Product Overview
Stainless Steel Sterile Flanges are precision-engineered connection components designed for hygienic fluid transfer systemsrequiring absolute cleanliness and microbial control. They are essential in industries such as pharmaceuticals, biotechnology, food & beverage, dairy, cosmetics, and fine chemicals, where CIP (Clean-in-Place) and SIP (Sterilize-in-Place) protocols are critical. These flanges ensure smooth, crevice-free, and easily cleanable fluid pathways to maintain product purity and process integrity.
Key Features & Benefits
1. Hygienic Design
- Mirror-Polished Surfaces: Internal surfaces polished to ultra-low roughness (Ra ≤ 0.8 μm) to prevent microbial adhesion and residue buildup.
- Zero Dead-Leg Design: Seamless alignment with pipes/gaskets (per DIN 11866, ISO 2852, SMS 1145, RJ standards) eliminates stagnation zones.
- Integrated Gasket System: Sterile-grade gaskets (e.g., PTFE-encapsulated silicone/EPDM) recessed into flange grooves to avoid product contact.
2. Premium Material Construction
- Grade 316L/304L Stainless Steel: Superior corrosion resistance, high-temperature tolerance (up to 250°C), and compliance with FDA/EC1935 for product contact.
- Electropolishing Option: Enhanced passivation for maximum cleanability.
3. Reliable Sterile Sealing
- Tri-Clamp/SMS/RJT Connections: Quick-install clamps or threaded unions enable leak-proof sealing while permitting rapid disassembly for cleaning.
- Uniform Compression: Even gasket loading prevents deformation and ensures consistent SIP/CIP performance.
4.CIP/SIP Compatibility
- Withstands aggressive cleaning agents (acids/alkalis) and steam sterilization (≥121°C, 15+ PSI).
- Smooth internal geometry ensures full coverage by cleaning/sterilizing agents.
5. Global Standard Compliance
- Conforms to DIN 11866, ISO 2852, SMS 1145, 3-A Sanitary Standards, and EHEDG guidelines.
- Available in DN 15-150 (½"-6") sizes and multiple pressure ratings.
Typical Applications
- Pharma/Biotech: Fermenters, bioreactors, purification skids, filling lines.
- Food & Beverage: Dairy processing, juice/beer pipelines, sauce transfer.
- Cosmetics: Emulsion, serum, and perfume manufacturing.
- Fine Chemicals: High-purity solvent distribution.
Summary
Stainless Steel Sterile Flanges deliver uncompromising hygienic performance for critical processes. By combining advanced metallurgy, dead-leg-free geometry, and standardized connections, they mitigate contamination risks while enabling efficient maintenance. Ideal for systems demanding zero product retention and validated sterility.
