A pipe flange is a protruding rim, edge, collar or rib used to make a connection between two pipes or between a pipe and another component. It is a mechanical connector that is used in high-pressure piping applications.
A builder welds or screws a pipe flange to the pipe end and connects it with bolts. Some common flange types are slip on, weld neck, blind, lap joint and threaded.
Flanges provide increased support to a piping system. Builders use them to dismantle piping systems and transition between dissimilar materials. They use them with temporary and mobile installations and in connections where cement is not used.
