Pipe Flange Information:

Flanges are relatively simple mechanical connectors that have been used successfully for high-pressure piping applications. They are well understood, reliable, cost-effective, and readily available from a wide range of suppliers. Pipe flanges are protruding rims, edges, ribs, or collars used to make a connection between two pipes or between a pipe and any type of fitting or equipment component.

Pipe flanges are used for dismantling piping systems, temporary or mobile installations, transitions between dissimilar materials, and connections in environments not conducive to solvent cementing

In addition, the moment-carrying capacity of flanges is significant compared to other mechanical connectors. This is an important feature for systems that experience pipe-walking or lateral buckling from temperature and pressure variations (e.g. deep water lines). Flanges can be designed to meet a wide range of application requirements, such as high temperature and corrosion resistance.

Operation

Pipe flanges have flush or flat surfaces that are perpendicular to the pipe to which they attach. Two of these surfaces are mechanically joined via bolts, collars, adhesives or welds.

Types of Flanges:

• Pipe flanges

• Blind flanges

• Lap joint flanges

• Slip-on flanges

• Socket weld flanges

• Threaded flanges

• Welding neck flanges

Typically, flanges are attached to pipes via welding, brazing, or threading.

Flange Dimensions

Physical dimensions should be specified in order to size flanges correctly.

• Bolt circle diameter

• Pipe size

• Nominal bore size

Flange Faces:

• Flat
• Raised face (RF)
