A flange is a critical mechanical component widely used in the connection of piping and equipment. Its primary function is to securely join two or more components-such as pipes, valves, or pumps-using bolted connections, thereby creating a sealed system for fluid transport or containment.
Flanges typically consist of three main elements: the flange body, bolt holes, and the sealing face. The preload applied by the bolts causes elastic deformation at the sealing face, filling minute gaps at the joint to ensure a leak-proof seal. Their design strictly adheres to international standards (such as ASME, DIN, and GB) to ensure interchangeability between products from different manufacturers.
