Flanges

Dimensions & materials acc. to ASTM, API, ANSI/ASME, MSS SP, DIN, BS, EN

The many types of flanges are mainly used to connect mechanically two pipes together. Flanges allows also one pipe to be mechanically connected to a valve, fitting or other equipment.

The principle of a flange is to use a mechanical force by using bolts to preload the gasket until there is enough contact stress between the flanges and the gasket to maintain a seal. The connection to pipe is done by welding or threaded connections.
