Industrial-Grade Heavy-Duty Stainless Steel Flange for Chemical Applications

Product Description

Stainless Steel Sterile Flange

Product Description

Product Overview
Stainless Steel Sterile Flanges are expertly crafted connection components designed for hygienic fluid transfer systems where absolute cleanliness and microbial control are paramount. These indispensable components are a cornerstone in vital industries such as pharmaceuticals, biotechnology, food & beverage, dairy, cosmetics, and fine chemicals. They are crucial for ensuring Clean-in-Place (CIP) and Sterilize-in-Place (SIP) protocols are met. By facilitating smooth, crevice-free, and easily cleanable fluid pathways, these flanges preserve product purity and maintain the integrity of processes.


Key Features & Benefits
1. Hygienic Design
- Mirror-Polished Surfaces: The internal surfaces are meticulously polished to achieve ultra-low roughness (Ra ≤ 0.8 μm), effectively preventing microbial adhesion and residue buildup.
- Zero Dead-Leg Design: Flawless alignment with pipes and gaskets according to DIN 11866, ISO 2852, SMS 1145, RJ standards, eliminating stagnation zones and ensuring seamless fluid transfer.
- Integrated Gasket System: Incorporates sterile-grade gaskets, such as PTFE-encapsulated silicone or EPDM, ingeniously recessed into flange grooves to prevent product contact, ensuring optimal hygiene.

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

3. Reliable Sterile Sealing
- Tri-Clamp/SMS/RJT Connections: Quick-install clamps or threaded unions ensure a leak-proof seal, while allowing for rapid disassembly for thorough cleaning.
- Uniform Compression: Guarantees even gasket loading to prevent deformation, ensuring consistent performance of SIP/CIP processes.

4.CIP/SIP Compatibility
- Endures aggressive cleaning agents like acids and alkalis, as well as steam sterilization at high temperatures (≥121°C, 15+ PSI).
- Designed with smooth internal geometry to ensure full coverage by cleaning and sterilizing agents, maintaining cleanliness and sterility.

5. Global Standard Compliance
- Adheres to global standards including DIN 11866, ISO 2852, SMS 1145, 3-A Sanitary Standards, and EHEDG guidelines for universal applicability.
- Available in a range of sizes from DN 15-150 (½"-6") with multiple pressure ratings to suit various applications.


Typical Applications
- Pharma/Biotech: Ideal for fermenters, bioreactors, purification skids, and filling lines, ensuring sterile conditions.
- Food & Beverage: Perfect for dairy processing, juice and beer pipelines, and sauce transfer, maintaining product quality.
- Cosmetics: Supports emulsion, serum, and perfume manufacturing with precision and hygiene.
- Fine Chemicals: Facilitates the distribution of high-purity solvents with utmost reliability.


Summary
Stainless Steel Sterile Flanges provide unwavering hygienic performance for critical processes. Merging advanced metallurgy, dead-leg-free geometry, and standardized connections, these flanges significantly reduce contamination risks while enabling efficient maintenance. They are the optimal choice for systems where zero product retention and validated sterility are non-negotiable.
