Mô tả Sản phẩmProduct OverviewBlind Flange, also known as Blank Flange, is a disc-shaped piping component designed to seal the end of a pipeline, valve, or equipment nozzle. It serves as a removable, leak-tight closure to isolate or terminate a piping system, facilitating maintenance, inspection, and future expansion of industrial pipelines. Manufactured with a solid, flat disc structure and bolt holes matching corresponding flanges, it is installed by bolting to the mating flange with a gasket in between. Compliant with global standards such as ASME, EN, GOST, and JIS, our blind flanges are engineered for reliability in various operating conditions, from low-pressure ambient systems to high-pressure, high-temperature industrial environments.Product FeaturesProduct AdvantagesProduct ApplicationsSuperior Sealing Performance  Robust Structural Design  Easy Installation & Removal  Wide Compatibility  Versatile Material Options Global Standard Compliance  Strict Quality Assurance  Customization Flexibility  Efficient Mass Production  Comprehensive Technical Support  Oil & Gas Industry  Chemical Industry  Power Generation  Water Treatment & Municipal Engineering  Marine & Offshore Metallurgy & Mining Đóng gói & vận chuyểnPlastic WasherProtective film and spongeWooden PackageEach flange is separated by a gasket to prevent collisions and scratches.Multiple layers of protective cotton and protective film cover the flange, providing waterproof and anti-fouling properties.Packing in wooden boxes + anti-rust oil.
