Flanges are integral parts of many engineering and plumbing projects.
many applications, engineers need to find a way to close off a chamber or
cylinder in a very secure fashion, usually because the substance inside must
differ from the substance outside in composition or pressure. They do this by
fastening two pieces of metal or other material together with a circle of bolts
on a lip. This “lip” is a flange.
You can connect two sections of metal piping by
soldering or welding them together, but pipes connected in this way are very
susceptible to bursting at high pressures. A way of connecting two sections of
pipe more securely is by having flanged ends that you can connect with bolts.
This way, even if gases or liquids build up to high pressures inside the pipe,
it will often hold with no problem.
In order to connect two sections of a large,
enclosed area, it is often best to used flanges and bolts. An example of this is
the connection between the engine and the transmission in an automobile. In this
case, both the engine and the transmission contain a number of moving parts that
can easily get damaged if they get dust or other small objects inside of them.
By connecting the outer casings of the engine and transmission in this way,
engineers protect the inner workings of both.
Flanges have a specific purpose in cameras
and other electronic devices. Though flanges in such items do not usually have
to sustain high pressures, they do have to hold tight so they can keep out
harmful particles. These flanges are usually found connecting two different
materials, such as the glass of a lens and the rest of the body of the
