How does flange connection work?

A flange connection is an assembly involving two pieces of equipment, pipes, or pipe fittings, two flanges, flange mats, and bolts. Different types of washers are used to secure the connection. To form a seal, force must be exerted and maintained on the opposing flange faces. They are often bolted with a gasket between the faces to form a tight seal, often using a disk spring.
