Friction reducing installation - Wheel Rollers

Fits all American and International Pipe Sizes


Casing Spacers (Bore Spacers) isolate carrier pipes from the casing pipe.

Roller wheels transfer sliding friction forces to the roller wheels.

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

Casing Spacers (Bore Spacers) for large diameter pipes

Large Pipe Casing Spacers - Supports up to 7000 lb. each spacer.

Casing Spacers with wheel rollers



Spacing at 1.5M
-20 to 80 C working temperature
Nylon closing bolts
HDPE Poly Spacers
Runner Width 240MM
Leg Heights: 30, 50, 70, 100, 160mm



WA-DUO-II model models have four wheel truck skids to carry the load. Insert forces are reduced by the roller wheels.

Casing spacers position pipe in a casing with "specific height runner legs".

Non-Metallic Casing Spacers with wheel runner systems provide electrical isolation.

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

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

Wheel runners allow a smooth transition across weld bead joints and 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 carrie multi pipes through the same casing.


Multi pipe inserts through the same casing using HDPE Wheel Roller Spacers.


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

Contact Westatlantic for proposed cluster of carrier pipes. We will advise on a solution for the application.



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.

WA Vertical Casing Pipe centralizer


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

Wheel runner pipe insulators provide easy installation of the carrier pipe inside the pipe casing, providing alignment (centering) of the carrier pipe in the pipe casing. 

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


Information we require

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

  • Inner diameter of the casing pipe
  • Outer diameter carrier pipe
  • Casing Spacer material: Stainless, Galvanized, Carbon steel
  • Other information relevant to the application (e.g. weight of the pipe, insulation thickness, leg height see standard heights for each model etc).
