The
flange joint is a sealing component composed of flanges, sealing gaskets and fastening bolts, which plays an important role in connecting pipes, pumps, valves, pressure vessels and various pressure-bearing equipment.
It is the most widely used pipe connector in piping systems and devices in machinery, petroleum, chemical, petrochemical, water conservancy, electric power, light industry, textile, shipbuilding, pharmaceutical and nuclear industries. The
flange joint is not only a detachable connection, but also a pressure-bearing seal. It mainly passes through the flange bolt holes with the help of connecting bolts, and exerts pressure on the flange sealing surface under the action of the applied bolt pretightening force. Compression force, compressing the sealing gasket clamped between a pair of flanges, causing the gasket to undergo plastic deformation or elastic deformation under the action of bolt compression force, so as to fill the micro-geometric gap of the flange sealing surface to achieve Sealing purpose.
As a unit of the
flange joint, the SAE flange usually appears as an independent standard part. Flange components are generally standardized.
