Project: Trenchless Water Main Installation
Location: Badgerys Creek, NSW

Carrier Size: 813mmOD Steelmains Sintakote
Casing Size: 1026mmID RC Jacking pipe (Humes C4 FJP)
Run Length: 180m
Spacer Model: HDX-90 (90mm high)

On a recent Water Main installation project in Badgerys Creek NSW, Sydney Water contractor Quickway utilised Kwik-ZIP HDX-90 spacers to facilitate the slip-lining of an 813mmOD Steelmains Sintakote carrier pipe over a 180-metre run.

Kwik-Zip spacers were installed at 2m intervals for this project as per Sydney Water specifications.  Carrier pipe weights were significant at 240kg/m empty and approximately 700kg/m when in service.

Kwik-ZIP’s large range of spacers caters for a wide range of carrier / casing pipe size combinations as well as providing flexibility to deal with project alterations.

The HDX’s unique load sharing design maximises the load bearing capacity of each runner and reduces point loading. The simple and efficient installation process does not require any special tools.  Kwik-ZIP spacers have no metal parts and are made from Kwik-ZIP’s engineered thermoplastic blend that is flexible and extremely tough. Its low co-efficient of friction also minimises the installation forces for large bore pipes.
