary pipes within a single containment pipe. A first support half of the centering support defines a plurality of first curved support surfaces for supporting one or more primary pipes, wherein each first curved support surface is defined by a radius greater than or equal to the outside radius of the primary pipe to be supported by the respective support surface. A second support half of the centering support similarly defines a plurality of second curved support surfaces for supporting one or more primary pipes, and each second curved support surface is defined by a radius greater than or equal to the outside radius of the primary pipe to be supported by the respective support surface. Fasteners are used to join the first support half to the second support half and move the first and second support halves toward each other, to in turn move the first and second curved support surfaces toward the respective primary pipes and fix the primary pipes within the containment pipe.
