Stainless Steel Sight Glass Manhole
Product Description
Product Overview
Introducing the Stainless Steel Sight Glass Manhole - a robust industrial marvel that seamlessly merges the dual functionalities of an observation window and maintenance access portal. Perfectly suited for sealed containers such as storage tanks, reactors, and pipelines, this manhole allows for real-time monitoring coupled with effortless maintenance access. Its standout features include:
- Dual Functionality: Effortlessly observe internal media conditions, including liquid levels, flow, and reactions, while providing convenient access for inspections.
- High Sealing Performance: Engineered with flanged or quick-opening structures to deliver exceptional safety in high-pressure, vacuum, and corrosive environments.
- Sanitary Design: Features mirror-polished surfaces (Ra ≤ 0.4μm) and is fully compliant with GMP, FDA, and EHEDG standards, making it ideal for high-cleanliness applications such as food and biopharmaceuticals.
Structural Features
1. Integrated Design:
- Ingeniously combines the sight window and manhole cover, significantly reducing leakage risks from additional openings.
- Offers a quick-opening hinge/clamp mechanism for swift access, with optional safety pressure relief devices for enhanced security.
2. Safety Enhancements:
- Optional explosion-proof sight glass, certified for ATEX/IECEx compliance, ensuring utmost safety under all conditions.
- Equipped with an internal anti-fall grille or guardrail to ensure personnel safety during entry.
3. Customizable Options:
- Fully compatible with lighting, cleaning nozzles, or steam sterilization ports, adaptable to CIP/SIP systems.
- Features windows with engraved scales or transparent rulers for precise liquid level and flow monitoring.
Applications:
- Chemical Storage Tanks: Ideal for monitoring corrosive liquids such as acids and alkalis, effectively preventing overflow or crystallization.
- Bioreactors: Enables observation of sterile fermentation processes while facilitating efficient sampling and maintenance.
- Food Processing Vessels: Guarantees hygienic visual management for dairy and beverages, ensuring HACCP compliance.
- Environmental Equipment: Provides insightful tracking of internal conditions in wastewater treatment or biogas tanks.
Installation & Maintenance
1. Installation Guidelines:
- Always clean sealing surfaces before installation to maintain integrity and ensure a perfect fit.
- Tighten bolts diagonally and evenly according to torque standards such as ASME PCC-1 for optimal performance.
- Conduct hot tightening in high-temperature environments to adequately counteract thermal expansion.
2. Maintenance Tips:
- Regularly inspect window clarity and replace gaskets every three months in corrosive environments to maintain optimal functionality.
- Clean windows with neutral detergents to avoid scratches or thermal shocks, ensuring long-lasting clarity.
