What is the difference between a spectacle blind and a blind flange?
The main difference lies in their functionality. A spectacle blind flange is designed for flow control and visual indication, allowing easy isolation of pipeline sections. On the other hand, a blind flange is used to permanently seal off the end of a pipeline or vessel without any openings.
What are applications of Spectacle blind flanges?
Spectacle blind flanges are commonly used for periodic maintenance, repairs, or modifications in pipelines, as well as for flow diversion, pressure relief, or visual indication purposes. Blind flanges are typically used to permanently close off the end of a pipeline or vessel during construction, testing, or when the section is not in use.
