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 Advantages
- Reliable 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.
