Flanges


Pipe flanges are widely used as a popular category of pipe fittings. A flange is used to mechanically connect two pipes together. It can also be used to connect a pipe to a tee, valve, choke or any other piece of equipment. Flanges are available in round, square, and rectangular shapes. In some cases, flanges are usually in the shape of a ring or a plate to form a rim at the end of a pipe when fastened to the pipe. This is an example of closet flange.


A flange can also be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered the projecting or internal components which are used to support mechanical parts. They are like rims which are used to strengthen the mechanical part or they are a means of attaching that part to another part or surface.

Flange Connection


Offering a reliable way to connect pipe systems with the various equipment, valves, and other components of virtually any processing system, flanges are the second most used joining method after welding.

Using flanges adds flexibility when maintaining piping systems by allowing for easier disassembly and improved access to system components.

A typical flanged connection is comprised of three parts:

  • Pipe Flanges

  • Gasket

  • Bolting

In most cases, there are specific gasket and bolting materials made from the same, or approved materials as the piping components you wish to connect. Stainless Steel flanges are some of the most common. However, flanges are available in a wide range of materials so matching them with your needs is essential.

Other common flange materials include Monel, Inconel, Chrome Moly, and many others depending on the application.

The best option for your needs will depend on both the system in which you intend to use the flange and your specific requirements.
