Our range of pipe casing spacers / insulators centre water and sewer pipes in casings. They are used to support and electrically insulate a pipeline from a casing pipe through which it must pass. The spacers are easy to install, are virtually corrosion proof, and provide insulating protection from a possible electrical shorting between the carrier pipe and casing. No special tools are required and they are easily applied by a single worker. The casing spacers eliminate the need to fill the casing annulus with sand and as they are so easy to remove, it allows damaged pipes to be repaired or replaced quickly. Let us know what your required runner height is (annular clearance between the inner pipe and the outer casing) and we will offer you a suitable solution for your pipeline.

Spacers are designed to support and cradle conduit for ease of installation, allowing optimal free flow of grout, thereby eliminating voids. Bore Spacers also maintain accurate duct position and alignment that will result in a reduction of installation time, isolation, boosting efficiency and ensuring that the installation is performed correctly. Features include:

• Multiple conduit sizes and designs
• Accommodates any type conduit or casing pipe
• Conduit to conduit separation to customer specification
• HDPE or polypropylene wheels with steel axle

Spacers

Spacers assist in installation of the piping system. We recommend that a spacer be used in each horizontal and vertical run of piping to adjust for dimensional piping differences. Spacers are available as filler flanges and ring spacers. Spacers can be machined in the field during system fit-up. This is important for existing piping systems where dimensions may have changed due to settling of foundations over the years.

Filler flanges are full face with drilled bolt holes and spiral groove phonographic finish on both sides for a good gasket surface. They match the pipe inside diameter and flange outside diameter. They are available in sizes 3″ through 30″ and thickness as required for system. We maintain a stock of 1/2″, 1″, 2″ and 3 ½” thick filler flanges in the different pipe sizes.

During field fit-up, tapered filler flanges can be used if mating flanges are not parallel.

Ring spacers match the pipe inside diameter and fit inside the flange bolt circle. They are available in 3″ through 30″ sizes in specific thicknesses or in a standard 12″ length. The standard 12″ length can be cut to the required thickness and machined with a gasket surface.
