CA 2174407

Casing spacers for isolating carrier pipe mechanically, galvanically, and chemically from pipe casings. The spacers may be attached using fasteners to pipe joint restrainers or other ring structures which encircle carrier pipe. The spacers are more efficient to install in the field, provide robust mechanical structure and physical stability which does not degrade over time, provide additional protection to the pipe joints, and, because they may be attached to conventional structures instead of requiring an integral ring structure for encircling a pipe, alleviate the distribution and inventory problems encountered by conventional systems in which the casing spacer runners are attached to an integral ring structure which must conform to the carrier pipe size and the casing inner diameter.
