Applicatons

Deployed in oil & gas exploration tools (downhole cameras), refinery reactors, pipeline inspection systems, and offshore drilling platforms for real-time visual monitoring under extreme pressure-temperature conditions. Critical for subsea equipment visualization and corrosion-resistant containment in hydrocarbon processing.

Key Features

Fabricated from alkali-free borosilicate glass (Type 3.3), offering exceptional thermal shock resistance (ΔT >500°C) and hermetic sealing against aggressive fluids like H₂S and crude oil fractions. Maintains optical clarity despite exposure to hydrocarbon condensates.

Advantages Over Alternatives

Surpasses soda-lime glass in resisting alkali metal vapor attacks common in petrochemical environments. Outperforms fused silica in cost-effectiveness for large-scale deployment while matching its thermal stability. Eliminates fogging/clouding during rapid decompression cycles.

Benefits Gained

Enables safe operator oversight of hazardous processes → regulatory compliance; reduces unplanned maintenance via extended service life (5–7x vs. standard glass); supports predictive maintenance through clear process visualization; lowers total ownership cost via minimal replacement frequency.
