What is a flange in engineering?

A flange is a projecting ridge, rim, collar or ring on an object such as a column, beam, pipe and so on that provides additional strength or stiffness or additional surface area for the attachment of, or to, another object. For example, flanges may be used to strengthen beams, or to connect or terminate pipes.

What is flange in construction?

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification.

What are flanges classified?

The key types of flanges are the welding neck, long welding neck, slip-on, socket weld, lap joint, threaded and blind flanges. In addition to these standard flanges, some special ones exist, called Weldoflange/Nipoflange and Elboflange, swivel flange, expander/reducer flange, and orifice flanges.

What is flange and web?

Let’s start with the basics: The horizontal pieces are known as flanges, and the vertical piece is called the web. The flanges resist bending while the web takes on the shear force. A wide flange beam, with wider flanges and web than the I-beam, can handle more weight, but this makes it heavier overall.
