Hygienic Stainless Steel Flanges for Food and Pharmaceutical Industries
Hygienic stainless steel flanges are specially designed components used in piping systems where cleanliness, sterility, and corrosion resistance are critical-especially in the food, beverage, pharmaceutical, biotech, and dairy industries.
🔹 Key Features of Hygienic Flanges:
| Feature | Description |
|---|---|
| Material | Typically made from 304, 304L, 316, or 316L stainless steel for excellent corrosion resistance and easy cleaning. |
| Surface Finish | Smooth, polished, or electropolished surfaces (Ra ≤ 0.8 µm or better) to prevent bacterial adhesion. |
| Design | Crevice-free, with clean-in-place (CIP) and sterilize-in-place (SIP) compatibility. No dead spaces where residue or microbes can accumulate. |
| Connections | Often connected via Tri-Clamp / Tri-Clover, DIN 11851, or SMS union systems for easy assembly/disassembly. |
| Compliance | Manufactured in accordance with standards like 3-A, FDA, EHEDG, and ASME BPE for sanitary applications. |
🔹 Common Types of Hygienic Flanges:
Tri-Clamp (Tri-Clover) Flanges – Quick-connect system, ideal for frequent cleaning.
DIN 11853 / DIN 11864 Flanges – Metric-based hygienic flanges used in European process systems.
SMS and ISO Flanges – Common in dairy and beverage industries.
ASME BPE Flanges – Designed specifically for bioprocessing equipment.
