A flange can also be a plate or ring to form
a rim at the end of a pipe when fastened to the pipe. 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 generally refers to
the actual raised rim or lip of a fitting, many flanged plumbing fittings are
themselves known as 'flanges':
There are many
different flange standards to be found worldwide. To allow easy functionality
and interchangeability, these are designed to have standardised dimensions.
Common world standards include ASA/ASME (USA), PN/DIN (European), BS10
(British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped
publishing B16.5 in 1996, and the standard is ASME B16.5
