What is the difference between the RF surface and the M flange sheet? Can the two be butted? If not, which flange is the best?
Are you talking about the M surface?. What about the inside of the female flange?
In the flange connection, the convex flange needs to match the concave flange, commonly known as "one male and one female", and the projecting face flange shall be matched with the protruding face flange. In general, the projection flange should also be a type of flat flange, the code name is RF, and the convex flange code is M.You can see the instructions and icons in HG20592-2009. The RF surface can only be linked with the RF surface, and the M face flange needs to be connected with the FM face. The M/FM face is better pressed than the RF surface.
If the pressure is not great, can be connected together, RF and RF seal face to face, is the best M surface with the FM surface to use the best, M surface is generally more than 40 kilograms, including 40 kilograms of flange common flange surface.RF refers to the convex surface, M refers to the convex surface
