"GOVERNMENT RECOGNISED STAR EXPORT HOUSE"
Flanges for Data Center Cooling Systems
At Neon Alloys, we understand that data centers run on uptime, and uptime depends on cooling infrastructure that simply cannot fail. Industrial flanges for data center cooling systems form the connective backbone of every chilled water loop, condenser water line, HVAC network, and cooling distribution unit (CDU) that keeps mission-critical IT infrastructure within safe operating temperatures. As an ISO 9001:2015 certified manufacturer and Government Recognised Export House, Neon Alloys engineers precision flanges to ASME B16.5, ASME B16.47 (Series A & B), DIN, EN 1092-1, and MSS SP-44 standards, delivering leak-proof, high-integrity joints for cooling towers, chillers, heat exchangers, pump rooms, CRAH units, and server room piping. With more than 20 years of manufacturing experience and an export footprint spanning 40+ countries, Neon Alloys supplies EPC contractors, MEP contractors, and data center project developers with flanges built for continuous, uninterrupted operation.
Every joint in a data center cooling loop is a potential point of failure, so material selection and dimensional accuracy matter just as much as pressure rating. Our flange range, including weld neck, slip-on, blind, socket weld, threaded, lap joint, orifice, and spectacle blind flanges, is available in stainless steel (304/304L, 316/316L, 321/347, 904L/254 SMO), duplex and super duplex steel (S31803, S32205, S32750, S32760), carbon steel (ASTM A105, A350 LF2, A694 F42/F52/F60), alloy steel (F11, F22, F91), nickel alloys (Inconel 600/625/825, Monel 400, Hastelloy C276/Alloy 20), and titanium Gr. 2. Sizes range from ½" (DN15) to 60" (DN1500) across pressure classes 150# to 2500# and PN ratings PN10 to PN100, giving HVAC contractors and cooling system integrators a single, reliable source for both standard and custom flange manufacturing.
What Are Data Center Cooling Flanges Used For?
Industrial flanges provide bolted, gasketed, leak-tight connections in piping systems that would otherwise need permanent welded joints. This allows maintenance, inspection, and system expansion without cutting pipe. In data center cooling applications, flanges join sections of chilled water, condenser water, and HVAC piping at equipment interfaces where periodic disassembly is required. A correctly specified flange prevents leaks under thermal cycling and pressure fluctuation, which matters most in facilities where even a short outage carries real operational and financial cost.
Applications in Data Center Cooling Systems
Neon Alloys flanges are engineered for secure, leak-free joints across every major cooling touchpoint in a data center:
Cooling Towers
Condenser water inlet/outlet connections
Chillers
Chilled water supply and return piping
Heat Exchangers
Plate and shell-and-tube connections
Pump Rooms
Primary and secondary loop piping
CRAH Units
Chilled water distribution to computer room air handlers
Server Room / CDU Piping
Cooling distribution unit connections
Covers chilled water, condenser water, HVAC, CDU, and district cooling piping networks.
