Casing Spacers / Insulators

We offer two ranges of pipe casing spacers / insulators: a custom-made range and an off-the-shelf range. Both types are used to support and electrically insulate a pipeline from a casing pipe through which it must pass. Typical uses include river, canal and bridge crossings, as well as road and rail crossings.

Bespoke range of spacers

The spacers are virtually corrosion proof, require no special tools and are easy and efficient to install. They are available with polymer runners or rollers which facilitate a reduction in the size of equipment needed and time spent installing the pipe. This, in turn, leads to huge cost savings.

Bore spacers

Bore 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:

Off-the-shelf range of spacers

This system of HDX spacers is available in four runner heights: 38mm, 65mm, 90mm and 125mm, which can be combined to achieve your required height. Benefits of HDX include:

End Seals

Our end seals are cheaper yet superior to the traditional, labour-intensive method of using bricks and mortar to  seal casing ends. Whilst soil stress and pipe movement cause mortar to crack, our products move with the pipe, ensuring the integrity of the seal. Different types of end seals are available meaning any combination of pipe sizes can be accommodated. Made of thick, seamless neoprene rubber which ensures excellent chemical resilience, each end seal comes with two easy to use, stainless steel fixing bands.
