What is the function of flange?

Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels.

Why are pipe flanges important?

Flanges are helpful to connect pumps, valves, pipes, and other parts to form a piping system. The use of flanges allows a person for maintenance and easy repair of the pipe system.

How many types of flanges in piping?
