CASING SPACERS - No metal parts

Casing Spacers - Casing Insulators - Wheel roller skids - Friction reducing


WA-Casing Spacers: (Bore Spacers, casing pipe isolation) isolate carrier pipes from the casing pipe. For pipe through pipe runs non-metallic casing spacers provide isolation between the carrier pipe and casing.

Roller wheels transfer sliding friction forces to the roller wheels.


Legs are concentric so carrier pipe roll during placement is less of a problem.

Eccentric roller wheel legs of different bottom or top length heights may also be supplied for a specific height requirements of the carrier pipe in the casing.

WA-non-metallic casing spacers applications include carrier pipes, through steel casing, PVC casing, GRP ducts and HDPE casing.

All American and International pipe and casing sizing.

Slightly irregular casing, or welding beads are better accommodated using roller runners.

Casing Spacers for large diameter pipes through casing

Casing spacers WA-DUO II models for large diameter carrier pipes - 7000 lb load support for each spacer.

Casing Spacers with wheel rollers - NO METAL PARTS


- Spacing: 1.5m
- Temp: -20 to 80 C working temperature
- Nylon closing bolts
- Material: HDPE Spacers
- Runner Width 240 mm
- Leg Heights: 32, 50, 70, 100, 160 mm




Casing spacer - WA-DUO-II models have four wheel clusters to carry the load. Insert forces are reduced by the roller wheels.

Casing spacers for pipe through casing or duct runs, position the carrier pipe with specific height runner legs.

The non-conductive wheel runners prevent metal to metal contact, providing electrical isolations and cathodic protection for the system. Pipe casing spacers position a carrier pipe inside a casing pipe and prevent pipeline coating damage.

Casing spacers WA-DUO-I model: with stainless steel strap bands:

Wheel runners allow a smooth transition across imperfections. Ideal for slip lining (slip-lining) and pipeline renewal.

Casing Spacers for large pipe tunnel projects may be constructed from stainless steel or carbon steel with wheel runner skids.

Casing spacers non-metallic wheel runners, large pipe weight supporting design for 7000 lb, each spacer.

Wheel runner legs low profile allow for a smaller diameter casing pipe to be used. Wheel runner casing spacers, are easy for crews to install, they do not require special tools or equipment.

Casing spacers WA-multi - roller wheel travelers

Casing spacers bundle design carry multi pipes through the same casing.

Casing spacers for multi pipe inserts through the same casing - HDPE Wheel Roller Spacers.


Combinations of smaller carrier pipes may be clustered together for placement through a casing pipe or duct.

Contact Westatlantic for proposed cluster carrier pipes required.



HDPE roller wheel casing spacers reduce friction. Bundles of carrier pipes through casing may have pipes of the same diameter or different diameters and may be non-metallic casing spacers or steel wheel spacers - or a combination of both.

Casing Spacers WA - BR Model - casing-spacers-small-diameter-pipes for small diameter pipe.

Casing spacers WA-BR models manufactured from HDPE materials, have no metal parts. Integrated reinforced heavy duty roller wheels, allow less friction during installation.

Use on carrier pipes 32 - 173 mm diameter pipe. Max static load support is 200 KG/leg. (441lb per leg)

Wheel runners also provide a smooth transition across welding beads or other low profile imperfections.

  • Skid heights available are 15, 25, 35, 45 mm lengths.

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



HDPE Physical Properties

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

Casing Pipe centralizer - WA vertical model applications


Light weight casing spacer for vertical pipe application.

Four strut spacer for vertical pipe/casing. The four wing spacer is equipped with wheel rollers and light construction material. Wing Spacers positions the conduit or pipe in a centralised position in the vertical casing.

All pipe sizes from 25 - 3000 mm



Casing spacers with wheel rollers are available for all pipe and pipe casing measures

Casing Spacers / Insulators are used for the protection of the carrier pipe when pulled or pushed inside a steel casing pipe.

Casing insulators with wheel runners provide easy installation of the carrier pipe inside the pipe casing, providing alignment (centering) of the carrier pipe in the pipe casing. 

Casing spacers for carrier pipes 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).
