Stainless Steel Sterile Flange
Product Description
Product Overview
Stainless Steel Sterile Flanges are expertly crafted connection components, purpose-built for hygienic fluid transfer systems where absolute cleanliness and microbial control are non-negotiable. These essential components serve a pivotal role in industries such as pharmaceuticals, biotechnology, food & beverage, dairy, cosmetics, and fine chemicals, where the utmost standards of CIP (Clean-in-Place) and SIP (Sterilize-in-Place) protocols are upheld. Designed to perfection, these flanges ensure fluid pathways that are smooth, crevice-free, and effortlessly cleanable, thereby preserving product purity and process integrity.
Key Features & Benefits
1. Hygienic Design
- Mirror-Polished Surfaces: The internal surfaces are polished to an ultra-low roughness (Ra ≤ 0.8 μm), effectively preventing microbial adhesion and residue buildup.
- Zero Dead-Leg Design: These flanges seamlessly align with pipes and gaskets following DIN 11866, ISO 2852, SMS 1145, and RJ standards, eliminating stagnation zones.
- Integrated Gasket System: Sterile-grade gaskets, such as PTFE-encapsulated silicone or EPDM, are recessed into flange grooves to avoid direct product contact.
2. Premium Material Construction
- Grade 316L/304L Stainless Steel: Offers superior corrosion resistance, high-temperature tolerance (up to 250°C), and complies with FDA/EC1935 standards for product contact.
- Electropolishing Option: Provides enhanced passivation, ensuring maximum cleanability.
3. Reliable Sterile Sealing
- Tri-Clamp/SMS/RJT Connections: Quick-install clamps or threaded unions provide leak-proof sealing while allowing rapid disassembly for cleaning.
- Uniform Compression: Even gasket loading prevents deformation, ensuring consistent SIP/CIP performance.
4.CIP/SIP Compatibility
- Capable of withstanding aggressive cleaning agents, both acidic and alkaline, as well as steam sterilization at temperatures ≥121°C and pressures of 15+ PSI.
- Smooth internal geometry guarantees full coverage by cleaning and sterilizing agents.
5. Global Standard Compliance
- Conforms to DIN 11866, ISO 2852, SMS 1145, 3-A Sanitary Standards, and EHEDG guidelines.
- Available in sizes ranging from DN 15-150 (½"-6") and comes in multiple pressure ratings to suit diverse applications.
Typical Applications
- Pharma/Biotech: Applied in fermenters, bioreactors, purification skids, and filling lines.
- Food & Beverage: Utilized in dairy processing, juice/beer pipelines, and sauce transfer systems.
- Cosmetics: Essential for manufacturing emulsions, serums, and perfumes.
- Fine Chemicals: Perfect for high-purity solvent distribution.
Summary
Stainless Steel Sterile Flanges offer unbeatable hygienic performance for critical processes. By merging advanced metallurgy, dead-leg-free geometry, and standardized connections, they successfully mitigate contamination risks while ensuring efficient maintenance. They are the ideal choice for systems that demand zero product retention and validated sterility.
