Wenzhou Walmi Stainless Steel Flanges: Setting a New Benchmark in Industrial Safety with Precision Quality
In the field of industrial pipeline connections, stainless steel flanges are core components. Their material selection and manufacturing process are directly related to the stability and safety of system operation. Wenzhou Walmi Stainless Steel Co., Ltd., leveraging its 304/316L dual-material system and precision manufacturing technology, has become a trusted supplier for numerous companies. The following is an in-depth analysis of the outstanding value of Walmi Stainless Steel Flanges from three perspectives: product characteristics, process advantages, and industry applications.
Material Innovation: The Dual Protection of 304 and 316L
Walmi flanges utilize a 304/316L dual-material system to precisely meet diverse operating requirements. 304 stainless steel, with its golden ratio of 18% chromium and 8% nickel, provides basic corrosion resistance and economical performance, making it suitable for general chemical and food processing applications. 316L, with its 2% molybdenum addition, elevates chloride corrosion resistance to new heights, making it the preferred choice for demanding environments such as marine engineering, pharmaceutical equipment, and high-purity gas transportation. Both materials undergo solution treatment and electrolytic polishing, achieving an inner wall roughness of Ra ≤ 0.2μm. This ensures zero-residue fluid transfer and resists bacterial growth, complying with international standards such as GB/T 12771-2000 and ASTM A269.
Precision Manufacturing: Millimeter-Level Precision and a Sealing Revolution
Walmi Flange’s manufacturing process embodies its core strengths of “high precision and short lead times.” Using German CAD design software and material testing machines, Walmi achieves digital control throughout the entire design and production process. A roll bending line, precision cutting unit, and straightening unit work in tandem to ensure bolt hole distribution tolerances of ≤ 0.1mm and sealing surface flatness within 0.05mm. A multi-layer sealing structure combined with bright annealing ensures zero leakage even in high-pressure and high-temperature environments. Surface electrolytic polishing creates a passivation protective layer, extending service life by over 30%. With an annual production capacity of 25,000 tons, Walmi Flange supports custom lengths from 2 to 6 meters, meeting the ultra-large size requirements of new energy storage and nuclear power equipment. Industry Certifications and Quality Assurance
Walmi products comply with ISO 9001 quality management system requirements and strictly adhere to international standards such as JIS and DIN. Its 304/316L materials are verified by spectral analysis to ensure precise control of nickel, chromium, and molybdenum content. In customer applications, Walmi flanges have been successfully used in BYD, CATL’s new energy storage projects, and the Zhejiang San’ao Nuclear Power Project. With a 99% yield rate and a 15% material savings rate, Walmi has helped customers reduce production costs by 25%, making it a reliable partner for these “hidden champions” in their respective segments.
Upgraded Service: Full-Lifecycle Support from Customization to After-Sales
Walmi offers one-on-one customization services, supporting compliance with multiple standards including national, American, and Japanese standards. A professional team provides on-site installation guidance and sealing performance testing. Expedited orders are completed within three days. Each flange undergoes chemical solvent cleaning, ultrasonic pure water cleaning, and nitrogen purging. Each flange is packaged in double-layer anti-static bags and final packaging is completed in an ISO Class 4 cleanroom to ensure contamination-free transportation. Conclusion
Wenzhou Walmi Stainless Steel Co., Ltd., guided by the philosophy of “Simplicity and Honesty for Fine Steel,” is redefining the industry standard for stainless steel flanges through its 304/316L dual-material system, millimeter-level precision manufacturing, and comprehensive quality control.
