Material Selection: Your Manifold Material Choice Determines System Reliability
Why Material Selection Matters
Liquid cooling is now baseline infrastructure in hyperscale data centres due to AI, GPU, and HPC deployments exceeding air cooling limits. Liquid cooling loops have become long life infrastructure assets, with reliability expectations comparable to mechanical plant systems.
Manifolds sit at the interface between facility plant, CDUs, and rack‑level cooling hardware, meaning the material directly affects hydraulic performance, leakage risk, QA, and long term system stability
Steel: The Clear Choice for Data Centre Manifolds
Strength & Dimensional Stability
Stainless steel maintains uniform wall thickness and predictable hydraulics, ensuring stable flow paths even under demanding operating conditions.
Weld‑qualified joints
ASME‑qualified welded manifolds (Section IX, B31, BPE) deliver metallurgical continuity, support NDE inspection, and provide full hydrostatic testing and traceable documentation.
Fewer Joints & Lower Leak Risk
Steel can be bent and formed for complex routes, reducing the number of joints, and therefore reducing potential leak points in mission critical cooling.
High Flow Integrity
Consistent geometry and smooth internal surfaces support efficient flow, enabling predictable system hydraulics for HPC and AI workloads.
Pressure & Temperature Stability
Steel retains mechanical properties under warm water cooling, elevated flow velocities, and continuous pressure cycling typical of modern high‑density liquid cooling.
Chemical Compatibility via Passivation
Passivation to ASTM A380/A967 forms a self‑healing chromium‑oxide layer, enhancing corrosion resistance and long‑term system reliability.
The Tate Difference
Proven Delivery at Scale
Over 1 GW of liquid cooling piping delivered for hyperscale, high‑density deployments.
Modular, Pre‑Fabricated Steel Systems
Schedule 10 stainless‑steel manifolds, fully pre‑fabricated, pressure tested, and verified off‑site with complete quality documentation.
Optimised for Fast Track Builds
Flanged modular assemblies install quickly with no field welding, reducing programme risk and site hours.
Engineered for High Density Cooling
Steel delivers predictable, stable performance with cleaner routing, fewer joints, and long‑term reliability under thermal and pressure cycling.
For assured performance and long term stability, stainless steel remains the most trusted material for mission critical data centre cooling.
