Flange

A flange is a projecting rim, edge, or collar, often used to connect components, to provide rigidity or support, or to guide movement. Typically, it's a disc or ring-shaped part that protrudes from a larger body, designed to bolt, clamp, or otherwise attach to another flange or component. The design offers increased surface area, enabling stronger and more reliable connections. Flanges are widely employed in engineering, manufacturing, and construction, notably in pipe systems, machinery, and structural supports, serving diverse functional purposes. The shape, size, and material composition vary depending on the application.

Flange meaning with examples

• The mechanic tightened the bolts on the flange of the exhaust pipe, ensuring a leak-proof seal. The raised rim of the flange allowed for secure attachment and resistance to high temperatures and pressure. This simple mechanism prevents exhaust fumes escaping.
• Workers welded the flange onto the steel beam, preparing for the next phase of the construction project. The flange provided stability and a strong point for connection to other structural elements. The design enabled the builder to attach multiple different building materials.
• The engineer designed a flange with several bolt holes for the pump casing, making it easily removable for maintenance. The strategic placement of the holes ensured even pressure distribution during operation. The added surface area of the flanges prevents stress cracks from starting.
• During the plumbing work, the plumber used a flange to connect the water pipe to the faucet. The flange enabled a secure and watertight connection, preventing any leaks. The shape of the pipe will be a perfect seal when it's tightened to the other flange.
• The machine shop used a flange on a rotating shaft of the motor to attach a gear, which provides stability. The strong connection transmits rotational force, driving the machinery. The extended area of the flange allows for reliable torque transmission.
