Chilean EPC Giant CBSK Visits INOCO for Equipment Inspection, Writing a New Chapter in China-Chile Water Treatment Cooperation!
In June 2025, Chilean EPC leader CBSK and its Aguas Esperanza project team successfully inspected and accepted INOCO's high-pressure seawater automatic backwash filters. The equipment, featuring 3.5MPa high-pressure design, super duplex steel construction, and fully automated operation, earned high praise from the client. It will serve the 143.2km SIAM II seawater transmission system in South America, marking a technological breakthrough for China's high-end equipment manufacturing in overseas mega-infrastructure projects.
[Technological Breakthrough: 35-Year Durability Meets Extreme Environmental Challenges]
INOCO's delivered equipment demonstrates three core competitive advantages:
• Material Revolution: Utilizing super duplex steel S240 S32750 for both casing and internals, offering 40% better chloride corrosion resistance than conventional materials, ensuring zero major maintenance during its 35-year design life;
• High-Pressure Adaptation: The 3.5MPa pressure rating exceeds industry standards, withstanding system pressure fluctuations during coastal typhoons and storm surges;
• Smart Maintenance: In the unmanned Muelle Centinela area, the equipment automatically initiates backwash via pressure differential sensing, requiring no manual intervention - improving operational efficiency by 60% and perfectly solving traditional filters' maintenance challenges in harsh environments.
[Full-Chain Recognition: International Endorsement from Production Capability to Technical Standards]
After comprehensive inspection, CBSK's delegation affirmed at the technical review meeting:
• Production Scale: 50,000㎡ modern facility with 8 automated production lines ensures batch delivery capability for the 143.2km pipeline system;
• R&D Credentials: National Class-A design certification and high-pressure fluid equipment patent portfolio guarantee compliance with South American EN 13445 industrial standards;
• Quality Control: 12-step quality process from material spectrometry to hydrostatic burst testing, certified by ISO 9001 and ASME U, with all hydrostatic tests passed in one attempt.
Both parties have signed an MOU for future cooperation in Chilean desalination and industrial wastewater treatment projects.
[Industry Significance: Chinese Equipment Sets New Paradigm for Global Coastal Infrastructure]
This project marks INOCO's latest milestone in South America following successes in Southeast Asia and the Middle East. Industry analysts note it breaks Western monopolies in high-pressure seawater treatment technology, with its integrated "material-pressure-intelligence" solution providing replicable Chinese expertise for coastal infrastructure in 120+ countries. From Chile's Region II coastline to the 143.2km pipeline, INOCO's technological exports advance green Belt and Road infrastructure cooperation, contributing to transnational water.
