Critical Facilities
Cooling Loop and Critical Facility Flange Supply
Data center construction is now one of the fastest growing sectors for industrial piping. Cooling loops dominate, with reliability and schedule outweighing nearly every other consideration.
Industry Overview
How Data Centers Piping Actually Looks
Chilled water and condenser water loops carry the cooling load from chillers and cooling towers to the CRAH and CRAC units on the data floor. Volume is high, pressure is modest, and the flange list runs to lightweight Class 125LW and AWWA C207 hub flanges across most of the system.
Process cooling water, makeup water, and condensate return round out the wet side. ASME B16.5 Class 150 shows up at chiller and pump connections where the equipment specification calls for it, mixed in with lightweight on the main runs.
Schedule is the constant. Data center projects do not slip waiting for flanges. Stocking depth and delivery reliability matter more than commodity price spread, and the spec sheet rewards a supplier who can move on the same week the drawings hit.

Material Selection
Common Materials and Why
ASTM A105
Standard carbon steel for chiller, pump, and equipment connections.
Carbon Steel Plate
Used in fabricated AWWA hub flanges for large cooling tower and main loop diameters.
316L Stainless

Industry Challenges
What Procurement Has to Solve
- 01
Schedule compression that does not tolerate the lead times typical in heavier industrial service.
- 02
Mixing lightweight Class 125LW patterns against ASME B16.5 Class 150 equipment connections cleanly.
- 03
Large diameter cooling water flanges where freight and storage at the construction site matter.
- 04
Future expansion provisions that require blind flanges and tie-in points designed in from day one.
