Flange joints are made pressure-tight by inserting a donut-shaped gasket between the flange pairs prior to tightening the bolts.Gaskets are manufactured from materials softer than the flange material. When sandwiched between a pair of flanges, the gasket will be “crushed” between them to seal all potential leak paths.
Flanges differ with regard to their sealing design and required gasket type. In the United States, one of the most common flange “face” designs is the raised-face (RF) flange, designed to seal against a gasket by means of a set of concentric grooves machined on the face of the flange.
