Critical Facilities
Cooling Loop and Critical Facility Flange Supply
Data center construction is one of the fastest growing sectors for industrial piping. Chilled water cooling loops dominate, with plate-cut lightweight flanges carrying the bulk of the work and forged ASME B16.5 at equipment connections.
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 plate-cut Class 125LW and AWWA C207 hub flanges in SA-516 Gr.70 across most of the system.
Process cooling water, makeup water, and condensate return round out the wet side. Forged ASME B16.5 Class 150 in A105 shows up at chiller and pump connections where the equipment specification calls for it, mixed with plate-cut 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. Forged or plate-cut, we ship both from the same warehouse.

Industry Challenges
What Procurement Has to Solve
- 01
Schedule compression that does not tolerate the lead times typical in heavier industrial service.
- 02
Mixing plate-cut Class 125LW patterns against forged 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.
