What Is the Difference Between a Flangeolet and a Standard Flange?

−

A standard flange is primarily used to connect two pipes, valves, or equipment sections.

A Flangeolet, however, is specifically designed to create a branch connection from a main pipeline while incorporating a flanged outlet, making it ideal for branch piping applications.

Where Are Flangeolets Commonly Used?

+

Flangeolet Fittings are widely used in industries such as oil & gas, petrochemical processing, power generation, refineries, chemical plants, marine applications, and water treatment facilities where strong and reliable branch connections are required.

Are Flangeolets Leak-Proof?

+

Yes, when properly installed and used with suitable gaskets and bolting systems, Flangeolet Fittings provide a secure and leak-resistant connection. Their robust design makes them highly reliable for high-pressure and high-temperature industrial applications.
