Basic Components of a Flange

A flange's basic components include the flange plate, sealing surface, bolt holes, and fasteners. The flange plate is the main body of the flange, typically round or square, with its thickness and dimensions varying depending on the specific application. The sealing surface is the part of the flange that contacts the pipe fitting or equipment and provides a seal; its surface is usually specially treated to improve sealing performance. Bolt holes are used to install bolts and other fasteners, ensuring a tight connection between the flanges. Fasteners include bolts and nuts, which are tightened through the bolt holes to securely connect the flanges together.
