Key Features & Benefits
1. Hygienic Design
- Revel in flawless cleanliness with our mirror-polished surfaces. Our internal surfaces boast an ultra-low roughness (Ra ≤ 0.8 μm), effectively preventing microbial adhesion and residue accumulation.
- Zero Dead-Leg Design: Expertly crafted to align seamlessly with pipes and gaskets (compliant with DIN 11866, ISO 2852, SMS 1145, RJ standards), these flanges eliminate stagnation zones, ensuring optimal flow and hygienic conditions.
- Integrated Gasket System: Featuring sterile-grade gaskets like PTFE-encapsulated silicone/EPDM, these are expertly recessed into flange grooves, maintaining aseptic conditions by preventing product contact.

2. Premium Material Construction
- Crafted from superior 316L/304L Stainless Steel, offering unmatched corrosion resistance and high-temperature tolerance (up to 250°C), all while complying with FDA/EC1935 safety standards for product contact.
- Electropolishing Option: Opt for this to enhance passivation, achieving maximum cleanliness and surface protection.

3. Reliable Sterile Sealing
- Select from Tri-Clamp/SMS/RJT connections for quick-install clamps or threaded unions, ensuring a leak-proof seal and enabling rapid disassembly for thorough cleaning.
- Uniform Compression: The design guarantees even gasket loading to prevent deformation, securing consistent SIP/CIP performance every time.

4.CIP/SIP Compatibility
- Engineered to withstand aggressive cleaning agents and steam sterilization processes (≥121°C, 15+ PSI), these flanges preserve their integrity throughout.
- Smooth internal geometry ensures comprehensive coverage by cleaning and sterilizing agents, facilitating thorough internal cleaning.

5. Global Standard Compliance
