Flanges are integral parts of many engineering and plumbing projects.
The usual materials of flanges include stainless steel, carbon steel, aluminum and plastic. The choice of the material largely depends on the purpose of the flange.

Each flange ASME B16.5 has a number of standard dimensions. If a draftsman in Japan or a work preparer in Canada or a pipefitter in Australia is speaking about a Welding Neck flange 6″-150#-S40 ASME B16.5, then it goes over the flange which in the image here on the left is shown.
The user profile of pipe flanges is quite extensive. Suffice it to say that any entity that has something to do with pipes is likely to use these flanges.

Materials for gaskets can be divided into three main categories as Non-Metallic types, Semi-Metallic types, Metallic types. Non-Metallic gaskets are usually composite sheet materials are used with flat-face and raised-face flanges in low Pressure Class applications.
American Water Works Association (AWWA) is an international non-profit, scientific and educational association founded to improve water quality and supply.
Flanged joints are made by bolting together two flanges with a gasket between them to provide…
the standards for flange are replaced by DIN EN 1092-1
One of the best all-around seals, the spiral wound gasket offers a low-cost solution that has the ability to handle temperature and pressure fluctuations.
Blind flange is put at the end of pipe or at the junction that would possibly be a future expansion into that direction. Blind pipe flanges are often used for high pressure applications.
