Sanitary Stainless Steel Hex Flange Sight Glass
Product Description
Product Overview
Expertly crafted for the most demanding high-purity sectors, including food processing, pharmaceuticals, and biotechnology, our sanitary stainless steel hex flange sight glass offers unparalleled real-time visual monitoring of fluid dynamics, liquid levels, and reaction processes within both pipelines and vessels. With its hygienically designed stainless steel construction, paired with a pressure-resistant, high-transparency viewing window and a secure hex flange sealing mechanism, this innovative product excels in functionality and cleanliness, fully adhering to the strict standards needed for sterile production environments.
Key Features
1. Material & Hygiene Certifications
- Fabricated from robust SUS 304/316L stainless steel, our sight glass meets FDA, EHEDG, and 3-A Sanitary Standards. The surface is mirror-polished (Ra ≤0.6μm) or electropolished, effectively inhibiting microbial growth.
- The window is crafted from either high-grade tempered borosilicate glass or quartz glass, ensuring exceptional transparency and impact resistance. It withstands up to 200°C and is ISO 4802 certified for food-safe glass applications.
2. Hygienic Structural Design
- Our hex flange connection features a compact design with internal hex bolts, providing robust fastening. The flat sealing surfaces, combined with silicone/EPDM/PTFE gaskets, guarantee zero leakage and smooth disassembly for cleaning.
- Designed to be dead space-free, the sight glass is flush-mounted with pipeline walls, eliminating crevices where residues might accumulate. It is fully compatible with CIP/SIP cleaning and sterilization processes.
3. Performance Specifications
- Pressure Resistance: Built to withstand pressures from -0.1 to 1.0 MPa, with an option to customize up to 1.6 MPa for specialized high-pressure scenarios.
- Temperature Range: Efficiently operates between -20°C and +150°C, with short-term window tolerance extending up to +250°C.
- Media Compatibility: Versatile in use, suitable for handling water, steam, acidic or alkaline solutions, dairy products, pharmaceuticals, and beyond. For corrosive fluids, 316L stainless steel is recommended.
