There is a common type of large-diameter flange with mortise and tenon surface. Large diameter flange with mortise and tenon surface and butt weldingLarge diameter flangeThe structure and usage environment vary, so it is necessary to use it according to different scopes. Large diameter flanges with mortise and tenon surfaces have good rigidity and can be used in situations with high pressure and temperature. The types of flange sealing surfaces include: flat sealing surfaces, installed in environments with low pressure and no toxic media; Concave convex sealing surface, installed for use in environments with higher pressure; The sealing surface of the large diameter flange with mortise and tenon groove can be installed in places with flammable, explosive, toxic media and high pressure.
