METAGLAS® Sight Glasses

Metal fused sight glasses "METAGLAS®" consist of a sight glass that is fused into a steel ring.
The different expansion coefficients of glass and metal cause a compressive stress inside
the glass. The mechanical prestress commands a higher security compared to thermal
prestressed glasses. Because of the mechanical treatment of the steel ring, various
constructive soultions can be realised.
