6.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 also used with the flange connection to secure the connection.
Besides, a flange connection culminates in joining two materials using inner and outer lip parts or flanges. For each of the opposing flange faces to form a seal, force (gasket compression or sealing pressure) must be exerted and maintained. To ensure flanges stay in place, they are often bolted with a gasket between the flange faces to form a tight seal. One of the gaskets often used for this sealing is a disk spring, which is a type of spring.
