On a recent Rail Infrastructure Alliance project in Sunbury, Australia, horizontal and directional drilling (HDD) specialist contractor, Jelmac Directional Drilling, utilised Kwik-ZIP HDX-90 spacers to assist facilitate the sliplining of a 355 mm HDPE carrier pipe over a 66 m run.
Kwik-Zip spacers were specified at 1.5 m intervals for this project as per Melbourne Water Retailer Agencies (MRWA) standards. 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 works were successfully completed at night due to stakeholder requirements.
Kwik-ZIP’s large range of spacers caters to a wide range of carrier/casing pipe size combinations as well as providing flexibility to deal with project alterations.
“Kwik-ZIP spacers are simple and quick to install and assisted with the sliplining process” said Mick Hemer, Operations Manager – Jelmac Directional Drilling.
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.
The spacers have no metal parts and are made from the company’s engineered thermoplastic blend that is flexible, extremely tough and has a low co-efficient of friction.
