What is a Blind Flange?
A Blind Flange is a solid disk used to block off a section of a pipe or a valve. Unlike other types of flanges, it has no bore and is primarily used to isolate sections of a pipeline or terminate a pipeline system. These flanges are commonly employed in high-pressure applications where a strong, durable seal is essential.
