About Sight Glasses

A sight glass is used for looking inside a process vessel or pipeline. For many years the Chemical Processing and related industries had only one choice in selecting a sight glass; a single thickness or glass bolted between two flanges in either the form of a round flat piece of glass or tubular cylinder. Many of these types of sight glasses are still in use today.

Today's modern sight glass is much more sophisticated to provide maximum safety under high pressure and temperature operations and a wide thermal shock range. We think it must be also be capable of resisting blow out or rupture.
