Core Structure & Functionality
1. 360° Full-Range Observation
The innovative ring-shaped design offers a panoramic view, enabling uninterrupted monitoring from every vantage point. This ensures meticulous process control and aids in the prevention of potential mishaps, providing peace of mind and operational efficiency.
2. Material & Sealing
- Body: Meticulously constructed from premium corrosion-resistant stainless steel options (304, 316, 316L), each conforming to stringent food-grade standards. For unique applications, choose from optional carbon steel with fluoropolymer lining or fiberglass-reinforced plastic (FRP).
- Window: The sight glass is available in tempered borosilicate or quartz, delivering exceptional temperature resistance (borosilicate ranging from -10 to 250°C; quartz from -30 to 800°C).
- Seals: Enhanced with food-grade silicone rubber, PTFE, or NBR gaskets, guaranteeing superior leak-proof integrity and exceptional resistance to acids and alkalis.
3. Connection Types
Designed with versatility in mind, the sight glass is compatible with quick-install clamps (tri-clamp), flanges, threaded joints, or butt welding, allowing seamless integration with diverse pipeline systems. The swift-release design is ideal for applications demanding frequent maintenance or cleaning.
Technical Parameters
- Nominal Diameter (DN): DN15-DN150
- Pressure Rating: 0.6-2.5 MPa (catering to low-pressure needs in sanitary sectors and robust high-pressure requirements in chemical processes).
- Compatible Media: Versatile for a range of media including water, oil, steam, and various corrosive liquids/gases.
Key Advantages
1. Hygienic Design
Featuring electropolished surfaces with Ra ≤0.8μm, this design minimizes residue, adhering to GMP, 3A, and other essential sanitary certifications, ensuring cleanliness and safety.
2. Corrosion Resistance & Durability
The use of high-grade stainless steel combined with chemical-resistant seals offers unparalleled durability, even in the harshest environments.
3. Efficient Operation
The easy quick-install mechanism significantly reduces downtime during maintenance or cleaning, enhancing productivity and operational efficiency.
Applications
-Food & Beverage: Ideal for monitoring fluid flow in beer, dairy, or beverage production lines, providing clarity and control over production processes.
-Pharmaceutical & Chemical: Essential for observing intricate reactions in reactors or pipeline media, ensuring safety and precision.
-Petrochemical: Employed for critical safety inspections in oil and gas pipelines, safeguarding against leaks and ensuring compliance with safety standards.
Selection & Customization
To tailor the sight glass to your specific needs, please provide:
- The desired DN size, pressure rating, media type, and temperature range.
- Customization options include explosion-proof models, LED lighting for enhanced visibility in low-light environments, or specialized coatings for additional protection.
Precautions
- Installation: Ensure even force distribution during installation to prevent glass breakage. Tighten screws following a diagonal pattern for optimal stability.
- Maintenance: Conduct regular inspections of seals and glass, particularly in acidic or alkaline environments, to maintain optimal functionality and safety.
