Applications of Blind Flanges


Pressure Vessels: Blind flanges are used to seal the ends of pressure vessels, tanks, and reactors during maintenance, cleaning, or inspection.

Pipeline Terminations: They are used to close off the ends of pipelines temporarily or permanently, especially in dead-end sections or where the pipeline is not yet connected to another component.

Isolation of Equipment: Blind flanges are used to isolate equipment such as pumps, valves, and meters from the rest of the piping system for maintenance or repair purposes.

Testing and Inspection: They are used in hydrostatic or pneumatic pressure testing of piping systems to isolate sections of the system and verify the integrity of the joints.

Flushing and Purging: Blind flanges are used to seal off piping systems during flushing, purging, or cleaning operations to prevent contamination or fluid leakage.



Advantages of Blind Flanges


As a blind flange manufacturer, we make sure our blind flanges have :

Versatility: Blind flanges can be used in a wide range of applications to seal off the ends of piping systems, vessels, or equipment.

Temporary or Permanent Sealing: They can be installed temporarily for maintenance or testing purposes and permanently for equipment decommissioning or abandonment.

Leak-Proof Seal: Blind flanges provide a secure and leak-proof seal when properly installed and tightened, preventing fluid or gas leakage.
