Blind flanges are solid flanges without a bore that are specifically designed to seal the ends of pipelines, valves, or pressure vessels while maintaining optimum safety and reliability. They are widely employed in industries that demand frequent inspection, pressure testing, or flow isolation on a temporary basis. Blind flanges aid to avoid leakage, safeguard downstream equipment, and offer easy access for future system expansion or change without having to dismantle the entire pipeline.
Manufactured in a wide range of materials such as carbon steel, alloy steel, stainless steel, and duplex steel, blind flanges are suitable for both high-pressure and extreme temperature applications. Their robust construction ensures excellent resistance to mechanical stress, corrosion, and deformation over long service periods. Available in various pressure classes and international standards, blind flanges offer a dependable solution for critical piping systems across oil & gas, petrochemical, power, and process industries.
