How To Prevent Leakage in Data Center Liquid Cooling Systems: The Role Of 316 And 304 Stainless Steel Pipes

The leakage problem of stainless steel liquid cooling pipes in data center liquid cooling systems is currently a major concern in the industry. The liquid cooling system relies on circulating cooling fluid to remove the heat generated by servers. The stainless steel liquid cooling pipes, as the key component for transporting the medium, if they leak, will directly affect the stability of the entire system. Leakage not only leads to a decrease in cooling efficiency but also may cause equipment short circuits, data loss, and even the shutdown of the data center, resulting in significant economic losses.

In actual operation, the causes of leakage mainly lie in three aspects: material selection, manufacturing process, and system matching. Firstly, some projects, in an effort to reduce costs, chose materials with poorer corrosion resistance, such as 201 or ordinary 304. These materials are prone to pitting and intergranular corrosion when exposed to cooling fluids containing ethylene glycol or deionized water for a long time, eventually leading to perforation leakage. Secondly, unstable welding quality is also a common problem. If the welds do not undergo solution treatment or are not inspected by flaw detection, cracks will occur after a certain period of operation. Thirdly, mismatched pipe sizes or excessive installation stress can also cause interface loosening and leakage during system operation.

In response to these issues, China Super Tech Co., Ltd. has provided targeted solutions. Our main products are 316 stainless steel liquid cooling tubes and 304 stainless steel liquid cooling tubes, which can cover various application scenarios. The 316 stainless steel liquid cooling tubes contain molybdenum, which has stronger resistance to pitting and crevice corrosion, and is suitable for use in coastal areas, high humidity environments, or cooling water containing high chloride ions; the 304 stainless steel liquid cooling tubes have excellent comprehensive performance and cost advantages in conventional data center environments, and can meet the long-term usage requirements of general cooling fluids. Both materials are produced in strict accordance with ASTM standards, with stable chemical composition and mechanical properties, ensuring the safety of the pipeline under high pressure, high temperature, and long-term operation conditions.

In the production process, we employ cold rolling forming and automatic welding techniques to ensure uniform pipe wall thickness and tight welds. All products undergo water pressure testing and eddy current inspection before leaving the factory to guarantee the absence of micro-cracks and pores. Through these measures, we have effectively reduced the leakage risk of the pipelines during use.

To meet the demands of the international market, we have also made adequate preparations in terms of inventory and delivery. The company currently has a large stock of stainless steel liquid cooling tubes, with a wide range of specifications available for immediate supply, ranging from 6mm to 219mm in diameter. Standard products can be shipped within the shortest possible time, shortening the procurement cycle for customers. At the same time, we also offer customized services, capable of producing non-standard sizes and wall thicknesses of pipe materials based on the drawings or technical requirements provided by customers, and providing corresponding pipe fittings and accessories to achieve one-stop purchasing.

In practical applications, our stainless steel liquid cooling pipes have been adopted by multiple overseas data center projects. Customer feedback indicates that after using our products, the operational stability of the liquid cooling system has significantly improved, the maintenance frequency has decreased, and the overall operating costs have been effectively controlled. This is attributed to our strict control over the quality of raw materials and the full-process monitoring of the production process.
