This DIN11851 welding union is a 304 stainless steel sanitary fitting designed for hygienic piping systems. Built to a DN40 nominal size, it features a compact 41 mm profile and a DN thread union assembly for versatile use in clean industry applications. The combination of DIN11851 compliance, welding union ends, and robust stainless steel construction delivers reliable, leaktight connections suitable for demanding environments. Key benefits Hygienic, sanitary design aligned with DIN11851 standards for food, beverage, and pharmaceutical processes. Corrosionresistant 304 stainless steel provides longterm durability in cleaninplace (CIP) and sterile environments. DN40 nominal size with a compact 41 mm profile supports spaceconstrained installations. Welding union ends paired with a DN thread union assembly enable secure, leaktight connections and straightforward integration with compatible components. Smooth, easytoclean surfaces help minimize contamination risk and improve process hygiene. Key attributes Material: 304 stainless steel Standard: DIN11851 End connections: welding union ends; DN thread union assembly Nominal diameter: DN40 Dimension reference: 41 mm Assembly type: DN thread union integration with welding union Compatibility and suitability Designed to mate with standard DIN11851 sanitary components and DN thread connections. Ideal for systems requiring a sanitary weld connection on a DN40 line, with compatible thread union options for easy component integration. Suitable for applications across food, beverage, and pharmaceutical industries that demand cleanability and corrosion resistance. Applications Dairy processing lines for milk transfer and CIP sequences, where sanitary fitments and robust welding connections are essential. Beverage production pipelines (water, juice, beer) requiring cleanability and reliable joint integrity in a hygienic system. Pharmaceutical manufacturing piping where DIN11851compliant fittings and 304 stainless steel construction support clean standards and contamination control. Notes For proper installation, ensure compatibility with existing DIN11851 components and observe appropriate welding procedures for the ends specified by the DIN11851 standard. Maintain clean surfaces during assembly to preserve hygienic performance and reduce contamination risks.
