A flange is a projecting rim, collar, or ring that connects or secures objects together:
FunctionFlanges are used in many industrial and building applications to connect pipes, equipment, or other objects. They can also be used to strengthen or stiffen an object, or to stabilize and guide its movements.
PartsA flange has two main parts: a flange face and flange connection holes. The flange face is mounted onto the object being connected, while the flange connection holes are used to attach the flange to other objects.
AttachmentFlanges are often attached using bolts in a circular pattern. They can be screwed or welded to the object being connected.
SealingFlanges are used to seal pipe systems to prevent leaks. The pressure applied to the mating sealing surfaces causes the two faces to crush a gasket or press together.
MaintenanceFlanges allow for easy access for maintenance, inspection, and modification. They can be used to connect or disconnect pipes without welding, which simplifies installation and reduces downtime.
StandardsFlanges are usually manufactured to standards such as ANSI (American National Standards Institute) or DIN (Deutsches Institut für Normung). These standards define the dimensions, shapes, and locations of the connection holes.
