kwik-ZIP ticked off several major projects in 2025.
In 2025 kwik-ZIP celebrated 25 years of operation and matched that landmark with impressive performance across key infrastructure projects. The company began the year with a clear focus on delivering quality, reliability and value in its spacer and centraliser systems and ended it ready for the next chapter.
For a quarter of a century, kwik-ZIP has been at the forefront of engineering innovation, transforming the way centralisers and pipeline spacers are designed and delivered across the globe. Over the last five years alone, more than three million kwik-ZIP units – spanning a range of sizes – have rolled out from precision injection molds, destined for projects on every continent.
This milestone year afforded the company a chance to reflect on its journey from a local Australian manufacturer into a global supplier of thermoplastic spacer and centraliser systems. During 2025 the company translated this foundational strength into tangible contributions on major infrastructure jobs all over the globe.
Down Under
In Western Australia, one of kwik-ZIP’s customers utilised HDXT-103 spacers with load inserts to facilitate the slip-lining of a 914mm Sintakote® mild steel cement lined (MSCL) carrier pipe into a 1399mm reinforced concrete jacking pipe casing, as well as a 1422mm Sintakote MSCL carrier pipe into a 1708mm casing for a rail crossing in Yanchep.
This installation was part of the of the larger Water Corporation Alkimos seawater desalination plant project, which will ultimately supply up to 50 billion litres of clean drinking water to millions of Western Australians each year.
In New South Wales, kwik-ZIP’s HDXT-153 spacers played a role in an important infrastructure upgrade. Here, contractor Vaughan Civil deployed the spacers to facilitate the slip-lining of two water main runs as part of the M1 Pacific Motorway extension project.
The M1 Pacific Motorway extension is a $2.1 billion project funded by the Federal and New South Wales Governments that, once complete, will feature a 15km extension of the Sydney–Newcastle motorway, along with the removal of five sets of traffic lights.
Vaughn Civil worked on runs of 62m and 127m and involving 1219mm outside diameter (OD) Sintakote Steel MSCL carrier pipes into 1574mm internal diameter (ID) GRP casing. Thanks to a unique load-sharing design, kwik-ZIP’s HDXT-153 spacers were used to centre and support the carrier pipe inside the host pipe during the slip lining process.
Europe
In the United Kingdom, kwik-ZIP demonstrated its prowess at the A465 Heads of the Valley project, which involved the extension and widening of a major transport corridor in Wales.
As part of this infrastructure upgrade, existing utility services required diversion. To this end, four new pipe crossings were installed through precast concrete tunnels beneath the roadway at Hirwaun. To ensure safe and efficient installation of the carrier pipes within these tunnels, kwik-ZIP HDXT-153 casing spacers were utilised across all four crossings.
The four crossings comprised of two crossings of 35m and 47.5m each of 711mm OD pipe into 1050mm ID casing, and two crossings of 35m and 47.5m each of 1118mm OD into 1500mm ID casing.
The use of kwik-ZIP HDXT-153 spacers ensured proper alignment and centralisation of the pipes within the tunnels, reducing friction during installation and protecting pipe coatings. The modular design of the HDXT-153 provided a reliable, corrosion-resistant, and load-bearing solution suitable for the project’s demanding conditions.
These are just a handful of many such infrastructure projects successfully executed in 2025 thanks to the guiding hand of kwik-ZIP. With established distributors in Australia, New Zealand, the United States and Great Britain, and countless runs on the board, it’s easy to see why kwik-ZIP has become a go-to infrastructure partner for pipeline projects around the world.
With its eyes fixed on further growth in 2026, kwik-ZIP’s 25-year-old story is one to keep watching.
