A sealing component composed of SAE flange, sealing gasket, and fastening bolt, mainly used for the connection and pressure bearing between hydraulic pipelines, and is a type of pipeline connector.

SAE flanges are widely used in pipeline systems and installations in sectors such as petrochemicals, machinery, water conservancy, electricity, light industry, textiles, ships, pharmaceuticals, and nuclear industry.

SAE flange is only a unit in the flange sealing joint, usually appearing as an independent standard part, but it is closely related to the sealing gasket and the bolts connecting the flange. Therefore, from the perspective of flange design calculation, the bolts connecting the flange and the gaskets that play a sealing role should be considered as a whole from beginning to end.
