A flange is an external or internal ridge, or rim,
for strength, as the flange of an iron beam such as an I-beam or a T-beam; or
for attachment to another object, as the flange on the end of a pipe, steam
cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car
or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep
the wheels from running off the rails. The term "flange" is also used
for a kind of tool used to form flanges produced by duplex steel fittings
manufactures. Pipes with flanges can be
assembled and disassembled easily. Some of the materials used to manufacture
flanges are cast iron, carbon steel, duplex steel.
A flange can also be a plate or ring to form a rim at the end of a
pipe when fastened to the pipe (for example, a closet flange). A blind flange
is a plate for covering or closing the end of a pipe. A flange joint is a
connection of pipes, where the connecting pieces have flanges by which the
parts are bolted together. Although the word flange supplied from duplex
steel flange suppliers generally refers to the actual raised rim or lip of a fitting, many
flanged plumbing fittings are themselves known as 'flanges':
Common flanges which you can get from stainless steel forged flanges wholesale used in plumbing are the
Surrey flange or Danzey flange, York flange, Sussex flange and Essex flange.
Surrey and York flanges fit to the top of the hot water tank allowing all the
water to be taken without disturbance to the tank. They are often used to
ensure an even flow of water to showers. An Essex flange requires a hole to be
drilled in the side of the tank. There is also a Warix flange which is the same
as a York flange but the shower output is on the top of the flange and the vent
on the side. A closet flange provides the mount for a toilet.
