Casing spacers

CASING SPACERS - Friction reducing Wheel Rollers

Pipe in Pipe Installation

WA-HDPE-CS spacers hold the carrier pipe off the bottom of the casing.

Friction reducing roller wheels assist travel through the casing with less resistance. The roller wheels transfer sliding friction forces to the roller wheels.

All legs are even spaced may be even height or combination of height selection depending on pipe casing measures.

High impact strength HDPE casing spacers move the carrier pipe through the casing pipe with standard leg heights.


WA-HDPE-CS Casing Spacer/Insulators, provide cathodic protection. they support up to 7000lb. per spacer.

All legs are the same hight, allowing the carrier pipe to always maintain its position in the casing. Carrier pipe roll tendencies is less of a factor when all legs are concentric.

HDPE casing spacers are available for all American and International pipe diameters.



  • · Uniform support for the weight of the pipe
  • · Electrical Insulation
  • · Corrosion Protection
  • · Keeping the carrier pipe and casing separate



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

  • High Compression Strength.
  • Low Co-efficient of friction
  • Tensile Strength ~5000-7500 psi
  • High Impact Strength 
  • High Hardness Level 
  • Uniform Support to Weight Of Pipe
  • Weather resistance
  • Chemical resistance
  • Electrical Insulation
  • Dimensional Stability
  • Corrosion Protection
  •  Keeping the carrier and casing pipe separate

Casing spacers for multi pipe bundles - with with friction reducing roller wheels

HDPE Casing Spacers - No metal parts

Casing spacers WA-NM-MP HDPE units carry smaller pipe bundles through the same casing pipe.

Holding separators keep each pipe spaced apart in the bundle. Friction reducing HDPE wheel rollers reduce friction during installation.multi-pipes-through-same-casing-spacers

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

HDPE Physical Properties

See 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, DIP or CONCRETE. Casing spacers protect pipe coatings and installed without specialized tools.


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).
