High Temperature Resistant Tempered Glass Gauge Glass for Boiler Water Level Indicator & Pressure Vessel


1. Core Material & Manufacturing:

  • Base Material: High-quality, optically clear soda-lime glass or borosilicate glass.

  • Key Process: Precision-cut glass that undergoes thermal tempering and often chemical strengthening to create tempered gauge glass.


2. Defining Physical & Performance Properties:

  • Extreme Temperature & Pressure Resistance: Specifically engineered to withstand the high internal temperatures (up to 300°C+) and pressures of steam boilers and vessels without failing.

  • Thermal Shock Resilience: Withstands rapid temperature fluctuations between steam/water phases and ambient conditions without cracking.

  • High Mechanical Strength: Tempering provides superior resistance to vibration, mechanical stress, and hydraulic pressure compared to ordinary glass.

  • Chemical Durability: Resistant to corrosion and etching from hot water, steam, and common boiler water treatment chemicals to maintain long-term clarity.

  • Safety Feature: Designed to contain failure, often fragmenting into less hazardous granular pieces if critically overstressed.


3. Primary Function in a System:

  • Critical Visual Monitoring Component: Serves as the transparent window in a water level gauge or sight glass, allowing for direct, real-time visual inspection of liquid levels inside a sealed vessel.

  • Safety & Process Control: Enables operators to safely monitor boiler water levels to prevent dangerous dry-firing or overfilling, which is vital for operational safety and efficiency.

  • Pressure Boundary: Forms an integral part of the pressure-containing assembly, maintaining a leak-proof seal under demanding conditions.


4. Target Applications & Industries:

  • Steam Boilers & Generators: For fire-tube, water-tube, and electric boilers in industrial plants, laundries, and hospitals.

  • Industrial Pressure Vessels: Reactors, autoclaves, condensers, and tanks requiring level sighting.

  • Power Generation: In fossil fuel and biomass power stations for boiler drum level indication.

  • Marine & Locomotive: For steam boilers on ships and heritage steam engines.

  • Heating Systems: In large commercial and institutional heating systems.
