Every data centre runs on water as much as it runs on power. Behind each hall sits a network of chilled-water and condenser loops, pump manifolds, fire and stormwater mains and generator fuel lines, and increasingly that network is being built in heat-fused thermoplastic rather than metal. Industrial Plastics custom-fabricates this scope in HDPE and polypropylene for hyperscale, colocation and edge facilities. We are ISO 9001:2015 certified by SGS, weld to the German DVS 2207 standard, and have been fabricating in Brisbane since 1971, there’s no better fit for building out Australia’s future data centre cooling pipework.
Southeast Queensland is in the middle of a data centre buildout driven by AI and high-density compute. Australia’s deployable capacity is forecast to more than double, from around 1,350 MW in 2024 to over 3,100 MW by 2030, and a meaningful share of that pipeline is landing in SEQ. As cooling and water demand rises, engineers are specifying heat-fused thermoplastics over metal for the water-side and utility infrastructure.
Why data centre engineers choose Industrial Plastics
Leak-tight fused joints
Water is the enemy of IT equipment. HDPE is joined by butt fusion and electrofusion into one continuous, homogeneous run. A joint made to a qualified procedure is as strong as the pipe wall, removing the mechanical couplings and gaskets that are the usual leak paths. Our welders are qualified to DVS 2207.
Corrosion-free and low-loss
HDPE is chemically inert. It will not rust, scale or tuberculate, so it protects water quality and heat-exchanger performance. PE100 pressure pipe is designed on a 50-year basis with an expected service life well beyond 100 years, and its low thermal conductivity reduces loss and surface condensation on chilled lines.
Prefabricated, site-ready
We fabricate numbered spools off site with data-logged fusion records, material certificates and hydrostatic test reports issued before delivery. On congested data centre sites this de-risks every joint, cuts field labour and lifts the pipework off the critical path.
What we fabricate for data centres
- External and underground chilled and condenser water loops, large-diameter PE100 (commonly DN315 to DN800+) between cooling towers, chillers and plant rooms
- Pump skids and header manifolds with reducing tees, sweep bends and flanged outlets, dimensionally checked on the bench
- Site water, fire-water loops and stormwater mains
- Double-containment HDPE generator fuel lines, carrier and containment fabricated and tested as one unit
- Higher-temperature indoor secondary loops in polypropylene (PP-R / PP-RCT)
Material selection guide for data centres
| Material | Typical data centre duty | Notes |
|---|---|---|
| HDPE (PE100) | Chilled and condenser water, site, fire and stormwater, double-containment fuel | Fabricated up to DN1200. AS/NZS 4130 pipe, AS/NZS 4129 fittings |
| Polypropylene (PP / PP-R) | Higher-temperature secondary and technical cooling loops | Extends beyond HDPE’s temperature envelope. Welded to DVS 2207 |
| PVDF and PVC | Chemical dosing and treated-water duties | High purity and chemical resistance, engineer-specified |
Where HDPE stops: the data hall white space
HDPE is a combustible polyolefin, so it is used for site, underground, plant-room and external cooling infrastructure rather than exposed inside the data hall. Under-floor and above-ceiling air plenums require limited-combustibility materials meeting the 25/50 flame-spread and smoke-developed limits (ASTM E84), alongside the data centre fire-protection standards NFPA 75 and NFPA 76. For higher-temperature indoor secondary loops, polypropylene (PP-R / PP-RCT) extends the envelope beyond HDPE, and flame-retardant PP grades exist, though a flame-retardant additive is not the same as a plenum listing. The in-hall liquid-cooling loops at the rack and CDU remain predominantly stainless steel with EPDM flexible drops. We fabricate the thermoplastic scope and advise honestly where it ends.
Representative projects
We have fabricated custom tanks, pipework and process equipment in Brisbane for over five decades, for clients including Rio Tinto, BHP, Veolia, Origin Energy, Glencore and Goodman Fielder. The documented welds, material traceability and ITPs those projects demand are exactly what hyperscale operators and their mechanical consultants, including Aurecon, Arup, AECOM and Jacobs, require on a data centre package.
