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.
