Cracking the case21 January 2016
With the release of The Water Services Association of Australia (WSAA) code for governing spaces, contractors can no longer use make-shift casing spaces to centralise their pipe during installation.
Casing spacers are used for the protection of carrier pipes when installed inside casings. Many contractors have been using hand-made wooden spaces as a shortcut which, according to Jason Linaker of Kwik-ZIP, are simply too risky.
“Over time, timber rots away leaving either gaps in the grouting, or if grouting isn’t used, the pipe will move once the timber is no longer able to support the weight. There is also the risk with timber that it will wear away as it is run in,” says Jason.
“Although spacers are usually a small part of the overall pipe installation process, correctly designed and fitted spacers can significantly increase the life expectancy of the carrier pipe by keeping them free from corrosion, causing damage and overall wear,” he says.
Kwik-ZIP HDX Series Spacers are the only ready-made Australian product that complies with the new standards and are made from a high-grade thermoplastic material with integrated rubber pads for slip resistance.
On-site assembly of the Kwik-ZIP spacers is easy with no specialist skills required. “Flexibility of the design means various runner heights can be achieved, allowing for different pipe and casing combinations,” says Jason.
