Sealing Faces and Application Scope of Rolling Flanges

Rolling flanges are divided into cold rolling flanges and hot rolling flanges. They are widely applied in the relatively mild conditions such as low-pressure and unpurified compressed air and low-pressure circulating water, and are featured by relatively cheap price.
 
Rolling flanges are applicable for connection of steel pipelines with nominal pressure of no more than 2.5MPa. Sealing faces of rolling flanges include smooth face, male and female face and tongue and groove face, among which, smooth face used for rolling flanges is most widely used and the other two sealing faces are also commonly used.
 
Rolling flanges have many types and model numbers. They have excellent characteristics and performance like good structure, reliable sealing feature, and relatively large strength and rigidity. They can endure high temperature, high pressure and temperature fluctuation. Male and female sealing face is used for rolling flanges with nominal pressure of 0.25~2.5MPa.
