What Is a Blind Flange?
A blind flange is more than just a component; it is a critical part of industrial piping systems designed to ensure safety, efficiency, and durability. Blind flanges are used to seal the end of a piping system or pressure vessel openings. They are commonly used for testing the flow of gas or liquid through a pipe or vessel. They also allow for easy access to the pipe in case work must be done inside the line.
Widely used in high-pressure environments, it plays a vital role in oil & gas, chemical, power, and water treatment industries for isolation, inspection, and pressure testing purposes.
Pro Tip: Blind Flanges are often designed to work seamlessly with Welding Neck Flanges in critical piping applications to ensure maximum system integrity.
