Stainless Steel Sterile Flange

Product Overview
Stainless Steel Sterile Flanges are precision-engineered marvels, crafted to perfection for hygienic fluid transfer systems where absolute cleanliness and microbial control are paramount. Essential across pharmaceuticals, biotechnology, food & beverage, dairy, cosmetics, and fine chemicals industries, these flanges are indispensable where CIP (Clean-in-Place) and SIP (Sterilize-in-Place) protocols are non-negotiable. They promise fluid pathways that are smooth, crevice-free, and effortless to clean, ensuring the pinnacle of product purity and process integrity.


Key Features & Benefits
1. Hygienic Design
- Mirror-Polished Surfaces: Our internal surfaces are polished to an ultra-low roughness of Ra ≤ 0.8 μm, expertly preventing microbial adhesion and residue buildup.
- Zero Dead-Leg Design: Engineered for seamless alignment with established standards (DIN 11866, ISO 2852, SMS 1145, RJ), these flanges eradicate stagnation zones.
- Integrated Gasket System: Featuring sterile-grade gaskets, such as PTFE-encapsulated silicone/EPDM, recessed precisely into flange grooves, ensuring no product contact.

2. Premium Material Construction
- Grade 316L/304L Stainless Steel: Offering superior corrosion resistance and high-temperature tolerance (up to 250°C), fully compliant with FDA/EC1935 standards for safe product contact.
- Electropolishing Option: Provides enhanced passivation, delivering maximum cleanability.

3. Reliable Sterile Sealing
- Tri-Clamp/SMS/RJT Connections: These quick-install clamps or threaded unions offer leak-proof sealing while allowing swift disassembly for thorough cleaning.
- Uniform Compression: Even gasket loading ensures deformation-free sealing and consistent SIP/CIP performance.

4.CIP/SIP Compatibility
- Resilient against aggressive cleaning agents (acids/alkalis) and steam sterilization conditions (≥121°C, 15+ PSI).
- The smooth internal geometry guarantees comprehensive coverage by cleaning and sterilizing agents.

5. Global Standard Compliance
- Adheres to DIN 11866, ISO 2852, SMS 1145, 3-A Sanitary Standards, and EHEDG guidelines.
- Available in DN 15-150 (½"-6") sizes with multiple pressure ratings to suit diverse needs.


Typical Applications
- Pharma/Biotech: Perfect for fermenters, bioreactors, purification skids, and filling lines.
- Food & Beverage: Ideal for dairy processing, juice/beer pipelines, and sauce transfer systems.
- Cosmetics: Essential for emulsion, serum, and perfume manufacturing processes.
- Fine Chemicals: Optimal for high-purity solvent distribution.


Summary
Stainless Steel Sterile Flanges offer unparalleled hygienic performance for your most critical processes. With a blend of advanced metallurgy, dead-leg-free geometry, and standardized connections, these flanges significantly reduce contamination risks while ensuring efficient maintenance. They are the ideal choice for systems requiring zero product retention and validated sterility.
