What is a flange?

A flange is a protruding rim or edge on a pipe or valve that allows for the attachment of another object, such as a pipe or fitting. It provides a means for joining or connecting sections of piping systems.

What are the advantages of stainless steel flanges?

Stainless steel flanges offer superior corrosion resistance, durability, and strength compared to other materials. They are suitable for a wide range of applications, including those requiring high temperatures or exposure to corrosive environments.

How do I choose the right type of flange for my project?

The type of flange you choose depends on factors such as the application, pressure, temperature, and pipe specifications. Consult with a knowledgeable supplier or engineer to determine the most suitable flange type for your specific project requirements.
