Where are the kwik-Zip spacers being used and why?

The kwik-Zip spacers have been installed as part of the Waiari trunk watermain project located in Te Puke, Bay of Plenty, New Zealand. They have been installed around the circumference of a 710mm PE pipeline to ensure the newly installed PE pipeline will sit center, while pulling the pipeline through a 1040mm steel jacking pipe. By using the kwik-Zip spacers, HEB Construction have avoided any potential damage to the PE pipe on installation and protected against any future damage caused by the steel jacking pipe coming in to contact with the newly installed PE pipeline.

Why did we use the kwik-Zip brand product?

HEB Construction used the kwik-Zip brand due to the easy and quick installation with the screw lock system. This was key, due to the complexity of working below ground level. If the installation was to take longer or was more complex it could have created delays for the drillers pulling the pipeline through the jacking pipe, and therefore caused knock on delays for the project.

What intervals were they placed at? And why?

At either end of the jacking pipe, HEB Construction installed one kwik-Zip pipe spacer. The spacers were then installed at 2m intervals between each end, to avoid any sagging in the pipeline.

How have we found installing them? – did they work like we thought they would?

On site personnel were inducted into the correct way to install the kwik-Zip spacers using kwik-Zip’s installation guide, which ensured the product was used correctly and efficiently. The product worked exactly as it should and no issues were encountered. They were very quick and easy to install and HEB Construction would not hesitate in using them again should the situation arise.
