Introduction to flange products
Basic concepts and applications of flanges
Flanges, also known as flange discs or flanges, are important pipeline connecting components mainly used for connecting pipe ends and widely used for connecting equipment inlets and outlets, such as reducer flange 1. The flange connection is a detachable connection method that combines flanges, gaskets, and bolts to form a combined sealing structure, ensuring the tightness and sealing of the connection.
