Project: Western Outer Ring Main (‘WORM’) – Buried Gas Transmission Pipeline Project
Location: Victoria

Carrier Size: 508mm OD high-strength steel line pipe with an external epoxy coating
Casing Size: Various – Crossing dependent
Run Length: Approx 500m of cased crossings
Spacer Model: HDX-38’s, HDX-125 and HDXT-63’s

The Western Outer Ring Main project in Victoria is a pipeline installation project that involved installing a 51-kilometre-long high pressure gas transmission pipeline.

It will address a key capacity constraint in the VTS by providing a new high-pressure connection between existing sources of natural gas supply in the north and east with those in the west of the state.  The entire length of the project involves 508mm diameter pipe being buried at a minimum depth of 900mm. 

Several different Kwik-ZIP spacers (HDX-38’s, HDX-125 and HDXT-63’s) where utilised on different cased crossings along the pipeline route. 

As well as assisting with the slip lining process as a result of the spacer runner system having a very low co-efficient of friction, Kwik-ZIP’s all thermoplastic design ensures that the pipes protective coating is not damaged during installation as the runners ensure that the pipe can’t make contact with the enveloper during and after installation.

Kwik-Zip’s large range of spacers cater for a wide range of carrier / casing pipe size combinations as well as providing flexibility to deal with different project requirements.   

kwik-ZIP’s HDXT & HDX Series spacers have been successfully appraised by the Water Services Association of Australia (WSAA) with both products the only casing spacers on the market that have been approved as compliant by WSAA. 

The WSA PS-324 Product Specification prescribes casings spacer requirements for correct protection of carrier pipes when installed inside casings.
