Flanges

Flanges are used to connect valves, pipes, pumps and other equipment to make a pipework system. Typically flanges are welded or threaded, and two flanges are connected together by bolting them with gaskets to provide a seal that provides easy access to the piping system. These Flanges are available in various types such as slip on flanges, weld neck flanges, blind flanges, and socket weld flanges, etc. Below we have explained the various types of flanges used in the piping systems depends on their sizes other factors.
