Stainless Steel Sight Glass Manhole
Product Description
Product Overview
Introducing the stainless steel sight glass manhole, a state-of-the-art industrial component skillfully engineered to serve dual purposes: it integrates an observation window with maintenance access, crafted specifically for sealed containers like storage tanks, reactors, and pipelines. This innovation ensures seamless real-time monitoring while facilitating easy personnel access for maintenance. Key features include:
- Dual Functionality: Meticulously observes internal media conditions such as liquid levels, flow dynamics, and reactions, providing effortless entry for inspection duties.
- High Sealing Performance: Features robust flanged or quick-opening structures that guarantee complete safety even under high-pressure, vacuum, and corrosive environments.
- Sanitary Design: Showcases mirror-polished surfaces (Ra ≤ 0.4μm), meeting rigorous GMP, FDA, and EHEDG standards, making it ideal for applications demanding high cleanliness such as in food and biopharmaceuticals.
Structural Features
1. Integrated Design:
- Ingeniously combines the sight window with the manhole cover, significantly reducing leakage risks from extra openings.
- Equipped with a quick-opening hinge/clamp mechanism for rapid access, with optional safety pressure relief devices for enhanced security.
2. Safety Enhancements:
- Designed with optional explosion-proof sight glass, thoroughly certified for ATEX/IECEx compliance, ensuring maximum safety.
- Comes with internal anti-fall grille or guardrail to ensure personnel safety during entry.
3. Customizable Options:
- Perfectly compatible with lighting, cleaning nozzles, or steam sterilization ports, seamlessly integrating with CIP/SIP systems.
- Features windows with engraved scales or transparent rulers for precise liquid level and flow monitoring.
Applications:
- Chemical Storage Tanks: Expertly monitors corrosive liquids like acids and alkalis, preventing overflow or crystallization.
- Bioreactors: Diligently observes sterile fermentation processes, facilitating easy sampling and maintenance.
- Food Processing Vessels: Maintains stringent hygienic visual management for dairy and beverages, ensuring HACCP compliance.
- Environmental Equipment: Efficiently tracks internal conditions within wastewater treatment or biogas tanks.
Installation & Maintenance
1. Installation Guidelines:
- Thoroughly clean sealing surfaces before installation to maintain integrity.
- Secure bolts diagonally and evenly following torque standards, such as ASME PCC-1.
- Execute hot tightening in high-temperature environments to effectively counteract thermal expansion.
2. Maintenance Tips:
- Regularly inspect window clarity and replace gaskets every three months in corrosive environments to ensure durability.
- Clean windows with neutral detergents and avoid scratches or thermal shocks to preserve quality.
