Look Better: Overcoming Challenges and Best Practices for Sight Glass Selection, Inspection, and Maintenance

Improperly specified, installed or maintained, sight glasses can quickly become the weakest link in a processing system. As a result, they may provide less-than-needed observation capabilities, require frequent maintenance and replacement, be difficult to illuminate, and, in the worst case, fail, endangering workers and causing extensive destruction and downtime.

Failure is an entirely preventable circumstance. An understanding of the nature of the various types of glass, the different sight glass design options and construction materials, and proper maintenance procedures will provide process observation and illumination that will serve and survive through the system’s life.
