Blind Flange - Overview
A blind flange is a solid disk used to block off a pipeline or terminate the end of a piping system. Unlike standard flanges, it lacks a center bore, making it ideal for isolation, pressure testing, or future expansion purposes.
Key Features:
Design: No internal opening, with bolt holes around the perimeter for secure attachment.
Materials: Commonly made from carbon steel, stainless steel, alloy steel, or other materials to match pipeline specifications.
Pressure Rating: Complies with ANSI/ASME, DIN, EN, or other standards, available in various pressure classes (e.g., 150#, 300#).
Applications:
Temporary or permanent sealing of pipelines.
Safety isolation during maintenance.
Pressure test points in systems.
Advantages:
Provides leak-proof closure.
Easy to install/remove for inspection.
Compatible with multiple gasket types (e.g., rubber, PTFE).
Blind flanges are critical in industries like oil & gas, chemical processing, and water treatment, ensuring system integrity and operational flexibility.
