316 Stainless Steel Square Liquid Cooling Pipe
The 316 stainless steel square liquid cooling tube is made of high-quality 316 or 316L stainless steel, specially designed for high-density liquid cooling cooling systems. Its square cross-sectional structure enables efficient heat conduction within a limited space. Combined with the excellent corrosion resistance of 316 stainless steel, it can operate stably for a long time in harsh environments such as fluorine-based cooling fluids and high salt spray. The product is formed through precise cold rolling, laser welding and solution heat treatment processes, ensuring no leakage risk for the tube body and suitable for high-end cooling scenarios such as data centers, AI supercomputing, and new energy storage.
Product Introduction
Product features
1. Super corrosion resistance
With 2-3% molybdenum content, a dense passivation film is formed. In an environment with chloride ions, the pitting corrosion rate is less than 0.005mm/a, and the service life is more than 10 times that of 304 stainless steel, avoiding the risk of hardware damage due to corrosion leakage.
2. High pressure-bearing and fatigue-resistant design
Using a multi-layer woven structure and pulse laser welding technology, the pulse life reaches 10⁶ times. It can withstand a continuous pressure of 1.5MPa and high-frequency vibration. The service life exceeds 8 years, and the maintenance cost is reduced by 60%.
3. Precise thermal compensation capability
The pipe body is reserved with an axial expansion/contraction amount of ±30mm, which can compensate for the thermal deformation caused by an 80℃ temperature difference in the liquid cooling system, preventing interface stress concentration from tearing, and ensuring the long-term stable operation of the system.
4. Ultra-clean manufacturing process
Produced in a ten-thousand-level clean workshop, it undergoes triple treatments of ultrasonic cleaning, acid washing and passivation, and electrolytic polishing. The inner wall roughness is Ra ≤ 0.4μm, and the particle residue is ≤ 10 per mL, meeting the semiconductor-level clean standards.
5. Modular quick installation
Provides solutions such as UQD/NVQD quick connectors and prefabricated ring network pipelines. The on-site installation time is shortened by 70%, and it is compatible with mainstream liquid cooling architectures such as GB300 and Microsoft Azure.
Application
Data center liquid cooling system
Used for the secondary-side coolant transmission of server cabinets, it addresses the heat dissipation bottleneck of high-density computing equipment and has been widely applied in AI clusters such as NVIDIA GB300 and Google GCP.
New energy energy storage thermal management
Suitable for the liquid cooling circuits of lithium battery Packs, it can withstand electrolyte corrosion and outdoor environments, ensuring the efficient operation of energy storage systems within the temperature range of -30℃ to 60℃.
Optical module precise cooling
Provides a micro corrugated tube connection solution for 800G/1.6T optical modules, meeting the requirements of fluorinated liquid cooling, high pressure, and long lifespan. Leading enterprises such as Zhongji Xuguang have adopted it in large quantities.
Industrial equipment cooling
Applied to oil-cooled/water-cooled systems of equipment such as laser cutting machines and CNC machines, it has wear-resistant and impact-resistant properties that extend the service life of the equipment by more than 30%.
