Product Description
1. Comprehensive Product Overview
Our sanitary stainless steel four-way or straight-through flange sight glasses serve as indispensable visual monitoring tools in industrial pipeline systems. They play a pivotal role across petrochemical, pharmaceutical, food, and chemical sectors, enabling real-time surveillance of liquid, gas, or vapor flow, color transitions, and dynamic reactions. Key attributes include:
- Sanitary Design: Boasting mirror-polished surfaces (Ra ≤ 0.8μm) that meet the stringent **GMP, 3A, and IDF standards**, these sight glasses are designed for high-cleanliness settings such as food production and pharmaceutical applications.
- Impressive Corrosion Resistance: Crafted from premium **SUS304, 316L, 2205 duplex steel**, with options for fluoropolymer linings or FRP materials, these sight glasses withstand challenging chemical environments.
- Structural Versatility: Offered in four-way (360° observation) or straight-through designs, they provide adaptability for various installation requirements.

- Energy & Environmental: Observes high-temperature steam, oils, or wastewater in treatment systems, ensuring optimal performance.
5. Installation & Maintenance Best Practices
1. Professional Installation
- Clean glass meticulously with alcohol wipes, avoiding acidic cleaners to maintain clarity and integrity.
- Bolts should be tightened diagonally and evenly to prevent stress-induced glass cracking.
- Employ graphite gaskets for high-temperature or PTFE gaskets for cryogenic environments to ensure optimal performance.
2. Proactive Maintenance
- Conduct regular inspections for signs of glass corrosion, increasing frequency in harsh conditions.
- Ensure glass replacement features intact sealing surfaces to prevent leaks and maintain system efficiency.
