Kwik-ZIP HDX65 casing spacers were recently utilised for the South Grafton PS Outfall Pipes project.

The project required two 30m lengths of DN375 M-PVC carrier pipe to be installed inside a DN600 Mild Steel Casing. With the two pipe runs not being grouted after installation, the strength and durability of kwik-ZIP HDX Spacers are ideal for supporting the combined pipe/water weight once commissioned.  

Kwik-ZIP model HDX 65 spacers were selected and installed at 1m intervals to support the carrier pipe and protect it from abrasion damage during installation for both sections.   

Kwik-ZIP’s spacers have no metal parts and are made from Acetal POM – a high-grade thermoplastic that is flexible, extremely tough and has a low coefficient of friction. The spacers’ simple and efficient installation process requires no special tools.    

Kwik-ZIP HDX Spacers are approved by WSAA and meet the requirements of their Product Specification, PS-324 Casing Spacers.

According to Michael Allen, Project Engineer for Ledonne Constructions, kwik-ZIP’s client for the project, said that the product’s simplicity was what made it successful.

“Kwik-ZIP products are simple and quick to install, and ensure the carrier pipe is appropriately protected from abrasion and other damage during installation. Minimal force is required during installation of the carrier pipe due to the product’s low coefficient of friction.”
