Introduction
Conventional sight glasses are sensitive to stress, bending and impact and when subject to mechanical overload they may catastrophically fail without warning. This can cause a relatively minor expense and
inconvenience if it happens during installation but a major cost and safety implication if it occurs when plant is fully operational. METAGLAS® eliminates this mode of sight glass failure, helping to improve safety and avoid the expense and inconvenience of unscheduled plant shut downs. These advantages are due to the unique „glass fused to metal“ fabrication of METAGLAS® which gives it unmatched strength and integrity. METAGLAS® is made by melting circular glass inside a metal frame. This results in the fusion of glass and metal. Upon cooling, the glass solidifies and the difference in the linear coefficient of thermal expansion between glass and metal then produces forces that create a uniform compressive stress throughout the glass. This high degree of mechanically induced compressive stress makes METAGLAS® the strongest and most secure sightglass for sight window or visual flow indicator application.
Special Features
ETAGLAS® can replace conventional glass in many applications including circular flange assemblies for welding into vessels, weld neck & nozzle flanges and sight flow indicators. In addition, Metaglas cover flanges can be mounted onto flat face base flanges, these are available for all international flange connections including ANSI & BS. Existing installations can therefore be easly retrofitted to improve safety and extend plant life. The unique properties of METAGLAS® also make it ideal for use with sanitary mounting systems. METACLAMP®s are available as sight glass caps for sanitary clamp and In-line systems and sight glasses and Luminaire adaptors for sterile flush mount designs such as the NA-Connect system and Triclamp fittings. METAGLAS® has been subjected to the most rigorous tests by specific testing facilities in the chemical industry and has subsequently been integrated into their works standards.

Special Features
- Reliability against total failure – due to the mechanically prestressed glass
- Unurpassed resistance to prssure, impact and temperature
- Simple, stress free installation – resistant to bending, overtightening and impact
- Reusable – Metaglas can be cleaned and reused in the same or other applications, conventional sight
- glasses cannot
