Blind Flange
Keywords:
Blind Flange (BL) is a flange with a solid disc structure, used to seal the end of the pipeline, prevent the leakage of medium and protect the internal structure of the pipeline. It is connected to the pipeline by bolting, with a simple structure, reliable sealing and strong pressure resistance, and is widely used in all types of pipeline systems that need to be sealed temporarily or permanently. As an essential sealing component in pipeline systems, it perfectly meets the needs of international trade and various project applications.Core AdvantagesReliable Sealing: Solid disc structure, combined with high-precision sealing surface and gasket, ensures reliable sealing, preventing medium leakage.Strong Pressure Resistance: Thick disc design, strong bearing capacity, suitable for low, medium and high pressure pipeline systems.Simple Structure & Easy Installation: No complex processing, easy to bolt and install, convenient for disassembly and maintenance when needed.Wide Application: Suitable for all types of pipeline systems, can be used for temporary sealing (maintenance, inspection) or permanent sealing of pipeline ends.Global Standard Compliance: Strictly manufactured in accordance with international and national standards, fully adapting to global market requirements.Key SpecificationsStandards: International Standard (ISO 7005), American Standard (ASME B16.5), German Standard (DIN 2501), European Standard (EN 1092-1), Japanese Standard (JIS B2220), Chinese Standard (GB/T 9113, HG/T 20592, HG/T 20615)Materials: Carbon steel (A105, 20#, Q235B), stainless steel (304, 316L), alloy steel (16Mn, F11, F22) — customizable according to medium and working conditions.Pressure Ratings: Class 150, 300, 600, 900, 1500, 2500; PN10, PN16, PN25, PN40, PN63, PN100Nominal Diameter: DN15 ~ DN2000 (NPS 1/2" ~ 80")Sealing Surface Types: RF (Raised Face), FF (Flat Face), RTJ (Ring Type Joint), MFM (Male-Female Face)Working Temperature: -40℃ ~ 600℃ (customizable for high-temperature special requirements)ApplicationsWidely applied in petroleum, petrochemical, natural gas, power generation, chemical engineering, water supply and drainage, HVAC and other industries. It is an essential sealing component for pipeline systems, used for sealing pipeline ends, equipment interfaces, and temporary sealing during pipeline maintenance and inspection, and is exported to countries and regions around the world, winning unanimous recognition from global customers.As a professional manufacturer based in Cangzhou Pipeline Equipment Manufacturing Base, Hebei, China, we provide customized services for Blind Flanges according to customer drawings, specifications, materials and standards, and offer one-stop supply and after-sales support to meet the personalized needs of global projects.
