Blind Flange is a flange component used to seal the ends of pipes, valves, or containers, typically serving as a temporary or permanent sealing device.
Blind Flange
Is a flange component used to seal the ends of pipes, valves, or containers, typically serving as a temporary or permanent sealing device. It does not have a central hole and appears as a solid disc, connected to other flanges via bolts to isolate the pipeline system, prevent medium leakage, or restrict entry into specific areas. Blind flanges are widely used in industrial pipeline systems, especially in scenarios that require sectional testing, maintenance, or modification.
Various materials such as 16Mn, ASTM A234 carbon steel, 16MnR, 12Cr1MoV alloy steel, and ASTM A403, 1Cr18Ni9Ti stainless steel can be used. The pressure range follows international system standards, including PN2.5, PN6, PN10, PN16, PN25, PN40, PN63, and PN100 (MPa). Product sizes range from DN10 to DN4000 (mm). Sealing surface types such as flat (FF), raised face (RF), male-female face (MFM), tongue-and-groove face (TG), and ring joint (RJ) can be used based on actual requirements.
Blind flanges are an essential sealing component in pipeline systems. With their simple and reliable structure, excellent sealing performance, and broad application scenarios, they have become a critical part of industrial equipment maintenance and safe operation. Whether for routine maintenance or emergency isolation, blind flanges can efficiently perform the task and are an important tool for ensuring pipeline system safety and functional integrity.
