What are Pipe Flanges?

A pipe flange is a protruded rim that help in making a connection between two or more piping equipment. Pipe Flanges can combine or dismantle piping systems or mobile installations to create a transition between dissimilar materials. These Flanges allow room for easy access, cleaning, and inspection. They can be bolted, welded, or screwed following different procedures. There are different Flange Types that are designed to suit different project requirements.

What is RF in flange?

An RF flange is a common flange type in the industry and is easy to identify. The flanges have a raised surface that is raised above the bolting circle where a gasket is placed.

Raised Face Flange vs Flat Face Flange

A flange can be produced either in a raised or flat face specification. A Raised Face Flange has a raised face above the bolting area that allows it to securely seal with a gasket. They ensure a strong sealing and thereby increase the pressure containment capability of the joint.

A Flat Face Flange has a gasket surface that is similar to the face of the bolting circle. These flanges don’t have the same strength as RF flanges and are preferred for lower pressure applications.
