If you still have out of date soda lime sight glasses in your facility that haven’t been replaced with borosilicate glass, then the answer is no. Inferior quality glass tends to shatter or even explode under high pressure which can threaten your safety.
L.J. Star has extended its MetaClamp and METAGLAS sight glass window technology with new LED lighting technology that is said to provide the industry’s strongest and most compact solution available for viewing inside tanks and vessels.
Metaglas from L. J. Star is a fused sight glass said to be proven in thousands of installations around the world. Unlike some other sight glasses, the company says, it uses borosilicate glass, rather than less durable similar glass material that doesn’t carry the same level of safety and performance certifications for extreme temperatures and pressures.
Since it was developed in the 1970s, Metaglas has been known as the safest sight glass in the world. A number of chemical and manufacturing companies collaborated to create Metaglas, and to establish the standard with which it complies and by which all other sight glass is measured, a standard now called DIN7079.
