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 you choose your next sight glass, there are a variety of key specifications and glass material questions to answer, based on application temperature, how any chemicals used react to the glass, and the level of pressure involved. And, you’ll want to understand the differences between true borosilicate glass – its performance and certifications – compared to others that may be suggested as equivalent alternatives.
