Metal fused sight glasses

METAGLAS® Sight Glass Windows

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.
