WA-NMCS Casing Spacers/Insulators: are non-metallic HDPE (high-density, polyethylene) insulators that fit all American and International pipe sizes. Roller wheel friction reducing skids provide easy slip installation.

Roller wheel WA-NM Casing spacers transfer sliding friction forces to the roller wheels.

All leg lengths are concentric, making roll moments during placement less of a problem.

APPLICATIONS

For installation of pipelines when the carrier pipe runs inside a casing. They support carrier pipes within the casing, to electrically insulate the pipe from the casing and prevent damage to the coated surface of the pipe.

SCOPE OF APPLICATION

When a pipeline is buried in the ground, at underground road, river, railway and highway crossings, a pipeline is protected by casing.

The pipeline is supported and positioned within the casing by a Casing Spacer/Insulator. The Casing Insulator, electrically insulates the pipeline from the casing. This insulting function is necessary for the cathodic protection of the pipeline. casing insulators preventing electric current loss when the pipeline is used as a conduit for electrical cables. Casing Insulators prevent damage to the outer coated surface of the pipeline when the pipeline is drawn through the casing during installation.

GENERAL FEATURES

WA-NMCS casing Insulator are a high-density, polyethylene product, injection molded to provide an efficient insulator of highest quality. It offers the following general features:

(i) Easy Installation: wheel rollers provide minimal coefficient of friction that allows the carrier pipe to be more easily pulled through the casing thus helping in easy installation of the carrier pipe within the casing.

(ii) Cathodic Protection: Insulating properties like excellent dielectric resistance and low moisture absorption of the polyethylene material cathodic protection and yielding minimal electric current loss.

WA-NMCS casing insulators support static loads up to 7000 lb, using sizing models for large pipe. 300 lb and up load support models are also available for smaller diameter pipes.

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 carrier pipe to casing pip contact for electrical isolations and cathodic protection.

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

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-pipe carriers - with roller wheels

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

Holding pods keep each pipe separate in the bundle, friction reducing HDPE wheel rollers isolate the carrier pipes from the casing.
