In the non-ferrous metal manufacturing and mining industries, precise oxygen detection in pipelines during startup phases is critical for ensuring production safety and facilitating smooth line commissioning. A leading domestic non-ferrous mining enterprise faced significant challenges during new production line commissioning and routine operations. Complex pipeline media—including nitrogen and acetylene—coupled with acidic mist and alkaline corrosion environments, demanded stringent detection accuracy despite typical oxygen levels of just 0.1%. Conventional detection equipment proved inadequate due to insufficient precision, installation incompatibility, and susceptibility to failure in complex media. These issues became core obstacles to production startup. To overcome this industry-wide detection challenge, the company partnered with Yiyuntian Eranntex a specialist in industrial gas detection. Leveraging years of technical expertise and customized solution capabilities, Yiyuntian Eranntex developed a tailored flanged pipeline oxygen detection solution. This successfully addressed the company's detection pain points, establishing a robust technical defense for production safety.

　　4. Field Test Case Diagram

　　Tailored to enterprise operational conditions, Yiyuntian Eranntex customized solutions precisely match material, sensor, and installation requirements, providing a one-stop solution for all detection challenges. Fixed detection probes with stainless steel housings and dedicated gas chambers resist acids, alkalis, and corrosion, perfectly adapting to complex media environments to ensure long-term stable operation. Sensors are selected based on media characteristics: industrial-grade electrochemical sensors for pure nitrogen media, and fluorescent oxygen sensors for complex media. Both achieve ultra-high resolution of 0.01% VOL, accurately capturing normal oxygen content at 0.1% to provide reliable data for process control. Compatible with existing flange specifications, it features DN20 and DN25 RF-face half-flanges for direct installation without pipeline modifications. This reduces construction costs, shortens installation time, and meets urgent detection needs during startup phases.

　　The deployed MIC-500S-O2-A oxygen detection probe demonstrated outstanding performance in field testing and received high recognition from the enterprise. Following implementation, the enterprise achieved 24/7 real-time online monitoring of pipeline oxygen levels. Accurate and stable data eliminates safety hazards caused by abnormal oxygen concentrations at the source. Equipment operation eliminates the need for frequent manual inspections and maintenance, enhancing detection efficiency while reducing operational costs. The combination of corrosion-resistant materials and specialized sensors significantly extends equipment lifespan, saving on replacement and repair costs and ensuring smooth plant startup and stable daily production.

　　Yiyuntian Eranntex customized solution for non-ferrous mining not only fortifies production safety defenses for partner enterprises but also establishes a replicable practical model for pipeline oxygen detection in complex industrial conditions. As a high-tech enterprise in industrial gas detection, Yiyuntian Eranntex consistently prioritizes technological innovation, developing tailored detection solutions addressing industry-specific operational challenges. This successful implementation further validates the company's robust technical capabilities and professional service expertise.
