Brand Introduction
Industrial operations face persistent challenges from particulate contamination, pressure fluctuations, and corrosion in high-pressure pipeline systems. Wuxi Yuanmei addresses these pain points through aerospace-grade materials and precision engineering, delivering carbon steel flange filters that withstand working pressures up to 4.0 MPa while maintaining filtration efficiency of 99.9%. Founded in January 2016 and headquartered in Wuxi, Jiangsu Province, the company holds 32 authorized patents and ISO 9001 certification, serving semiconductor, lithium battery, food & chemical, medical & pharmaceutical, and new energy industries across the Yangtze River Delta and global markets including India, Vietnam, and the United States.
Core Technology & Products
Wuxi Yuanmei's Carbon Steel Flange Filter integrates three technical modules:
High-Pressure Structural Design: Carbon steel construction with ANSI/PN flange connections engineered for heavy-duty applications. The precision-machined body resists corrosion and wear, with standardized flange interfaces ensuring secure, leak-proof installation. An integrated blow-down valve enables maintenance without system shutdown, reducing operational downtime.
Advanced Filtration Performance: The optimized internal flow channel design minimizes pressure drop while achieving efficient removal of solid contaminants from air, water, and oil media. Filtration precision ranges from 10-300 mesh (customizable), protecting downstream precision equipment from costly damage. Working pressure capacity spans 1.6-10 MPa, with temperature tolerance from -20℃ to 250℃.
Cost-Efficiency Engineering: Compared to stainless steel alternatives, the carbon steel construction delivers 30%-50% reduction in total procurement costs while maintaining comparable performance standards. The quick-access screen cleaning system and durable materials extend service life, lowering lifecycle maintenance expenses.
Industries Served
The company's filtration solutions serve multiple high-end sectors: semiconductor manufacturing (compressed air purification), lithium battery production (process fluid filtration), food & chemical processing (hygiene-compliant air treatment), medical & pharmaceutical facilities (sterile air systems), cosmetics manufacturing (contamination control), and new energy applications (system protection). Long-term partnerships with advanced manufacturing enterprises across the Yangtze River Delta validate the technology's reliability in critical production environments.
Case Studies & Quantifiable Results
