L.J. Star (www.ljstar.com), a manufacturer of process observation equipment, is offering an online engineering tutorial on sightglass technology for chemical and pharmaceutical processing applications.

The free webinar begins with an overview of the essential aspects of glass, noting the various formulations used in chemical, food, and pharmaceutical process observation equipment. The tutorial focuses on sightglass selection, installation, and proper maintenance, with explanations on how to safely and effectively use sightglasses in standard lines, as well as those where high temperature, high pressure, and sanitary requirements.

The tutorial also attempts to explain the technology behind prestressed borosilicate sightglasses. It explains how these metal/glass discs are manufactured and how the compressive force on the glass element changes its nature and capabilities.
