Why Stainless Steel in Data Centers?
Precision stainless steel manifolds, tubing & fittings solutions built for high-density cooling infrastructure.
Exceptional Durability and Pressure Handling
Modern liquid-cooled racks can exceed 100 kW, requiring robust piping systems capable of handling higher flow rates, pressures, and temperature variations. Steel provides high mechanical strength, resisting warping, cracking, and degradation over time compared to polymers.
Superior Corrosion Resistance
Stainless steel, especially grades like 316L, provides excellent resistance to corrosion from specialised coolants (e.g., glycol-based solutions). It eliminates rust and contamination issues common with carbon steel or inferior metal pipes, protecting sensitive cold-plate microchannels.
Long-Term Reliability & Lower Maintenance
Although initial costs are higher, stainless steel systems have longer lifespans and require less maintenance, making them more cost-effective over the full life cycle of the facility.
Optimal Space Optimisation
As rack densities rise, space for infrastructure is limited. Steel enables custom fabrication, including headers and compact designs that minimise welds and fit into tight, densely packed server environments.
Leak Prevention in Mission-Critical Areas
With downtime costs for large data centres averaging thousands of dollars per minute, the risk of a leak in the "white space" (where IT equipment sits) is unacceptable. Stainless steel provides long-term reliability and leak-tightness for critical cooling infrastructure.
Sustainability and Recyclability
Modern data centers are using electric arc furnace (EAF) steel, which uses recycled scrap as its primary input, making it a sustainable choice that supports circular economy goals.
