Plate Flange

​

Plate Flange

A plate flange  is a flat, circular disk that is welded onto the end of a steel pipe and allows it to be bolted to another pipe. Typically used in fuel and water pipelines, the two flange plates will be bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions,tees and joints. (Know more about plate flange)
