Stainless Steel Blind Flange is a hygiene-focused sealing component engineered for cleanroom environments and sanitary piping systems. Crafted from food-grade 316L stainless steel with a high-polish finish (Ra ≤ 0.8μm), it eliminates crevices and rough surfaces that harbor contaminants, making it perfect for food & beverage processing, pharmaceutical manufacturing, biotech labs, and cosmetic production facilities.
Its core advantages lie in sanitary design and easy sterilization. The seamless forged structure and electropolished surface comply with FDA, GMP, and 3-A Sanitary Standards, ensuring no cross-contamination of media. It supports frequent CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes, with a leak-tight seal that maintains the sterility of closed piping systems, while the smooth finish simplifies cleaning and reduces maintenance downtime.
Compliant with ASME B16.5, 3-A Sanitary Standards, and DIN 11851, our blind flanges cover sizes from 1/2" to 24" for small-batch labs and large-scale production lines. Each unit undergoes hygiene testing and surface roughness verification, with material certificates confirming food-grade compliance. The compatible sanitary gaskets (EPDM, silicone) ensure no toxic leaching, matching the strict requirements of clean industries.
As a sanitary flange specialist, we focus on contamination-free design and precision polishing. Our team provides tailored solutions—including custom polish levels and gasket matching for specific hygiene needs—and offers guidance on CIP/SIP integration. We also supply sterile packaging to maintain product cleanliness before installation in cleanroom environments.
For food, pharmaceutical, and cleanroom piping systems requiring uncompromising hygiene and sterility, our Stainless Steel Blind Flange is the ideal choice. Partner with us for sanitary-grade flanges that meet global hygiene regulations and ensure product safety.
