A white paper offers a guide to glass selection to avoid sight-glass failure. The paper also offers advice about the conditions that must be considered during the design phase of a process application.
Free from L.J. Star Inc., Twinsburg, Ohio, “6 Tips for Critical
Sight Glass Applications” explains how and why sight-glass failures can occur from
temperature, thermal shock, pressure, caustics, abrasion or impact.
The highly engineered products are essential for the inspection
and maintenance of vessels and pipelines in food, beverage, chemical and pharmaceutical
processing plants. However, extreme forces, whether internal or external, can harm
visibility and strength of glass components in a process vessel. Minor cracks, scratches
or abrasions of the glass create weakness within the glass, increasing the likelihood
of failure. When a sight glass fails, it can be dangerous, deadly and potentially
catastrophic. In addition, the failure can result in downtime, scrapping the process
media and bringing on EPA or OSHA inspections.
