Product Description
1. Product Overview
Sanitary stainless steel four-way/straight-through flange sight glasses are indispensable observation tools in industrial pipeline systems. They are extensively utilized across petrochemical, pharmaceutical, food, and chemical industries to provide real-time monitoring of liquid, gas, or vapor flow conditions, color variations, and chemical reactions. They boast essential features such as:
- Sanitary Design: Equipped with exquisitely mirror-polished surfaces (Ra ≤ 0.8μm), these sight glasses meet prestigious standards like **GMP, 3A, and IDF**, ensuring suitability for ultra-clean environments such as food production and pharmaceuticals.
- Corrosion Resistance: Crafted from top-quality materials like **SUS304, 316L, 2205 duplex steel**, with optional fluoropolymer-lined or FRP choices, these glasses are designed for hostile chemical environments.
- Structural Versatility: Available in four-way (360° observation) or straight-through formations, they are tailored for versatile installation needs.
2. Technical Specifications
1. Materials
- Body: Options include 304, 316L, 2205 duplex steel, and 904L stainless steel for optimal durability.
- Window: Choose between tempered borosilicate glass (withstanding ≤280°C) and quartz glass (enduring ≤1000°C), with pressure capabilities from 0.6 to 2.5 MPa.
- Seals: Featuring NBR, PTFE, or graphite gaskets, they are ideal for applications involving high temperatures.
2. Operating Conditions
- Temperature Range:
- Stainless steel body: Capable of enduring extreme conditions from -196°C to +600°C.

3. Dimensions & Standards
- Port Sizes: Available in DN20-DN200, with custom sizes crafted to order.
- Flange Standards: Compatible with HG, GB, ANSI, JIS, and DIN, adhering to **Chemical Industry Standards HGJ501-502-86**.
3. Core Structure & Features
1. Components
- Includes a sturdy base plate, viewing window, sealing gaskets, flanges, and fasteners.
- The four-way type offers comprehensive multi-angle observation, while the straight-through design is perfect for linear pipework.
2. Functional Advantages
- Leak-proof Sealing: RF and MFM flange faces ensure security in high-pressure settings.
- Thermal Shock Resistance: Withstands abrupt temperature shifts up to 60°C with ease.
- Easy Maintenance: Featuring a quick-disassembly design, these sight glasses minimize downtime and simplify upkeep.
4. Applications
- Chemical Industry: Essential for monitoring aggressive media such as acids and alkalis, helping prevent crystallization or blockages.
- Pharmaceutical & Food: Guarantees clarity and hygiene in sterile conditions for drug solutions or dairy product pipelines.
- Energy & Environmental: Ideal for tracking high-temperature steam, oils, or wastewater in various treatment systems.
5. Installation & Maintenance Guidelines
1. Installation
- Ensure glass purity by cleaning with alcohol wipes, strictly avoiding acidic cleansers.
- Secure bolts diagonally and evenly to safeguard against glass fracturing.
- Opt for graphite gaskets in high-temperature settings or PTFE for cryogenic environments.
2. Maintenance
- Conduct regular inspections of the glass for any signs of corrosion, with increased frequency in harsh environments.
- Replace glass only when sealing surfaces are intact to prevent leakage issues.
