As global high-performance AIDC and large-scale data centers continue to upgrade towards high-density heat dissipation, long-cycle stable operation and high-standard clean liquid cooling, the inner wall precision and internal cleanliness of liquid cooling pipelines have become core factors that determine the operating efficiency, stability and service life of the entire liquid cooling system. As a subsidiary of YaoLong Group with 22 years of professional stainless steel piping R&D and precision manufacturing experience,  has built a full-process high-precision purification manufacturing system for CDU secondary-side annular loop piping, achieving industry-leading capabilities in precise inner wall roughness control and full-dimensional pipeline cleanliness optimization, and setting high-standard manufacturing benchmarks for AIDC liquid cooling piping products.

Different from ordinary industrial pipelines, AIDC liquid cooling CDU secondary-side annular loop piping poses extremely strict requirements on pipe inner wall smoothness. Unqualified roughness will easily cause coolant turbulence, flow resistance increase, particle adhesion and internal scaling, resulting in reduced heat dissipation efficiency and potential operational risks for server computing equipment. To solve the industry pain points, Yaolong Hygienic  adopts professional dedicated internal pipe polishing equipment for all liquid cooling piping products. Through standardized and refined precision polishing processes, the company realizes accurate and stable control of pipeline inner wall roughness, creating an ultra-smooth inner pipe surface. This core process effectively reduces coolant flow resistance, improves the overall circulation efficiency of the liquid cooling system, and fundamentally inhibits the adhesion of impurities, microorganisms and scale, fully meeting the 24/7 uninterrupted stable operation requirements of high-density computing data centers.

On the basis of high-precision polishing, Yaolong Hygienic further builds a full-automatic ultrasonic cleaning system to achieve full-coverage high-purity cleaning of CDU secondary-side annular loop piping and matching fittings. Abandoning the traditional manual cleaning method with unstable quality and dead cleaning zones, our intelligent ultrasonic cleaning production line realizes omnidirectional degreasing, decontamination and impurity removal for pipe inner walls, welding seams and structural dead corners. It thoroughly removes tiny welding slag, polishing dust, oil stains and residual impurities generated in the production and processing links, realizing zero residual pollution inside the pipeline. The standardized batch cleaning process ensures consistent high cleanliness of each product, satisfying the ultra-high cleanliness standards of super-large AIDC data center liquid cooling systems.

All core processing links including precision internal polishing and full-automatic ultrasonic cleaning are completed in Yaolong Hygienic ‘s independent 1,000㎡ Class 100,000 dust-free workshop. The strictly controlled dust-free closed manufacturing environment effectively isolates external dust and particulate pollution throughout the whole process of processing, cleaning and storage, avoiding secondary pollution of finished pipelines. Supported by TUV ISO9001 quality management system, US 3A certification and complete ISO welding quality and welder qualification certification, the company forms a closed-loop quality control system from raw material processing, precision polishing, intelligent cleaning to finished product inspection, ensuring every batch of CDU secondary-side annular loop piping maintains unified high precision, high cleanliness and high stability.

As the core terminal circulation carrier of data center liquid cooling systems, CDU secondary-side annular loop piping directly determines the uniformity of equipment heat dissipation and the stability of system circulation. Benefiting from precise roughness control technology, full-automatic ultrasonic purification process and dust-free intelligent manufacturing system, Yaolong Hygienic annular loop piping boasts outstanding advantages of low flow resistance, anti-scaling, high cleanliness and high durability. It perfectly solves common industry problems such as easy impurity accumulation, unqualified cleanliness and poor long-term stability of traditional liquid cooling pipelines, effectively improving the overall operation efficiency and long-term service life of AIDC liquid cooling systems.

Beyond superior product performance, Yaolong Hygienic relies on a professional R&D and technical team to provide one-stop customized solutions including piping scheme design, drawing deepening and engineering decomposition. The company can carry out personalized customization according to different data center layout and liquid cooling operation requirements, delivering high-cleanliness and high-precision CDU annular loop piping products for global customers. In the future, Yaolong Hygienic  will continue to focus on the technological iteration of high-purity liquid cooling piping, rely on sophisticated manufacturing strength to empower the high-quality development of global green and high-efficiency data centers, and provide reliable core piping support for the upgrading of liquid cooling infrastructure industry.
