Tempered Borosilicate Level Gauge Sight Glass for High-Temp Industrial Tanks

Tempered Borosilicate Level Gauge Sight Glass for High-Temp Industrial Tanks

Material Composition

• Primary Material: Borosilicate glass (commonly Borosilicate 3.3 per ISO 3585 standards).

• Tempering Process: Chemically or thermally strengthened to enhance durability.

• Key Additives: Silicon dioxide (80-85%), boron trioxide (10-13%), and trace alkaline earth metals.

Key Properties

1. Thermal Resistance: Withstands temperatures up to 450°C (842°F) and thermal shocks from ΔT 160–200°C.

2. Mechanical Strength: Tempering increases impact resistance (4–5x stronger than annealed glass).

3. Chemical Durability: Resists corrosion from acids, alkalis, and solvents (pH 0–14).

4. Optical Clarity: Maintains transparency under extreme conditions for accurate visual monitoring.

Primary Function

• Level Monitoring: Provides a clear visual interface to inspect liquid/gas levels in high-temperature industrial tanks.

• Pressure Tolerance: Operates safely in systems with pressures up to 10–15 bar (varies by thickness).

• Safety Barrier: Acts as a leak-proof window, isolating internal tank conditions from external environments.

Applications

1. Chemical Processing Tanks: For aggressive acids, molten salts, or hot solvents.

2. Power Generation: Boilers, steam systems, and thermal oil reservoirs.

3. Oil & Gas: Refinery storage tanks, high-temp reactors, and LNG processing.

4. Pharmaceuticals: Sterilization autoclaves and reactors requiring hygienic visibility.

Advantages Over Alternatives

• Longevity: Outlasts soda-lime glass or polycarbonate in cyclic thermal environments.

• Safety: Tempered design minimizes fragmentation risks if damaged.

• Low Maintenance: Resists clouding, scaling, or chemical etching.

Industry Standards

• Complies with ASTM E438, ISO 3585, and DIN 7080 for high-temp applications.
