AI Liquid Cooled Cooling Pipe

Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. extrudes this AI liquid cooled cooling pipe in 304 for deionized water loops, 316 for glycol mixtures above 60 °C, and nickel alloys like C276 or N06625 for two-phase immersion fluids or mixed-metal cooling circuits. Seamless construction eliminates the longitudinal weld — the most common leak path in shaped profiles — so every meter of tube carries the same structural integrity as every other meter, critical when a coolant leak inside a GPU rack is a six-figure event. Beyond square profiles, Ji lai da can produce L-profiles, T-profiles, hexagonal, and elliptical cross-sections to match any rack or manifold geometry — send the drawing and we confirm tooling feasibility. Each length ships with controlled bevel, consistent OD on the engagement face, and a pickled-and-passivated internal surface to ISO 8502 cleanliness standards, all documented on the EN 10204 3.1 MTC. As a factory-direct China manufacturer with ISO 9001 certification, we deliver mill-run pricing without trader markups under FOB, CIF, or DDP terms. With AI rack power climbing toward 250 kW, shaped seamless pipe has moved from specialty to volume buy. Send your drawing, target rack power, and coolant spec to Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. — tooling feasibility, a written quotation, and lead time returned the same working day.

No Seam, No Leak Path

A coolant leak inside a GPU rack is a six-figure event — ruined boards, lost training time, emergency shutdowns. Welded seams are potential leak paths; a longitudinal weld on a shaped profile is even harder to inspect reliably than on a round pipe. Extrusion eliminates the seam entirely: the metal flows around the mandrel and through the die in one press stroke, producing a closed profile with continuous grain structure and no joint. If you're running deionized water, 304 is sufficient. Glycol mixtures at 60 °C+ favor 316. For two-phase immersion fluids or mixed-metal loops, C276 or N06625 remove any corrosion concern.

End-Prep, Cleanliness, MTC

Most AI rack leaks originate not from the pipe wall but from the connection between pipe and manifold, the quick-disconnect on the rack door, or the seal inside the fitting. The AI liquid cooled cooling pipe from Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. is extruded seamless, so the tube itself never fails in service. At the tube end we deliver each length with a controlled bevel, consistent OD on the engagement face, and a pickled-and-passivated internal surface to ISO 8502 cleanliness — a defined particulate and hydrocarbon-free surface. End prep, cleanliness, and packaging are documented on the MTC per EN 10204 3.1.

Square Is Just the Start

Not every rack design uses a square tube. L-profiles for edge-of-board cooling, T-profiles for dual-flow-path architectures, hexagonal and elliptical profiles for specialized manifold geometries. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. can produce any closed or open cross-section that our extrusion press can tool — send the drawing and we'll confirm feasibility.

From Niche to Volume

Two years ago, single-rack power sat in the 20–40 kW band and air handling still covered most installs. The latest training clusters push 100 kW per rack today, with 130 kW and 250 kW reference designs on roadmap. Air cannot remove that heat density — the rack is liquid-cooled or the design loses. That shift makes the AI liquid cooled cooling pipe a volume buy rather than a specialty order. Operators building gigawatt-scale AI data center campuses are specifying shaped, unequal-wall profiles from the schematic stage, and the suppliers who can extrude the profile in one piece — rather than weld a formed sheet — are the ones on the bid list.

The TCO Argument

Take a 100 kW AI rack: air-cooled needs roughly 1.5× the fan power of the IT load and a chiller PUE around 1.45. Liquid-cooled drops the PUE to 1.10–1.15, cuts fan power to a tenth, and recaptures low-grade heat at 45–55 °C for district heating or absorption chiller pre-heat. On a 50 MW AI campus the annual operating cost difference is in the high single-digit millions of dollars, and the payback on additional piping capex is typically 18–24 months. Factory-direct China manufacturer pricing on the shaped tube is what makes that payback land inside the data center's standard refresh cycle.
