Casing spacers

CASING SPACERS - Wheel Roller Wheels - HDPE metal parts

Friction reducing wheel rollers standard.


WA-NM-CS Casing Spacers/Insulators, provide cathodic protection.

HDPE (high-density, polyethylene) material support weights up to 7000 lb per casing spacer. Sizes to fit all American and International pipe.

Friction reducing roller wheels allow the carrier pipe to travel through a casing with less resistance. Roller wheel casing spacers transfer sliding friction to the roller wheels.

All legs are equal lengths, making roll moments less of a factor during installation.


Placement of carrier pipes through casing.

Casing spacers supported and positioned pipe inside a casing pipe.

Casing Insulators prevent damage to the outer coated surface of a pipeline during installation.


Easy Installation: wheel rollers provide minimal coefficient of friction allowing the carrier pipe to more easily pulled through the casing.

Cathodic Protection: with low moisture absorption of the polyethylene material.

Casing spacer - WA-DUO-II models have four wheel runners to support heavy loads. Insert forces are reduced by the roller wheels.

Casing spacers for pipe through casing or ducts, position the carrier pipe in the casing with specific leg heights.

The non-conductive wheel runners provide cathodic protection.

Casing spacers WA-multi-pipe carriers - with roller wheels

HDPE Casing Spacers - No metal parts

Casing spacers WA-NM-MP non-metallic units carry pipe bundles of several small diameter pipes through the same casing.

Seperating holding pods keep each pipe isolated in the bundle, friction reducing HDPE wheel rollers assist with the installation.multi-pipe-through-same-casing-spacers-with-wheel-skids

Different diameter carrier pipes may be clustered together for placement through the same casing pipe or duct.

Installation Guide WA-R casing spacers

Casing Spacers - casing-spacers-small-diameter-pipes for small diameter conduit through casing.

Casing spacers WA-NM-BR models with roller wheels are non metallic HDPE material. Integrated reinforced heavy duty roller wheels provides less friction during installation.

WA-NM-BR units are used on carrier pipes 2" - 6" / 32 - 173 mm diameter pipes. Max static load support is 200 KG/leg. (441lb per leg)


Slip lining new pipe through existing pipes are facilitated by low profile non-metallic-casing spacers.

Wheel runners provide a smooth transition across low profile imperfections.

  • Leg lengths available are 15, 25, 35, 45 mm high.

Additional pipes may also be attached to the main spacer allowing for a multi pipe configuration.

Top space for this configuration is required.

HDPE Physical Properties

Casing spacers Stainless steel, for applications that require metallic solutions.

Casing spacers with wheel rollers are available for all pipe/casing sizes.

Casing Spacers / Insulators protect the carrier pipe when they are pulled or pushed inside a casing pipe.

Casing insulators with wheel runners provide easy installation of the carrier pipe inside the pipe casing. They provide alignment of the carrier pipe through the pipe casing. 

Casing spacers clamp fasten on all pipe types; PE, PVC, STEEL, DI or CONCRETE. Casing spacers protect pipe coatings and are normally installed without using specialized tool.


Casing spacer Information required

To order a casing spacer for a pipe/casing the following information is required:

Outer diameter (OD) of the carrier pipe

Inner diameter (ID) of the casing pipe

Casing Spacer material required: Stainless, Galvanized, Carbon steel, non - metallic.

Other information relevant to the application (e.g. weight of the pipe, leg height see standard heights for each model etc).
