There are many types of flanges, which can be classified into different categories according to different standards. Common classification standards include:
Based on the shape of the flange plate, they can be divided into flat flanges, raised face flanges, recessed face flanges, tongue and groove flanges, and ring flanges.
Based on the structure of the flange plate, they can be divided into integral flanges, welded flanges, threaded flanges, compression flanges, and movable flanges.
Based on the connection method, they can be divided into weld neck flanges, socket flanges, flanged flanges, and clamp flanges.
Based on the application environment, they can be divided into high-pressure flanges, low-pressure flanges, high-temperature flanges, low-temperature flanges, and corrosion-resistant flanges.
