How to select the right sight glasses with the correct specs

Improperly specified, installed or maintained sight glasses can represent the weakest link in a processing system. The wrong glass or materials used will limit observation, require extra maintenance and replacements, and even fail under pressure with catastrophic results – since glass can fracture at 5 miles/second.

Before a company chooses its next sight glass, there are a variety of key specifications and glass material questions to answer, based on design temperature, chemical corrosion, and pressure rating. ​

And, there are differences to understand between true borosilicate glass – its performance and certifications – compared to others that may be suggested as equivalent alternatives.
