A slip-lining champion

Contracting company Rob Carr turned to kwik-ZIP for its project in Gosnells, Western Australia, and used its spacers to facilitate the slip-lining of a wastewater pressure main.

kwik-ZIP’s DNA is made up of versatility, simple installation and ease of use for contractors.

And it was because of these traits that contracting company Rob Carr turned to kwik-ZIP for its project in Gosnells, Western Australia.

The kwik-ZIP HDXT-103 spacers were installed to facilitate the slip-lining of a mild steel cement mortar lined (MSCL) wastewater pressure main into a RC Jacking pipe, running under a rail line for the Gosnells Main Pumping Station Wastewater Pressure Main Realignment project. 

Rob Carr Project Manager Marie Piette saluted kwik-ZIP and its innovative spacers.

“The MSCL pipes insertion is making good progress despite a challenging environment, with production efficiency notably enhanced by the simplicity of installation of the kwik-Zip spacers,” Piette said.

The simple and efficient installation process did not require any special tools or any requirement to pre-wrap the pipe. 

kwik-ZIP spacers have no metal parts and are made from the company’s engineered thermoplastic blend with high flexural strength, high temperature resistance, low co-efficient of friction, abrasion resistance and outstanding chemical resistance.

With integrated rubber grip pads under collars to prevent slippage, kwik-ZIP spacers load sharing suspension system allows heavy loads to be shared across multiple runners.

This reduces point loading and increases the overall load capacity of the spacer.

kwik-ZIP’s series of spacers caters to a range of carrier and casing pipe size combinations. It also provides contractors and installers flexibility to deal with project alterations.

In Australia, kwik-ZIP’s HDXT and HDX Series spacers have been successfully appraised by the Water Services Association of Australia (WSAA) against the requirements of WSAA product specification number PS-324 (casing spacers).

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

kwik-ZIP’s firm presence in the industry has come about through years of hard work. The company was established in 2000, following the development of the industry’s first patented non-metallic plastic bow spring centralisers.

Since then, kwik-ZIP spacers have been making waves in the industry, and the company has been producing and marketing centraliser and spacer products for wider use.

Over the years, the kwik-ZIP team has developed and been awarded patents on various other centraliser and spacer products for applications in many industries, from production drilling to trenchless pipeline installations.

Today, kwik-ZIP manufactures and supplies a centraliser and spacer system for a wide range of industry sectors including production well drilling, trenchless pipelines, horizontal directional drilling, ground engineering and the general civil and construction markets.

Like all of its products, the HDX/HDXT spacer system series are aligned with the kwik-ZIP’s ethos to provide simple, cost-effective, and high-quality solutions.

“kwik-ZIP is proud to be supplying products to such a well-respected Australian business in Rob Carr,” kwik-ZIP General Manager Paul Jeffreys said.

“Rob Carr is considered one of the pioneers in microtunnelling in Australia and a leader in utilities infrastructure construction.”
