Haughton Pipeline Duplication Townsville

Haughton PipelineProject: Haughton Pipeline Duplication Townsville
Carrier Size: DN1800 GRP
Casing Size: DN2100 RC Jacking Pipe
Run Length: 54m & 120m
Spacer Model: HDX-90 (90mm high)

As part of the 36km Haughton Pipeline Duplication Project Kwik-ZIP HDX-90 spacers were used to facilitate the slip-lining of DN1800 GRP Carrier Pipe at 2 locations – a 54m crossing of Woodstock Giru Rd at Majors Creek and a 120m crossing of the Flinders Hwy / Great Northern Railway at Toonpan.

Kwik-Zip spacers were selected for this project due to their ability to protect and support the carrier pipe during the slip-lining process. As the pipes were not being grouted after installation the spacers also need to support the weight of the pipe and water for the life of the installation.

The weight of the DN1800 carrier pipe was 400 kg/m during installation and over 3,000 kg/m when full of water. Due to the weight of the pipe and water the kwik-ZIP spacer rings were installed at 0.5m intervals.

Haughton Pipeline

This highlights the HDX spacers exceptional load capabilities. As well as their ability to support heavy carrier pipe installation on low friction wear pads that resist abrasion from the casing pipe surface.

The HDX’s unique load sharing design maximizes 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, extremely tough and has a low co-efficient of friction.
